The Principal of Plastic Injection Moulding The so-called plastic injection moulding process refers to: the plastic material in the barrel of an injection molding machine is plasticized into a melt by the sheer heat that is generated by external heating and screw rotation, and then the melt is fed into the cavity of...
Gate Design Considerations: 1.Injection molding gate is a small opening between the runners and the mold cavity. their location, quantity, shape and size, etc. have a great influence on product appearance, dimensional , physical characteristics and production efficiency. 2.The gate size is dependent on product weight, material and gate types....
plastic resin material
In today's market, there are tons of material for customer to choose from. Therefore, The selection process of plastic injection molding material is very challenging at the beginning. At ECO Molding, we are well aware that each plastic material has its unique characteristics and advantages,...
ABS Injection molding parts
I. Injection Mold 1. If the mold cavity is not appropriately processed, such as the appearance of scratches, micropores, abrasion and roughness, it will inevitably reflect on the plastic products, so that the glossiness of the plastic product will not be satisfactory. In this case, the mold should be carefully processed to allow the...
PC+ABS plastic resin
What is the PC+ABS material? What are the purposes of PC+ABS? And, what is the injection molding process of it? PC plastic is a new type of thermoplastic with a transparency of 90%, and is thus dubbed a transparent metal. It is rigid and tough, possesses high impact strength and high...
Definition: WEDM-LS refers to a CNC machine that uses a continuous moving thin metal wire (referred to as EDM wire, usually made of copper or molybdenum) as an electrode to perform spark discharge on a workpiece, which produces a temperature as high as 6000+ degrees, and erodes the metal to create a workpiece...
flow mark injection molding defect
(1) What is  flow mark (appearance)? Flow mark refers to the wavy lines or patterns appearing on the surface of the molded product. This usually happens when the injection speed is slow, or when the surface layer solidifies faster than resin filling Fig. 1: Flow mark on the surface of a...
