Plastic mold , refers to the mold used in plastic production, the lowest cost is a plaster mold, followed by electroplated copper mold, the most expensive is aluminum mold. The mold is drilled with small holes for the vacuum adsorption of the heated hard sheet to form a plastic product.

1, plaster mold, plastic mold

The plaster mold is mainly made of yellow plastic hand gypsum powder; if drawings are provided, the gypsum material will be finished by milling machine and handwork according to the drawing data and requirements; if the physical object is provided, the real material shall be finished with manual mud first. Contour, vacuum formed into a vacuum cover, and then come back plaster mold, and modify the mold to complete; take about 2-4 days; plaster mold easy production, shorter time, is conducive to product packaging changes, the price is lower, but The durability is low. After being used for a period of time, it is relatively easy to be damaged and the transparency of the produced product is poor. It is mainly applicable to products whose first board is confirmed and whose transparency is not required in the packaging.

Plastic mold is usually in accordance with product design requirements, made of plaster mold, using a vacuum mold to produce a vacuum cover, with a special high-temperature resin material, into the vacuum cover, until the mold is dry, drilling, grinding is completed; It takes 3-5 days; the cost of resin molds is higher than that of copper molds and plasters, but its use is comparable to that of copper molds. It is more durable and can solve some technical problems that copper molds and gypsum molds cannot handle, such as the appearance of water lines on product walls. , With such a mold can have better results; mainly applicable to electronics, toys, medicine, food, automotive products ... ... and other special requirements of the product.

2, wooden model

It adopts imported heat-generating materials, Nissan high-temperature tape and high-quality copper nails to produce all kinds of bakelite molds, featuring uniform heat generation and good sealing effect. It can be applied to all kinds of disc machines, Taiwan push-pull machines and automatic chain machines. Main applications Heat sealing packaging for paper cards and blister packs.

3, electrolytic copper mold

According to product design requirements, after the plaster mold is made, a vacuum cover is produced using a plaster mold, the vacuum cover is placed in an electrolytic cylinder, and when the surface is 5-8 mm thick, the mold is injected into the plaster, the vacuum air hole is injected, and the mold surface is polished Smooth, ready to use; takes about 3-5 days; is a metal mold, so it is more durable, the appearance and transparency of the products produced with this type of mold is better; the mold is cheaper to produce and uses more widely, is the usual situation The preferred mold; mainly applicable to electronics, toys, stationery, cosmetics, automotive products ... ... and other demanding products.

4, alloy aluminum mold

According to the provided drawings or templates, the program is programmed by CAM or other programming software, and the machining is completed by the CNC machine tool. Then other holes such as air holes and undercut positions are manually made and the mold can be polished smoothly. Special requirements also need to spray Teflon or sandblasting. Made of aluminum materials such as ZL401, 6061 and 7075, this type of mold has high precision, and the products produced are more beautiful in contour and angle, and the durability is very high. The price is also the first of four types of molds; , Gifts, toys, medicines, stationery, etc. The products with higher appearance and size requirements; In fact, the alloy aluminum mold is the preferred mold for high-volume and high-demand blister production, compared with plaster molds, copper molds, and plastic molds. Durable, time saving, high production efficiency and low scrap rate.

5, heat sealing mold

The heat sealing mold adopts high-quality copper or alloy aluminum, which is mainly used for the problem of PET high-frequency heat sealing; the surface treatment adopts Teflon, and it is used for PET sticking; the pressing pattern is computer-engraved, the pattern is clear, the size is uniform, and can be according to user requirements. Customize various patterns.

6, high frequency mold

The high-frequency mould material is a high-quality pressure wire, the cutter is a laser knife, and the trimming edge is smooth and without any burr edge tearing material; the edge trimming pattern is computer-engraved, the texture is clear, the size is uniform, and various patterns can be customized according to the requirements of the user; It can be made on the basis of customer samples or drawings; it is mainly used for welding of double-bubble shells (PVC or PETG).

7, knife die, punching die

Mainly used for punching and punching (round hole, aircraft hole and butterfly hole)

Note: Regardless of die cutters and punching dies, the molds used for blister production are the lowest cost plaster casts, followed by electroplated copper dies, and the most expensive are aluminum dies. The mold is drilled with small holes for the vacuum adsorption of the heated hard sheet to form a plastic product.
