. –After that the part may continue to shrink very slightly for several hours or even days until the temperature and moisture content stabilize. Thus dimensional inspection should wait at least a day. The production technique used within our company to manufacture of plastic products is injection molding.
What exactly is plastic injection molding? Injection molding is the ideal production for many ( daily) items. In everyday life, almost everyone has always different injection molded products within his or her reach.
Injection molding works as follows: It begins with the production or manufacturing of a die (mold, tool) this is a piece of steel (or aluminum) which consists of two halves, so that these can away move linear from one to another. In this mold, the mold made of the product. If this is done then the mold can be placed in an injection molding machine to fabricate the plastic products. The different types of granules (plastic pellets) to be heated to about 260 ° C. This creates a liquid substance, with which the mold is fully injected under high pressure, so that the product gets its shape.
Advance the desired dyes are added. During injection molding, the two mold halves are held against one another with force, in china , with our machines, that can be that up to 650 tonnes. Immediately after, the product is cooled in the mold, after which the mold can be opened and the product ejected.
The product is then ready to be ejected. From the supplied raw material to the final product that is delivered to you, our factories guarantees a good quality. A good logistic organization ensures high efficiency during production and at our episodes.
Injection molding Injection molding is a shaping technique for thermoplastics, thermosets and metal having a low melting point. In particular, this concerns thermoplastics. With injection molding, plastic material that is supplied as a granulate or powder, melted to a viscous mass and is injected under high pressure into a mold, the cavity (or cavity) is the form of the desired product. By cooling the plastic material solidifies and one gets the desired product.
Injection molding is one of the most widely used design techniques for plastic parts. The art of plastic injection molding. This art mastered by united Plastic group like no other.

Articles; what causes shrinkage of plastic materials: What is shrinkage ? •Shrinkage is the contraction of the molded part as it cools after injection. Most of the plastics we know shrink in the mold during cooling , some shrink after they ejected the parts out of the cavity. –After that the part can continue to shrink ( small percentages) for a few hours or even days until the temperature and moisture content stabilize. Thus dimensional inspection should wait at least a day....
shrinkage of plastic material depends on different factors; We describe 4 here under:
What does shrinkage do after the injection molding of thermoplastics?
In the injection molding of thermoplastic materials, it is possible to obtain a molded product with the desired dimensions.
Dimensional Shrinkage is the phenomenon in which the volume of the molten plastic material that is filled in shrinks the mold cavity, is smaller, at the moment that is cooled during solidification.
