Quality First，Service Best

Our team

We are a dynamic and responsible team. We have a professional factory with design, development, testing experience and ability, responsible for the entire production process, to meet a number of conceptual design requirements, so that customers enjoy the quality of high-end series.
We have professional technical department, skilled production department, and experienced QC department to ensure that every product is qualified after completion and can be shipped to our customers.
At the same time, we have a professional sales team to provide customers with timely and accurate quotes, product measurement and confirmation, feedback in the production process, on-time delivery and after-sales support. All these measures will ensure that customers can place the order without any worries from our company.

Enterprise Advantage

Certification: SGS Verified, IATF16949 certification

Rubber Formula Design

We design the perfect rubber formula for match the different requirement. Engineer team with 20+ years of design experience, combined with professional rubber processing team, assists in the development of high-performance, low-cost rubber shock absorption products.

Tooling Design

We have always believed that the process control of products is more than simple dimensional control. Tooling design will have a great impact on the products. The rich design experience combined with the finite element analysis makes our design more handy.

Metal Skeleton Machining

With strong metal processing capabilities, it can quickly respond to customers' requirements for sample delivery and trial production. Carrying out internal quality control of the metal skeleton helps to reduce defective products in the vulcanization process, reduce the risk of mold damage, and ensure delivery and quality.

100% Verification

In the process design stage, we identify the customer's assembly dimensions and design the critical control points. For example: 100% full inspection of the inner diameter of the vulcanized product, etc., will minimize the possibility of problems affecting the customer's assembly.

Durability Test

The testing which we need to do is depends on the working condition, we need INPUT from customer.
For example, the common fatigue test for leaf spring bushing is:
- Radial load + torsional angle， frequency 1-3Hz
