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....
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,...
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...
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...
(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...
What is EDM ?
The Electrical Discharge Machining Machine(EDM for short) is a kind of mechanical processing machines mainly used for electrical discharge machining. Widely used in the manufacturing of various metal molds and mechanical equipment, it is a special processing method for removing conductive materials by electro-erosion caused by pulse discharges between...
