1. Tooling and Equipment for Automotive Interior Trims
R&D including: 3D modeling, forming tooling and process, punching and water cutting, special checking fixture, special equipment for automotive interior trims. These tooling and equipment have been equipped on many popular vehicles.
1.1 3D Modeling
It can create accurate geometry and spatial location of every hole, every bump, every ridge and each piece surface of automotive interior parts, therefore, to reach the perfect fit with car body and other related parts, and to achieve a smooth, comfortable and pleasant inner space. The technology has been used in design and manufacturing front floor carpet, rear carpet, headliner Trunk Trim，Trunk Lid，Pad ASSY，Pad-Hood，wheel fender，Door Panel，Chair Cushion，Heat and Sound Insulating Felt etc.
1.2 Automotive Interior Forming Process and Tooling
According to the material and shape, rational tooling structure, loading and unloading system, floating or fixed blank pressing device can be designed and manufactured, which is convenient for tooling changing and connecting with press.
Thermoplastic forming tooling has built-in water cooling device, rapid self-closing joints. Thermoset forming tooling, by adopting rigid and large section contacted design, can realize high efficient heat transfer.
High density aluminum casting mold blank has no sand holes, no pores, and other casting defects. High heat transfer efficiency improves productivity. Stainless materials avoid grease contamination to soft decoration materials.
Mold cavity is made by precision CNC machining with high accuracy and smooth surface.
According to forming temperature, setting time, geometry shape, blank pressing method, material properties and so on, the correct product shrinkage ratio is determined by experiments.

1.3 Punching and water cutting Toolings
Punching tooling:Hot and cold stamping tooling——heterotypic hole and three-dimensional curve cutting, serrated edge, cutting in any direction, multiple movements, automatic return of material, automatic temperature control (hot cutting).
Water cutting tooling——complex cavity positioning, negative pressure dehydration, all stainless material, with trimming and punching functions.
1.4 Automotive interior special checking fixture
Made by special material, removable. Accuracy guarantees by triple-coordinate measuring. Car coordinate and tolerance is colorfully identified. Pins or fitting positioning. Surface brightness.
1.5 Automotive Interior Special Equipment
Far-infrared radiation and contact heating furnace; hydraulic or pneumatic special press, flexible water-cutting system, material transfer; online automatic control. We can provide design and manufacture of single equipment or production line.
