Mold Select Edit

Blister packaging mold generally have gypsum mold, electroplating copper mold and aluminum mold three

Gypsum mold: gypsum in the semi-wet state carving molding, and then dried into a mold, gypsum mold cost is low, easy to modify, but the gypsum mold accuracy is not high enough, the surface is not smooth and fragile and durable, so it is often used to fight Pretend to do the copper mold or some of the requirements of the production of plastic mold is not high or small.

Aluminum mold: with aluminum ingots through machinery (lathes, milling machines, CNC, etc.) from processing. Aluminum mold high precision, the surface is smooth and durable, but the price is very expensive, aluminum mold is generally used in the accuracy of the higher copper mold can not reach the plastic products.

Plating copper mold: made of gypsum made of samples, the electroplating of a layer of copper shell is the electroplating copper mold, the cost is relatively high gypsum mold, but much cheaper than the aluminum die, because of its smooth and durable surface, low cost advantages, Copper mold is the most commonly used plastic mold.

Terminology nouns

Blister: a plastic processing technology, the main principle is to flatten the plastic hard sheet softened, the use of vacuum adsorption on the mold surface, after cooling molding, widely used in plastic packaging, lighting, advertising, decoration and other industries.

Blister packaging: the use of plastic production process to produce plastic products, and the corresponding equipment to the product of the general name of the package. Blister packaging products include: blister, tray, plastic box, synonyms are: vacuum hood, blister and so on. Blister packaging equipment include: plastic molding machine, punch, sealing machine, high frequency machine, folding machine.

Blister: Blister plastic transparent film made of a specific shape of the transparent plastic transparent cover, cover the product surface, play a protective and beautify the role of the product. Also known as blister, vacuum hood.

Tray: also known as plastic inner care, the use of plastic technology will be made of plastic hard film into a specific groove of plastic, the product placed in the groove, play a protective and beautify the role of the product.

Flocking care: is a special material of the plastic tray, the ordinary plastic hard film surface attached to a layer of velvet material, so that the tray surface a kind of fluffy feel, used to improve the packaging grade.

Antistatic tray: is a special material of the plastic tray, the material surface resistance is less than 10 of the 11th power ohm. Mainly used for electronic, IT products, plastic tray.

Blister mold: Blister production mold, the lowest cost is gypsum mold, followed by electroplating copper mold, the most expensive is the aluminum mold. The mold is drilled with small holes for vacuum adsorption of heat hardened to form a blister product.

Blister molding: We often talk about the plastic, the use of plastic molding machine will heat softening of the plastic hard film adsorption on the mold surface, after cooling, the formation of concave and convex shape of the plastic.

Blister cutting: plastic plastic products after molding, through the punch, the large sheet of paper with a knife die into a single product.

Folding: Blister packaging is called a card packaging, the need for the three sides of the blister with a folding machine folded to the back, so that in the next packaging process, the paper card inserted into the fold, the formation of card packaging The

Heat sealing: is a blister packaging process, with a sealing machine will be coated with plastic oil on the surface of the card and the bubble together, the formation of suction card packaging.

High-frequency sealing: is a blister packaging process, with high frequency machine to produce high frequency, the bubble shell and foam between the bonded together to form a double bubble shell packaging.

Ultrasonic sealing: is a blister packaging process, the use of ultrasonic machines produce ultrasound, the bubble shell and foam shell together, the formation of double bubble shell packaging, and high-frequency sealing is different, the ultrasonic not only can seal PVC, PETG Materials, PET materials can also be sealed, but also the packaging of products without electromagnetic damage, especially for electronic products, packaging; the inadequacies of the ultrasonic edge can only be separated from the point-like, and generally only one straight edge.

Quality Q & A

What is the crystal point? How to solve the problem?

Crystal point is a point on the plastic packaging materials, will seriously affect the appearance of blister packaging products, quality problems are from the sheet suppliers, the reason is that the production of the sheet, there are debris mixed In the material, there will be such a quality situation, the solution is to produce plastic packaging products before the inspection of the sheet.

How is the uneven thickness caused? How to solve such a problem?

Thickness unevenness has the most common points, shelves, sheet, temperature and so on. Shelves in the compression plastic packaging products when the location of the adjustment is very critical, if there is dislocation or placed unreasonable phenomenon, there will be uneven thickness. And the sheet is related to the sheet in the production process which did not adjust the thickness, so it will lead to such a quality problem. Temperature debugging is also directly related, but also according to different molds of different materials to adjust the level of the corresponding temperature, otherwise there is a non-uniform phenomenon. The solution is to pay attention to the position adjustment of the shelves, the condition of the supplier consultation, the temperature adjusted to the sheet and the mold fit.

What is the pull line? How did How to solve?

Pull line is the edge of the product will appear to highlight the line of a serious impact on the appearance of the packaging, resulting in the reasons for the formation of such a situation with the plastic mold manufacturing structure, the control of the plastic molding machine operation, Temperature adjustment, shelves have a great relationship, the solution is the mold quality control, machine and temperature parameter adjustment, shelves and so on.

What is water ripple and bubble? How did How to solve?

Water ripples and bubbles are the surface of the material watermark and bubble point, so that the plastic products will directly affect the appearance of packaging items, reducing the appearance of the packaging image. Water ripple is the relationship between the sheet business sheet In the production process, there is water ripple is the speed of the film when there is a relationship. The reason for the bubble is that the temperature of the sheet is too high or the mixed production of the sheet causes the sheet to be infiltrated into the air. The presence of the bubble material causes the perforated and deformed plastic products to become defective Method is to purchase the material back or before production must be observed before the quality of the sheet before storage or production.

What is scratches? How does this quality problem lead to? How to solve?

Scratch is the production of plastic products will appear after the appearance of scraping, but also the quality of the often problems, the reason is because in the production process, the manual process more prone to friction, punch personnel and packaging staff The mode of operation is the most critical link. The solution is to carefully handle the product, keep the table clean, the staff wearing gloves and other related matters, but also can effectively prevent the occurrence of scratches, plastic packaging products, more manual processes, so in the Each link must be closely watched in order to avoid the occurrence of defective.
