Door Panel Tooling

This tail gate tooling costs about 1 million RMB and will bring over 8 million RMB sales volume by estimation. As it is introduced to many other car makers, significant economic benefits will be created for both tool makers and component suppliers.

Using P/E-I-TD30 to partially replace sheet metal makes the tail gate trim assembly a higher integration level and more possibilities for design. It does not only reduce product weight, but also has the production tact time and developing cost saved. Let’s see the sum-ups bellow:

1 Total weight of vehicle is reduced so that the production cost has been saved.

2 More design elements can be applied making it a highlight, furthermore, the product design and molding process with the door panel molding tool are optimized.

3 A great resilience for saving vehicle utility cost.

4 The energy absorbing function of the material eases damage caused by collision.

5 To improve fluency at both sides by design to decrease wind resistance and vehicle rear part pressure taken so that the energy consumption can be reduced.

Key Technology Index

1 For appearance design improved from simple to various styles e.g. the pulling-through flow LED tail lamp.

2 Weight reduced without performance index reduced.

Product Standard

1 Strength is not decreased from sheet metal door panel that the product thickness is increased and enhancing ribs are added properly.

2 By increasing SM tapes and applying flannelette at connecting area between plastic part and sheet metal, the abnormal sound and vibration can be eliminated.

3 Sound insulation effect is better than traditional one.

Technology Maturity

Based on TRL technology maturity theory, this solution has reached level of TRL9.

Industrialization Present Status

1 The product has been used at JMC Ford Equator, calculated by 80 thousand copies made by our door panel tooling per year, the parts supplier will have sales volume over $1.25 million yearly. And as this solution is widely introduced, the lightweight applying range of complete vehicle is expanded and economic benefits are significantly created.

2 Such case of lightweight product design and renovation brings our tool room reputation, giant market potential and profit growth engine, moreover, gets company and Tier 1 suppliers competition enhanced.
