Custom Medical Interface Mold Parts & Precision PET Preform Components | Zero-Defect Tooling for Cleanroom Molding

Elevating Medical & Packaging Standards through Micron-Precision

Where Biological Safety Meets High-Speed Manufacturing Efficiency

In the sectors of Medical Devices and PET Preform packaging, the margin for error is zero. Senlan Precision manufactures High-Precision Interface Mold Parts and Multi-Cavity Preform Components that adhere to the strictest global standards.

Our mission is to help molders achieve ultra-fast cycle times while maintaining 100% part consistency, ensuring your production line exceeds ISO 13485 and food-grade compliance requirements.

Solving the Critical Challenges of Medical & Packaging Molders

1. Absolute Material Purity for Cleanroom Integrity

• The Issue: Trace impurities in mold steel can lead to micro-pitting and oxidation, contaminating sensitive medical interfaces.

• Our Solution: We exclusively use premium STAVAX ESR, M333, or Mirrax stainless steels. Combined with vacuum heat treatment, our components offer superior corrosion resistance, eliminating the need for anti-rust agents in cleanroom environments.

2. Sub-Micron Consistency for Multi-Cavity Synchronization

• The Issue: Dimensional variations across cavities cause uneven wall thickness in PET preforms and flash in medical connectors.

• Our Solution: Utilizing MAKINO high-speed machining and high-precision grinding, we maintain tolerances within ±0.002mm. This ensures 100% interchangeability across 96+ cavity systems, minimizing mold setup time and balancing melt flow perfectly.

3. High-Performance Surface Engineering for Rapid Ejection

• The Issue: Part sticking and gas trap buildup lead to aesthetic defects and increased cycle times.

• Our Solution: We provide SPI-A1 Mirror Polishing (Ra 0.02μm) and specialized DLC (Diamond-Like Carbon) coatings. These treatments reduce the friction coefficient and material buildup, allowing for "dry running" without lubrication and faster part release.

FAQ – Technical Solutions for High-Precision Tooling

Q: Can you guarantee 100% interchangeability for a 128-cavity preform mold?

A: Yes. By using dedicated fixtures and CNC-controlled grinding processes, we ensure that every core or cavity is a "clone" of the master design within ±0.002mm.

Q: How do you prevent "Rust Pitting" in STAVAX parts?

A: We use genuine ESR (Electro-Slag Refining) grades, which have extremely low impurity levels, followed by a specific vacuum quenching process to maximize chromium distribution for peak corrosion resistance.

Q: Do you support small-batch replacement orders for medical molds?

A: Absolutely. We understand the urgency of mold repair. We can produce high-precision replacement inserts from your original 3D data with rapid global shipping.
