Injection Plastic Products Mold process description

Numbering Specific matters Detailed description
1 Selection of mold steel mold steel: 45#, 50#, P20, H13, 718, 2738, NAK 80, S136, SKD61, etc.

This type of product is a type with high appearance requirements, and the surface of the product requires high brightness, so the choice of mold material is very important, but considering the price, generally choose P20 steel, P20 is pre-hardened steel, not suitable for heat treatment , But can be nitrided, hardness 280HRC~400, because it has been pre-hardened, mechanical cutting is not difficult, and the hardness of this steel is higher than that of medium carbon steel, the deformation is also more stable than medium carbon steel, so in plastic mold It is widely adopted.

2 Formwork LKM, HASCO, etc.
3 Design software UG, PROE, CAD, CAXA, etc.
4 Plastic material PP, PC, PS, PE, PU, PVC, ABS, PMMA, etc.
5 Design of mold structure A professional designer designs a reasonable structure for you to achieve the shortest production cycle and reduce the follow-up processing procedures to improve production efficiency.

Cold runner, hot runner and hot nozzle cold runner structures are the three most commonly used.

6 Cooling water system and gate design According to the product’s structural characteristics and product appearance requirements to design a reasonable gate form, there are

Large gate, latent gate and fan gate, needle valve type, etc., reasonable cooling system

The mold temperature can be balanced in the shortest time to improve the accuracy and accuracy of the product

Product production efficiency.

7 Parts configuration Inserts, guide columns, guide sleeves, sliders, slider sleeves, inclined top blocks, etc. adopt wear-resistant standards

Parts to increase the service life of the mold.

8 Cavity Single/Double/Multiple
9 Mold surface treatment Industrial polishing grade
10 Product mold time 6-90 seconds
11 Target mold life 500,000 times or more
12 Time required to complete the mold 25-70 days
