auto trim molding

Door trim can be divided into four types: left front trim, right front trim, left back trim, right back trim. As to the material , we often mainly use PP+EPDM-T20, Because of the assembly , the size

requirement of trim injection mould is very strict. For example, product surface isn’t allowed welding line, not allowed pin mark and have high requirement about the strength and flash not allowed.

Door trim mould steel material is usually 718H. And door trim mould tooling time is about 60days. The mould flow will use side fan-shaped gate. Because auto trim mould is interior parts mould, the function requirement is also very strict. We would test the product by smell, inflaming retarding, aging resistant, anti-seismic, low temperature, high temperature and scrape resistance ect.

As the mould structure:

Firstly, mould structure conclude hot runner protect guide pin, located ring, clamping block, pry pit, support plate, eye bolt and cooling line.

Secondly, mould base requirement as follows:

1.      hot runner guide pin should be 20mm higher than the nozzle to protect the mould when assembly.

2.     Two pry pit should have a certain space

3.     Support plate should be set.

Mould design:

1) Auto plastic mould design is a brain demanding work which has no copy action.

2) When designing a auto plastic injection mould the method of modification should be taken into consideration and should have enough space for modification.

3) The devices of the auto plastic part injection mould should meet the standard of anti-grating and long-life shots.

4) The manufacturing skill and time is different with the hardness and stretchiness of the material.

5) Because of its precision, most of work has to be done by manual work.

6) Plastic auto plastic injection mould of high quality should be qualified with good surface manufacturing and precision
