It is appropriate to use high material temperature, high mold temperature, low injection pressure, extended injection time is conducive to reducing internal stress, to prevent shrinkage.

 
2. It is appropriate to use high material temperature, high mold temperature, low injection pressure, extended injection time is conducive to reducing internal stress, to prevent shrinkage. Deformation. 3. Available in various forms gate, gate and plastic parts arc connection, so as not to Plastic parts thickness uniformity, preferably without inserts, if the inserts should be preheated. Plastic products are made of what raw materials of plastic is a synthetic resin and filler, plasticizers, stabilizers, lubricants, colorants and other additives composed of polymer materials, its main component is a synthetic resin. In this case,
Resin is the term originally derived from animal and plant lipid named, such as rosin, shellac, etc., the current resin is not yet mixed with a variety of additives, polymer raw materials. Resin accounts for about 40% of the total weight of plastic to 100%. The basic properties of plastic mainly depends on the nature of the resin, but additives also play an important role. In this case,
Some plastics are basically composed of synthetic resin, with or without additives, such as plexiglass, polystyrene, PC and so on. Therefore, the two terms plastic and resin are sometimes mixed, but generally there are differences. In this case,
Classification of plastics
According to the structure and shape of resin after heat change, can be divided into:
(1) thermosetting plastic (resin): refers to the heat, pressure or in the curing agent, ultraviolet light under the action of chemical reaction, crosslinking curing insoluble material into a large class of synthetic resin. In this case,
(2) thermoplastic (resin): linear structure (including branched structure) polymer composition, due to the existence of independent molecules, it is elastic, plasticity, can dissolve in the solvent, heating can melt, hardness and brittleness Smaller features. In this case,

Thermosetting plastics - Characteristics
In the early development of the plastics industry, thermosetting resin accounts for a large proportion, generally more than 50%. In this case,
With the development of petrochemical industry, thermoplastic resin production increased dramatically, to 80 years, thermosetting resin in the world total output of synthetic resin accounted for only 10% to 20%.
