Plastic Container Moulding Machine

ZOWEITE® Plastic container moulding machine molded containers made in China can be straight sided or tapered, narrow or wide mouth shapes such as boxes, jars, tubs and vials. Material is injected into a cavity where pressure forces the resin to conform to the mold body. Containers are capable of holding to a tighter dimensional tolerance, and are more uniform in wall distribution. A wide variety of resins can be processed via the Plastic container moulding machine process, the most popular being polypropylene, styrene and polyethylene.

Plastic manufacturing process play an important role to re-cycled waste Plastics materials. Plastic containers are very useful for packaging to various industries. Cosmetics packaging requires plastic jars for make-up products and skincare products. Plastic bottles are used for Pharmaceutical packaging to hold vitamins, tablets, capsules and other medicines. Food and beverage packaging also include use of all sorts of plastic containers, such as plastic bottles for water,milk bottles and plastic jars for use as deli containers. Therefore the importance of plastic packaging has been increased day by day.

What are difference between Plastic container moulding machine and blow molding machine?

● The process of Plastic container moulding machine is different from that of blow molding machine. Blow molding is injection + blow; Plastic container moulding machine is injection + pressure; Blow molding must have the head left by pulling out the blow pipe, and injection molding must have gate section

● Generally speaking, Plastic container moulding machine is a solid core, blow molding is an empty core, and the blow molding surface is uneven. Blow molding has a blow port

● Different raw materials

Plastic container moulding machine : the raw materials for injection molding are usually thermoplastic or thermosetting materials.

Blow molding: the raw materials for blow molding are usually polyethylene, polyvinyl chloride, polypropylene, polystyrene, thermoplastic polyester, polycarbonate, polyamide, cellulose acetate and polyacetal resin, among which polyethylene is the most widely used.

● Plastic container moulding machine , that is, thermoplastic injection molding, this method is to melt the plastic material and then inject it into the membrane cavity. Once the molten plastic enters the mold, it is cooled and formed into a certain shape according to the mold cavity. The resulting shape is often the final product, and no other processing is required before installation or use as the final product. Many details, such as protrusions, ribs and threads, can be formed in one step of injection molding. The injection molding machine has two basic components: an injection device and a clamping device for melting and feeding plastic into the mold.

● Blow molding: also known as hollow blow molding, a rapidly developing plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in the split mold while it is hot (or heated to a softened state). After the mold is closed, compressed air is immediately introduced into the parison to make the plastic parison expand and cling to the inner wall of the mold. After cooling and demoulding, various hollow products are obtained. The manufacturing process of blown film is very similar to that of hollow products in principle, but it does not use molds. From the perspective of plastic processing technology classification, the molding process of blown film is usually included in extrusion.
