Design Stage, Mass Pro and Test

Proposal Stage



Rendering/ styling concept proposal submit to customer.Normally proposal 3 design.Each design from difference theme.Customer will select 1 from 3 design. Custermer will choose the material depend of the budget and volume.


1. RRIM (suitable For High Volume)
2. FRP.(suitable For Low Volume)

RRIM Introduction.

Reaction Injection Molding (RIM) is read more


FRP Introdution.

Known as fiber reinforce plastic read more


For Design review have to option.
  1. prototype (milling by CNC machine)
  2. Clay/ Hard modelling.
For the item no. 1 the cost very exspansive. For the medium company normally choose option no. 2 if the have in house modelling.

For the Clay/ Hard modelling, its will take 3 to 4 week to complete the whole body kit. But the process more enjoyable we can play around with the clay. Some time rendering fake but not the clay we can feel the design and touch the styling.




Top images show the modeller patch the clay to the car body until the certain high archive depend of the styling.Bottom view the modeller sculpting or shaping the clay guide by designer and rendering image.



below the clay +resin complete with base colour ready to review with customer



After customer agree we move to next step mould fabrication.

RRIM Mould Design Stage.


We need to scan the prototype to genarate 3D data. On this stage cad designer will design class A surface and ED (engineering design).




Image below shown digitizing data(cloud of point). Cad designer will generate the surface and cloud of point as a guide.Image no.2 shown line intersection between C.O.P with plane. Rough surface already seen. In this stage mounting strategy will counting into the design.



After completion Cad designer assembly all part to body vehicle and review with team and customer after all team agree, all 3d data will sent to mould maker to fabricate mould.



Sample rear skirt mould images.







Image below shown the front skirt after demould after this the part need 3 days curing process before sent to painting.




After painting we assembly the part to the vehicle and final review with customer. below images shown the part fitting with the vehicle.



Avery automotive manufacturer have their own spec but almost 70% are same. As a vendor to fulfill their requirement is must. This body kit need to run the test before can sale. They test are,

  1. humidity test.
  2. endurance test 25000km.
  3. heat thermal test.
  4. wet out test and and etc.
After the test pass the car with full body kit will launch. This video shown slam test for the rear spoiler. The test run 70,000 slam if the spoiler detach that consider fail
