Two-shot molding trends: one based on the use of different features, such as thick pieces of finished material with a soft skin material, the core material using a hard material or plastic foam core material can be used to reduce weight. 2 may use lower-quality core material in order to reduce costs. 3 cortical material or core material can be expensive to use and possessed a special surface properties, such as anti-electromagnetic interference, high conductivity and other materials to increase product performance. 4 proper skin material and core material combinations can reduce the residual stress moldings, increase the mechanical strength or surface properties of the product. 5 produces products such as marble texture. Belonging to the plastics processing industry is the chemical category, this period to be exposed to many chemicals, such as: plastic working of stabilizers, colorants, curing agents! Add these things would certainly produce some of the more unpleasant odor. Plastics processing process which is inseparable from the water, and will generate a lot of business waste during this period. So if it is not a plastic processing enterprise set of environmental treatment equipment, then! Air and water it produces is bound to cause great harm to the surrounding areas. Therefore, the Government requires plastic processing plants must be built in a residential area away from the more remote areas of injection molding plant, environmental protection department of this requirement is very strict. Second, the choice of plastic processing plants must be ventilated good location, it is a good exhaust missed timely exclusion Kunshan injection molding, rather than gather in one area, eventually causing environmental pollution incidents. Plastic processing plant location must be relatively far away from the river, once the wastewater flowing rivers which then cause significant pollution of the environment which will lower river region. While the future of the market for all kinds of plastic injection molding products, plastic extrusion products, plastic products, such as compression molding demand is strong, but the current state of the government crackdown on corporate pollution is still relatively strong, which also includes plastics processing enterprises. So plastics processing companies in order to obtain long-term development, we must comply with national environmental policy related to the construction of the plant and in the choice of the time, more than refer to a number of factors.
