Core Product Advantages
1. Ultra-High Precision for Medical Matching Requirements
Medical connectors and adapters require extremely strict fitting accuracy. This mold adopts precision CNC machining and high-precision core cavity matching technology to control product tolerance within ±0.01mm. The molded Luer threads and connecting interfaces are smooth and accurate, ensuring tight locking, no loosening, no liquid leakage, and perfectly meeting clinical infusion and pipeline connection standards.
2. Medical Clean & Zero-Defect Molding Performance
Optimized exhaust and gating design effectively eliminates trapped air, flow lines and burrs. The mold surface adopts high-standard mirror polishing or fine texture treatment, making the product surface smooth and easy to clean. No residual corners or sharp edges avoid hidden dangers of bacterial growth, fully adapting to medical clean production and disinfection requirements.
3. Adaptable to Multiple Sterilization Methods
The mold structure and shrinkage rate are professionally optimized for medical special plastics. The finished parts can withstand repeated EtO sterilization, gamma ray sterilization and high-temperature disinfection without deformation, cracking or performance attenuation, maintaining stable physical properties and biocompatibility.
4. Mature Complex Structure Molding Technology
Aiming at the complex undercut, thread and multi-way structure of three-way stopcocks and special-shaped connectors, we adopt precise slider core-pulling and oblique top demolding mechanism. The mold runs stably with high demolding efficiency, no product deformation, and ensures consistent batch yield and excellent product uniformity.
5. Standardized Medical Mold Manufacturing Process
The whole mold production process is implemented in accordance with ISO13485 medical system standards, with strict raw material inspection, mold precision testing, mold trial verification and sample confirmation. Complete process documents and quality reports can be provided to support customers’ medical device certification and market registration.
