| Project | General Processing Plant | Chengxin Sealing King Precision Injection Molding PI Team |
|---|---|---|
| Intervention phase | Most only accept finalized drawings and molds. | We can get involved from the design and material selection stages to assist with adjustments. |
| Key points | Produce to order, execute based on current conditions | Focus on "mass-producibility" and "long-term stability" |
| Experience in Engineering Plastics and Specialty Materials | Primarily consisting of general-purpose plastics and a few engineering plastics | Familiar with various engineering plastics and their specific requirements |
| Mass Production Issue Resolution | Typically focused on debugging, with less emphasis on revisiting design decisions. | Comprehensive review of molds, materials, and manufacturing processes |
| Project Communication Methods | Primarily based on work orders and simple specifications | Conduct regular reporting and discussions using a project management approach. |
Customer Testimonials
Improving Yield Rates for High-Precision Mechanical Components
We developed a precision mechanical component with an initial yield rate of only about 60%. Severe dimensional deviations and warpage issues were present. Thanks to Chengxin for helping us re-evaluate the part design and material selection, ultimately improving the yield rate to over 90%.

Medical Equipment / Quality Engineer Chen
Engineering Plastic Material Selection and Cost Optimization
Originally, we used a single engineering plastic. Through practical analysis and mold comparison testing, Chengxin assisted in adjusting to a combination of two materials. This reduced the unit cost by over 20% and ensured stable mass production.

Chengxin Sealing King Service Process:
Provide 2D/3D drawings, functional requirements, and estimated quantities. Conduct preliminary discussions on project objectives, budget, and timeline.
Conduct manufacturability reviews for part structures, dimensional tolerances, and operating environments, and provide recommendations for material and design adjustments.
A comprehensive quotation will be provided based on mold complexity, material costs, and projected production volume. The project will commence upon mutual confirmation.
Create molds and conduct trial runs. Adjust parameters and make necessary modifications based on trial results until the desired quality is achieved. First, conduct small-scale trial production to verify assembly and actual usage conditions. After confirming no issues, proceed to stable mass production.
During mass production, we can continuously optimize to accommodate design changes, material adjustments, or capacity enhancement requirements.
For the highest-grade PI, look no further than Chengxin Sealing King!
If your product involves developing high-precision plastic components, or if you're stuck in the dilemma of "molds already made but unstable mass production," feel free to submit your drawings and requirements to Chengxin's professional PI team. Let our expert precision injection molding capabilities help you minimize risks before mass production begins.
Contact Chengxin Sealing King today to discuss your project background and timeline. We will provide preliminary feasibility recommendations and collaboration options to help transform your design into a stable, mass-producible product.
