China quality molds and products supplier selection

Luxury sports car maker Aston Martin has announced a global recall

Aston Martin ignore its internal processes for a range of procurement, vendor and product monitoring problems,since November 2007 produced a total of 17,590 sports car, called the discovery of parts of China for the production of sub-suppliers in Shenzhen KEXIANG mold companies（Shenzhen KeXiang Mould Tool Co Limited） use fake plastic material. In this regard, caught in storm in Shenzhen KEXIANG mold company responsible Ang Zhang announced that denies its production Aston Martin • Over parts. China has a lot of plastic injection molds and products manufacturer, they serve different target customers, some companies large scale, but the basic outsourcing, in fact, customers need to find is a real experience, and provide long-term senior custom mold for overseas customers and plastic products suppliers, CN-MOULDING no doubt that customers really need to find manufacturers.Since its establishment in 1997, the years from different companies for their commitment to providing quality automotive parts, medical equipment, industrial supplies, electronic components, small appliances mold design and manufacture of lastic products processing factories. The company currently employs 80 people,The significance of the quality of the enterprise:

Quality control for plastic injection molding in china

Parts made in a plastic injection molding process can have their own unique set of possible defects. That is why all of our employees are trained to spot these problems. The following is a listing of the most common defects associated with the plastic injection molding and transfer/compression molding processes:

Sink Marks: Sinking is caused by the outer skin of plastic solidifying while the material inside is still molten and viscous. As it cools and solidifies, the material compacts . The best way to avoid these dimples is to design the part with a consistent wall thickness. However, many times the effect of the sink mark can be minimized by adjusting molding parameters such as injection pressure and time.

Gas marks (burning): When molten plastic is injected into a mold cavity, the air that is in that cavity needs a place to escape. If the hot compressed air cannot escape, it may leave burn mark on the part. The best way to avoid gas marks is to strategically locate air vents of the proper depth within the mold. Adjustments to process parameters such as injection speed and screw speed can be altered to reduce or eliminate burning.
