Tooling Development

Gear Tooling Design

Tooling design of gear is different from traditional mold design,it need actual experience data to adjust the gear tooth thickness, modulus, pressure angle, also the tooling manufacture can not based on the theory shrinkage rate of material directly, our advantages are:

On the basis of KISSSOFT, we independently developed the parametric calculation software of plastic gear mold cavity according to our working experience. The software can create the model of gear profile and modify the gear shape to enhance the pricision of gear profile .

After the gear model created by the software , it can be used to machine manufucture by the wire cutting and EDM , so that the precision of tooling fabrication is enhanced.

Gearbox Design Platform

Mold Flow Analysis

2 mold flow analysisers with 8 years working experience on material reseach and have postgraduate diploma .

Can accurately predict the product deformation, shrinkage, position of material lack, air trapped and other defects, also give the corresponding solutions .

Can compare the different tooling desgin and choose a best option；

Optimize the molding parameters to enhance the efficiency of tooling pilot injection .

Mold Flow Analysis

Gearbox Design

Gearbox Design Platform

Our gearbox design platform is a patent in ZhaoWei Compnay, it can create the precise model of planetary gear system with involute 、bevel gear 、spur gear etc.by the parameter calculation automatically. The advantage of this platform is combinated with the idea design, structure design, gear shape design and mold flow analysis etc.

The platform of gearbox design has obviously characters on the reasonable distribution of modified coefficient ,optimization of meshing angle,slip rate and coincidence area verification . Also, it has excellent advantages in interference analysis, improvement of gearbox working efficience, noise, working life etc.complex technical problems .

Gearbox Design Platform

Dynamic Simulation and Finite Element Analysis

In the design stage of gear and gearbox, use kinematic simulation to analyse and verify rotation situation and interference position. Also, use the finite element analysis technology and ANSYS Multiphysics module to analyse and verify the tooth surface strength of the arc gear and bevel gear in order to ensure the reliability of product .

Dynamic Simulation and Finite Element Analysis
