步驟S3-配合參閱圖2、圖3,在金屬板材5遠離母模 座2 一側施予流體加壓。在本實施财，辭龍加㈣動 作是透過由加壓裝置4輸人流體至密封模3而達成，當金屬 板材5放置在母模座2上時，即驅動密封模3鄰近母模座2 並且壓蓋於金屬板材5上，此時，藉由密封模3麼蓋於金屬 板材5上而使第—空間34形成—個密閉空間，因此，當流 體由加壓裝置4輸人密封模3時，便可形成壓力對金屬板材 5，壓。在本實施例中’流體是氮氣，冑際上可用氨氣或氮 氣等惰性氣體’或其混合氣體取代，亦可用对高溫的液體， 如油類代替。 步驟S4—配合參閱圖3 '圖4，與步驟&同步進行對 金屬板材5施以第二熱處理，使金屬板材5至少部分地對應 進入成型槽221中而成型，該成型金屬板材5界定出至少一 凹陷結構51。在本實施例中，是將電熱管12置入加熱孔112, 並啟動以增溫方式加熱5秒至5分鐘，其溫度是介於至 550°C中任一區段，例如可以選取45〇至50(rc的區段，同時， 藉由加壓裝置4由加壓口 33持續輸入流體至呈密閉狀態的 15 201008675 第一空間34，使得壓力持續上升，藉此將受熱的金屬板材$ 推擠進入成型槽221中，當壓力到達uooKg/cm2範圍時（通 常是到達1〜60Kg/cm2範圍時），便可使金屬板材5貼合於成 型槽221的槽壁，並對應形成與成型用紋路223互補的形 狀’即如圖4所示完成熱壓模製成型，此時金屬板材$遠離 該母模座2 —側，在外觀上會對應四個成型槽221凹陷而產 生四個凹陷結構51 (圖中僅顯示兩個）。 步驟S’ 一配合參閱圖4、圖6、圖7，以至少一脫模塊 72對應置入該凹陷結構51中。在本實施例中，是利用脫模 ® 子裝置200對已熱壓模製成型的金屬板材5進行脫模，且在 脫模之前，是先將已熱麼模製成型的金屬板材5連同母模座 2由加熱台1移到冷卻台6的平面611上，接著，如圖6與 圖7所示’驅動脫模單元7鄰近冷卻台1上的母模座2並且 蓋壓於金屬板材5遠離該母模座2的一側，使各個脫模塊72 對應置入金屬板件5的各個凹陷結構51中。 參閲圖5、圖7、圖8，且值得注意的是，當脫模單元7 蓋壓於金屬板材5遠離母模座2的一側時，脫模單元7的脫 ❹ 件刀模73亦同時將金屬板材5沿成型槽221開口周圍切割， 使金屬板材5被分切成四個模製物件5,，此處用意在於，由 於當金屬板材5連同母模座2由加熱台1移到冷卻台6準備 進行脫模之前，金屬板材5的溫度會逐漸降低，使金屬板材 5開始產生收縮現象’再加上母模座2的結構關係，請回頭 參閱圖4,於是，金屬板材5的收縮便會導致金屬板材5的 b區與c區相對夾緊在母模座2上，造成金屬板材5咬合在 16 201008675 兩相鄰的成型模22之間，使金屬板材5難以脫離母模座2, 故爲避免上述狀況，故此處遂使脫模單元7蓋壓於金屬板材 5時’脫模單元7的脫件刀模73 |5]時將金屬板材5分切成四 個模製物件5’ ’以消除金屬板材5咬合在母模座2的現象。 步驟S6—配合參閱圖7,對該成型的金屬板材5進行冷 卻處理，使該成型的金屬板材5收縮夾附於該脫模塊72上。 參閱圖7 ’當模製物件5’被分切形成，且脫模塊72分別對應 谷置入凹陷結構51後，便可進行冷卻處理，在本實施例中， 疋分別對座體61的冷卻孔612及脫模單元7的通道74灌注 冷卻水（如圖7中箭頭所示），冷卻時間約為1〇秒至5分鐘 (通常為10秒至3分鐘），透過冷卻台6及脫模單元7對模 製物件5’進行冷卻，使模製物件5，冷卻收縮。由於圖7的压 區經過上述切割，收縮作用已無法使b區與c區相對夾緊在 母模座2上，此外，也由於冷卻收縮的緣故，會使得圖7中 左側的模製物件5,的b區與f區夾緊在左側的脫模塊72上， 而右側的模製物件5’的c區與e區夾緊在右側的脫模塊72 上，另外，雖然d區收縮亦產生夾緊在成型用紋路223的狀 況，但相對影響較小。 再者，由於脫模塊72在尺寸的設計上，考慮到鎂合金 在成型後會產生約0.3%的收縮率，以寬度舉例說明，大致上 疋略小於凹槽212寬度減去兩倍金屬板材5厚度，使脫模塊 72對應置入凹陷結構51時，圖7中右側的脫模塊72能夠同 時接觸貼合c區及e區，而左側的脫模塊72能夠同時接觸貼 合b區及f區，而長度上的設計亦同理，換句話說，就是使 17 201008675 模製物件5’受冷卻收縮後能夾附於脫模塊72上。 步驟S7一配合參閱圖9、圖10,將脫模塊72連同成型 金屬板材5由母模座2上移除而脫模。經過冷卻處理使模製 物件5由於冷卻收縮而分別夾附於脫模塊72上，便可將脫 模單元7由母模座2上移除，而模製物件5，便會連帶地由成 型槽221脫離，然後便可由模製物件5，邊緣將其由脫模塊 上分離（如圖1〇的箭頭所示），完成整個脫模過程。 幾點補充說明的是，上述的脫件刀模73亦可是活動式， 即獨立於主板71彳，只要能先將金屬板材5沿成型槽221 〇 開口周圍切割，形成四個模製物件5，即可。 此外，上述脫模方式，即使成型槽22丨的槽壁每—側都 開《c成型用紋路223，也可以藉由收縮夾附於脫模塊72上而 有效地脫模，不會因為咬合在成型用紋路223而卡死無法退 模，因此模製物件5,最多可以在五側都對應形成浮凸紋路， 即有五個浮離表面。 再者，在本實施例的成型方法中，透過步驟心先對金屬 板材5進行第一熱處理以及步驟&中增溫方式的第二熱處 0 理，可更進一步降低鎂合金在成型過程中容易發生斷裂的現 象。 接下來討論模製物件5,的表面效果與預熱溫度、預熱時 間及成型溫度的關係，以下將相關測試資料列於表一及表二 以進行詳細討論比較。表一及表二是利用兩家不同廠牌的 AZ31B鎂合金板材（分別以A板材與8板材表示）來進行 熱壓模製成型，鎂合金板材厚度為〇.6 mm，以 20Kg/cm2 的 18 201008675 壓力，分別進行不同溫度及時間的預熱，再配合不同溫度及 方式的成型加溫3分鐘，另外，成型槽221的成型用紋路223 刀別s又s十成一長度15 mm v深度1 mm，寬度1 mm的第一紋 路槽’及一長度15 mm ’深度1 mm，寬度2 mm的第二紋路 槽’而在成型之後，模製物件表面會對應第一紋路槽及第二 紋路槽形成兩個長條狀凸肋，而表中的「表現丨」即是對應 第一紋路槽的長條狀凸肋的最大起伏高度，而「表現2」即 是對應第二紋路槽的長條狀凸肋的最大起伏高度，其測量誤 差是 ±0.005 mm。 首先參閲表一，其中編號入11、八12、八13、入21、八22、 A23、A31、A32、A33是第一熱處理溫度與第二熱處理的溫 度相同的成型方式’即一般傳統方式的成型測試結果，而 A6卜 A62、A63、A7卜 A72、A73、A8 卜 A82、A83、A91、

成型效果會變差，因此第二熱處理的溫度較佳地是介於 380〜52(TC。另外，第一熱處理相較於第二熱處理溫度（指 最低溫）的溫度，低越多則成型表現越好，但第一熱處理低 於250°C以下，則效果較差，若高於450°C，則無法有效拉 大與成型溫度之間的差異，所以第一熱處理較佳地是以介於 250〜450°C的定溫方式實施。而由A41、A42、A43、A51、 A52、A53 及 B41、B42、B43、B51、B52、B53 的資料顯示， 當第一熱處理的溫度明顯低於第二熱處理溫度時，則即使第 二熱處理是以定溫方式加溫，亦可產生較佳的成型表現，大 致上，第一熱處理的溫度比第二熱處理溫度低20°C以上即可 產生較佳成型表現。另外，從表一及表二來推算，成型表現 的細緻度大致可達0.01 mm。 本發明利用上述成型方法而可對鎂合金進行成型，使金 屬板材5可具有數量五個以下的浮雕表面，並呈現〇.01mm 的細緻度，且配合第一熱處理以及增溫方式的第二熱處理， 23 201008675 也可降低鎂合金在成型過程中斷裂的機率，而所生產的模製 物件5,，更具有以下多項優點··⑴產品良率高·在上述溫 壓範圍内，生產良率可達99%以上；⑺浮雕成型：最多可 形成五個浮雕表面，·（3)表面優質：模製物件表面平滑細緻， 可做電鑛、陽極等高階的表面處理；（4)安全性高：由於， 模製物件表面平滑細緻，不必再研磨處理可避免產生易燃 的鎂屑’（5)單模成型：使用母模具無公模具，開模容易成 本低，（6)脫模容易：工件直接接觸脫模裝置冷卻工件收 縮後直接夾附於脫模裝置脫模，模具無須潤滑劑、脫模劑；© (7)大面積成型：成型面積可達5〇〇mmx 5〇〇mm以上一 次成型可得大量模製物件，生產速度快。 綜上所述，本發明成型方法，利用母模座2及密封模3 實施流體加壓，並配合兩階段式的第一熱處理及第二熱處 理，使金屬板材5成型，再藉由脫件刀模73將成型金屬板 材5切割成模製物件5’ ’並藉由冷卻處理使模製物件5，收縮 夹附於脫模塊72上，再移除而脫模，使金屬板材5可具有 五個以下的浮雕表面，並呈現〇 〇lmm的細緻度，故確實能 © 達成本發明之目的。 惟以上所述者，僅為本發明之較佳實施例而已，當不能

Figs. 2 and 3, fluid pressure is applied to the side of the metal sheet 5 away from the mother mold base 2. In the present implementation, the operation of the vocabulary (4) is achieved by the fluid from the pressing device 4 being applied to the sealing die 3. When the metal sheet 5 is placed on the female mold base 2, the driving sealing die 3 is adjacent to the female mold base 2 And the cover is pressed on the metal plate 5, at this time, the sealing space 3 is covered on the metal plate 5, so that the first space 34 forms a closed space, and therefore, when the fluid is injected into the sealing die 3 by the pressing device 4. When the pressure is applied to the metal sheet 5, the pressure is formed. In the present embodiment, the "fluid is nitrogen gas, and may be replaced by an inert gas such as ammonia gas or nitrogen gas" or a mixed gas thereof, or may be replaced with a high-temperature liquid such as oil. Step S4 - Referring to FIG. 3 ' FIG. 4 , a second heat treatment is applied to the metal sheet 5 in synchronization with the step & the metal sheet 5 is at least partially correspondingly formed into the forming groove 221, and the forming metal sheet 5 is defined. At least one recessed structure 51. In this embodiment, the electric heating tube 12 is placed in the heating hole 112, and is started to be heated in a warming manner for 5 seconds to 5 minutes, and the temperature is in any section up to 550 ° C, for example, 45 可以 can be selected. Up to 50 (the section of rc, at the same time, by the pressurizing device 4, the fluid is continuously input from the pressurizing port 33 to the first space 34 in the closed state of 15 201008675, so that the pressure continues to rise, thereby pushing the heated metal sheet $ When it is squeezed into the molding groove 221, when the pressure reaches the range of uooKg/cm2 (usually when it reaches the range of 1 to 60 Kg/cm2), the metal plate 5 can be attached to the groove wall of the molding groove 221, and correspondingly formed and molded. The complementary shape of the texture 223 is completed as shown in FIG. 4, and the metal plate material is away from the side of the mother die holder 2, and the appearance is corresponding to the depression of the four molding grooves 221 to generate four depressions. The structure 51 (only two are shown in the figure). Step S', with reference to Fig. 4, Fig. 6, and Fig. 7, the at least one off module 72 is correspondingly placed in the recessed structure 51. In this embodiment, The mold sub-assembly 200 demolds the hot stamped metal sheet 5, and Before demolding, the hot-formed sheet metal 5 is transferred from the heating stage 1 to the plane 611 of the cooling stage 6 together with the master mold base 2, and then, as shown in FIGS. 6 and 7 The demolding unit 7 is adjacent to the female mold base 2 on the cooling table 1 and is pressed against the side of the metal sheet 5 away from the female mold base 2, so that the respective stripping modules 72 are correspondingly placed in the respective recessed structures 51 of the metal plate member 5. Referring to FIG. 5, FIG. 7, and FIG. 8, it is noted that when the demolding unit 7 is pressed against the side of the metal plate 5 away from the female mold base 2, the disengagement die 73 of the demolding unit 7 is also At the same time, the metal sheet 5 is cut around the opening of the forming groove 221, so that the metal sheet 5 is divided into four molded objects 5, which is intended to be moved from the heating table 1 to the metal sheet 5 together with the female mold base 2 Before the cooling table 6 is ready for demolding, the temperature of the metal sheet 5 will gradually decrease, and the metal sheet 5 will begin to shrink. With the structural relationship of the mother mold base 2, please refer back to FIG. 4, and then, the metal sheet 5 The shrinkage causes the b-zone and the c-zone of the metal sheet 5 to be relatively clamped on the female mold base 2, resulting in the metal sheet 5 In the case of 16 201008675 between two adjacent molding dies 22, the metal sheet 5 is difficult to be detached from the mother mold base 2, so in order to avoid the above situation, the demolding unit 7 is pressed against the metal sheet 5 here. The stripping die 73 | 5] of the 7 is divided into four molded articles 5'' to eliminate the phenomenon that the metal plate 5 is engaged in the female die holder 2. Step S6 - cooperate with reference to FIG. The formed metal sheet 5 is subjected to a cooling treatment, and the formed metal sheet 5 is contracted and attached to the stripping module 72. Referring to Fig. 7 'When the molded article 5' is formed by slitting, and the stripping module 72 is respectively placed corresponding to the valley After the recessed structure 51, the cooling process can be performed. In the present embodiment, the crucible is respectively filled with cooling water 612 of the seat body 61 and the passage 74 of the demolding unit 7 (as indicated by an arrow in FIG. 7), cooling time. The molded article 5' is cooled by the cooling table 6 and the demolding unit 7 for about 1 second to 5 minutes (usually 10 seconds to 3 minutes) to cool and contract the molded article 5. Since the nip of Fig. 7 is subjected to the above-described cutting, the contraction has prevented the b-zone and the c-zone from being relatively clamped on the master mold base 2, and further, due to the cooling shrinkage, the molded article 5 on the left side in Fig. 7 is caused. The b zone and the f zone are clamped on the left side of the stripping module 72, and the c zone and the e zone of the right molded article 5' are clamped on the right side of the stripping module 72, and in addition, although the d zone shrinks, the clip is also generated. It is in the condition of the molding grain 223, but the relative influence is small. Moreover, due to the size design of the stripping module 72, it is considered that the magnesium alloy will produce a shrinkage of about 0.3% after molding, and by way of example, the width is substantially smaller than the width of the groove 212 minus twice the metal sheet 5 When the stripping module 72 is correspondingly placed into the recessed structure 51, the stripping module 72 on the right side of FIG. 7 can simultaneously contact the bonding c zone and the e zone, and the stripping module 72 on the left side can simultaneously contact the b zone and the f zone. The design of the length is also the same, in other words, the 17 201008675 molded article 5' can be attached to the stripping module 72 after being cooled and contracted. Step S7, together with reference to Fig. 9 and Fig. 10, the stripping module 72 together with the forming metal sheet 5 is removed from the master mold base 2 to be demolded. After the cooling treatment causes the molded article 5 to be respectively attached to the stripping module 72 due to cooling shrinkage, the demolding unit 7 can be removed from the master mold base 2, and the molded article 5 can be jointly formed by the forming groove. The 221 is detached, and then the molded article 5, the edge is separated from the detachment module (as indicated by the arrow in Fig. 1), and the entire demolding process is completed. It should be noted that the above-mentioned release die 73 can also be movable, that is, independent of the main plate 71彳, as long as the metal plate 5 can be cut along the opening of the molding groove 221 to form four molded objects 5, Just fine. In addition, in the above-mentioned demolding method, even if the groove for forming the molding groove 223 is opened every side of the groove wall of the molding groove 22, the mold can be effectively released by shrinking the clip to the stripping module 72, without being bitten in the groove. Since the molding grain 223 is stuck and cannot be demolded, the molded article 5 can form a embossed pattern corresponding to at most five sides, that is, there are five floating surfaces. Furthermore, in the molding method of the present embodiment, the first heat treatment of the metal sheet 5 and the second heat treatment in the step & temperature increase mode can further reduce the magnesium alloy during the molding process. It is prone to breakage. Next, the relationship between the surface effect of the molded article 5 and the preheating temperature, the preheating time and the molding temperature will be discussed. The relevant test data are listed in Tables 1 and 2 for detailed discussion and comparison. Tables 1 and 2 show the hot-press molding of AZ31B magnesium alloy sheets (represented by A sheets and 8 sheets, respectively) of two different brands. The thickness of the magnesium alloy sheets is 〇6 mm to 20 Kg/cm2. The pressure of 18 201008675 is preheated at different temperatures and times, and then heated for 3 minutes with different temperatures and modes. In addition, the molding groove 221 is formed with a pattern 223 and a length of 15 mm. 1 mm, 1 mm width of the first groove groove' and a length of 15 mm '1 mm depth, 2 mm width of the second groove groove' and after molding, the surface of the molded object corresponds to the first groove groove and the second grain groove The groove forms two long ribs, and the "performance 丨" in the table is the maximum undulation height of the long rib corresponding to the first groove, and "performance 2" corresponds to the length of the second groove. The maximum undulation height of the strip ribs is ±0.005 mm. First, refer to Table 1, where the numbers 11, 8, 12, 13, 21, 82, A23, A31, A32, and A33 are the same forming method as the first heat treatment temperature and the temperature of the second heat treatment. The molding test results, and A6, A62, A63, A7, A72, A73, A8, A82, A83, A91, A92, and A93 are molding test results using the warming method of the present invention. From the "performance 1", the traditional way shows the undulation height of 〇·〇57~0.073 mm, while the temperature increase method shows 0.129~0.173 mm, and from the performance 2, the traditional way shows 0_203~0.421 The undulation height of mm, and the way of warming is 0.545~0.776 mm. Obviously, it is formed by increasing temperature, and its performance is better, about 1 time difference. In addition, under the conditions of temperature increase (420~500 °C or 450~500 °C), a group with a lower preheating temperature (25CTC) (A91, A92, A93) performs best. It is worth mentioning that if the first heat treatment temperature is significantly lower than the second heat treatment temperature, for example, the temperature difference of 150 °C exhibited by A41, A42, A43, or 25 (TC temperature difference ' of A51, A52, A53 Even if the second heat treatment is heated at a constant temperature, the "performance 1" and "performance 2" of the sample produced by X9 201008675 are better than those of other samples heated at a constant temperature.

From "Performance 1", the traditional way is to show the undulation height of 〇·〇58~0.077 mm, and the temperature increase method is 0.142 ~ 0.189 mm, and from the performance 2, the traditional way is 0.205~0.449 The undulation height of mm and the temperature increase method are 0.604~0.845 mm. Similarly, the performance of molding by temperature increase is better, and the difference is about 1 time. In addition, under the conditions of temperature increase mode, a group with a lower preheating temperature (250 °C) (B91, B92, B93) has the best performance. Similarly, if the first heat treatment temperature is significantly lower than the second heat treatment temperature, for example, the temperature difference of 150 ° C exhibited by B41, B42, B43, or the temperature difference of 250 ° C exhibited by B51, B52, B53, even if the second The heat treatment is performed by heating at a constant temperature. 'Performance 1' and 'Performance 2' produced by the sample are also better than those of the other second heat treatment which are heated at a constant temperature. 21 201008675 Table 2: Forming performance of B sheet under different temperature and time conditions No. First heat treatment temperature Preheating time Second heat treatment temperature Engraving width 1 Carving width 2 B11 450〇C 0.5 minutes 450°C Constant temperature 0.063mm 0.249mm B12 450〇C 2 minutes 450°C constant temperature 0.058mm 0.208mm B13 450〇C 5 minutes 450°C constant temperature 0.058mm 0.205mm B21 500°C 0.5 minutes 500°C fixed temperature 0.077mm 0.446mm B22 500°C 2 Minute 500°C Constant temperature 0.076mm 0.404mm B23 500°C 5 minutes 500°C Constant temperature 0.072mm 0.403mm B31 520〇C 0.5 minutes 520°C Constant temperature 0.077mm 0.449mm B32 520〇C 2 minutes 520°C Temperature 0.077mm 0.407mm B33 520〇C 5 minutes 520°C Constant temperature 0.073mm 0.402mm B41 350〇C 0.5 minutes 500°C Constant temperature 0.095mm 0.483mm B42 350〇C 2 minutes 500°C Constant temperature 0.098mm 0.480mm B43 350〇C 5 minutes 500°C Constant temperature 0.095mm 0.478mm B51 250〇C 0.5 minutes 500°C Constant temperature 0.104mm 0.490mm B52 250〇C 2 minutes 500°C Constant temperature 0.108mm 0.488mm B53 250〇C 5 Minute 500 °C constant temperature 0.106mm 0.487mm B61 450〇C 0.5 minutes 450~500 °C warming 0.153mm 0.673mm B62 450〇C 2 minutes 45 0~500°C warming 0.146mm 0.605mm B63 450〇C 5 minutes 450~500°C warming 0.142mm 0.604mm B71 350〇C 0.5 minutes 450~500°C warming 0.163mm 0.689mm B72 350〇C 2 Minute 450~500°C Temperature increase 0.160mm 0.689mm B73 350〇C 5 minutes 450~500°C Warming 0.161mm 0.684mm 22 201008675 B81 350〇C 0.5min 420~500°C Warming 0.176mm 0.802mm B82 350 〇C 2 minutes 420~500°C warming 0.175mm 0.801mm B83 350〇C 5 minutes 420~500°C warming 0.172mm 0.793mm B91 250〇C 0.5min 420~500°C warming 0.189mm 0.845mm B92 250〇C 2 minutes 420~500°C warming 0.188mm 0.845mm B93 250〇C 5 minutes 420~500°C warming 0.181mm 0.838mm In summary, the most important factor affecting the forming performance is the second heat treatment The temperature mode (relative to the constant temperature mode) is preferably implemented by a constant rate temperature increase method, and when the temperature section covers 380 or less or 520 ° C or more, the molding effect is deteriorated, and thus the temperature of the second heat treatment It is preferably between 380 and 52 (TC. In addition, the first heat treatment is lower than the temperature of the second heat treatment temperature (referring to the lowest temperature), the better the molding performance is, but the first heat treatment is lower than 250 ° C, the effect is poor, if it is higher than 450 ° C However, the difference between the molding temperature and the molding temperature cannot be effectively increased, so the first heat treatment is preferably carried out at a constant temperature of 250 to 450 °C. The data from A41, A42, A43, A51, A52, A53 and B41, B42, B43, B51, B52, B53 show that when the temperature of the first heat treatment is significantly lower than the second heat treatment temperature, even if the second heat treatment is Heating at a constant temperature can also produce a better molding performance. Generally, the temperature of the first heat treatment is lower than the second heat treatment temperature by 20 ° C or more to produce a better molding performance. In addition, from Tables 1 and 2, the degree of fineness of the forming performance is approximately 0.01 mm. The present invention can form a magnesium alloy by using the above-mentioned molding method, so that the metal plate 5 can have a relief surface of a number of five or less, and exhibits a fineness of 〇.01 mm, and a second heat treatment in combination with the first heat treatment and the temperature increase mode. , 23 201008675 can also reduce the probability of magnesium alloy fracture during molding, and the molded article 5 produced has the following advantages. (1) High product yield. · Within the above temperature and pressure range, the production yield can be Up to 99% or more; (7) Embossing: Up to five relief surfaces can be formed. (3) High surface quality: The surface of the molded object is smooth and meticulous, and can be used for high-grade surface treatment such as electric ore and anode; (4) High safety: Because the surface of the molded object is smooth and fine, it is not necessary to grind to avoid the generation of flammable magnesium chips. (5) Single-die molding: the use of the master mold without a male mold, easy to open the mold, and (6) easy to demould: workpiece Direct contact with the demoulding device to cool the workpiece after shrinking and directly attached to the demoulding device for demoulding, the mold does not need lubricant or release agent; © (7) Large-area molding: molding area up to 5〇〇mmx 5〇〇mm Molding a secondary molded article can be obtained a large amount, the production speed. In summary, in the molding method of the present invention, the fluid is pressurized by the master mold base 2 and the seal mold 3, and the two-stage first heat treatment and the second heat treatment are combined to form the metal sheet 5, and then the cutter is removed. The mold 73 cuts the formed metal sheet 5 into a molded article 5'' and shrinks the molded article 5 by shrinking, attaches it to the stripping module 72, and removes it to release the mold, so that the metal sheet 5 can have five The following relief surface, and exhibiting a fineness of 〇〇lmm, can indeed achieve the object of the present invention. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
