How to Make a Plastic Injection Mould

To make a Plastic injection mould, Firstly we use Pro/Engineer、UG、Solidworks、AutoCAD software to make the Product drawing and mould design. After get the confirmation from Customer, The Plastic injection mould steel will be ordered, Widely used Mould steel as follows:
DIN 1.2311 (HRC31-35)
H13(HRC48-55)
DIN 1.2344 (HRC48-55)
DIN 1.2083 (HRC45)
DIN 1.2738(HRC35-38)
DIN 1.2316(HRC45-52),STAINLESS
Pre-hardened P20 (HRC29-33)
Pre-hardened 718(HRC33-36)
Plastic Injection Mould Machining: The general process involved is square cutting, CNC, Drilling, heat treatment(quenching, tempering), Engraving, Grinding machine, lathe machine, EDM, Wire cutting, Laser Engraving, surface treatment, assembly
1. Heat treatment
In the heat treatment process of Plastic injection mould, it is necessary to control the internal stress while obtaining the required hardness to ensure the dimensional stability of parts during processing
2. Grinding Process
There are three main types of grinding machines: Surface grinder, internal and external cylindrical grinder and tool grinder. During finishing grinding, grinding deformation and the generation of grinding cracks should be strictly controlled. Therefore, the fine grinding feed should be small, the coolant should be sufficient, the size tolerance within 0.01mm Plastic injection mould part should be constant temperature grinding.

Plastic industry is increasingly important,Become the important symbolto of measure a country levels of product manufacturing, there will be no high level of product if don't have high levels of mold. SINOMOULD company is famous for plastic mold manufacturing, professional for custom high precision plastic mold.

plastic mold classification

   1 Generally, mold can be divided into larger, medium and small molds according to the size, divided into a large number, batch and single-piece batch according to production quantities; accordance with the accuracy requirements can be divided into high accuracy, middle precision and low accuracy.

   2 according to the different methods of molding and mold construction, mold can be divided into two categories: one is the through mold, including stamping mold, drawing mold, extrusion die, etc.; Another is mold cavity, including bending mold,etc

how to choose mold production companies?
