Product Overview
This is a ISO13485 certified medical-grade injection mold specially developed for producing transparent luminous button shroud parts used in medical equipment. Adopting premium 738H mold steel with HRC35-40 hardness and professional 1+1+1 submarine gate large sprue runner system, the mold perfectly adapts to high-transparency, high-purity medical grade PC material. It ensures flawless transparent appearance, stable luminous effect, zero impurities and high dimensional consistency for medical button shrouds. Manufactured under strict ISO13485 medical quality management system, this mold fully meets medical device production standards with complete process traceability, clean production requirements and validated molding procedures, ideal for mass production of medical luminous button protective covers and precision medical plastic housings.
Core Mold Structural Advantages
1. Unique 1+1+1 Submarine Gate + Large Sprue Design
Equipped with customized 1+1+1 three-group balanced submarine gate structure and enlarged large sprue channel, this medical mold solves the filling difficulty of high-viscosity medical PC material effectively. The balanced gating system realizes synchronous and uniform plastic filling, effectively eliminating weld lines, air bubbles, shrinkage marks and flow marks on transparent PC button surfaces. The hidden submarine gate ensures automatic gate breaking and clean product surface without manual trimming, greatly improving yield and production efficiency. Large sprue design stabilizes injection pressure, avoids material shortage and ensures ultra-clear transparent appearance and stable luminous transmission performance of button shroud.
2. 738H Steel HRC35-40 Stable Hardness for Medical Molding
The core and cavity adopt original 738H pre-hardened mold steel with precise hardness controlled at HRC 35-40. This steel grade features excellent surface polishing performance, uniform hardness, low deformation rate and superior corrosion resistance, perfectly suitable for long-term continuous production of high-transparency medical PC parts. It supports ultra-high mirror polishing to achieve Ra≤0.2μm smooth cavity surface, effectively preventing dust adhesion, material residue and microbial growth, which fully complies with medical-grade clean production standards. Stable mechanical properties ensure long-term dimensional accuracy without deformation, with mold service life up to 600,000+ shots.
3. ISO13485 Medical Standard Compliance & Full Validation
The entire mold design, processing and trial production are implemented under ISO13485 medical device quality management system. We provide complete quality documents including material certificates, heat treatment reports, dimensional inspection reports and mold validation records (IQ/OQ/PQ). The mold structure is optimized with no dead corners, no residual gaps, easy cleaning and disinfection, effectively avoiding bacterial breeding and particle contamination. All production processes are traceable, meeting strict medical industry regulatory requirements and supporting customers’ medical device registration and quality audit.
4. Professional Optimization for Transparent Luminous PC Parts
Aiming at the luminous light transmission demand of medical button shroud, we optimize mold cooling system and exhaust structure. Uniform circulating cooling channels ensure rapid and balanced cooling, preventing internal stress and transparent part cracking. High-precision exhaust slots eliminate trapped air, guaranteeing ultra-clear transparent body and uniform luminous effect after light transmission. The finished PC button shroud features high light transmittance, no haze, stable luminous performance and smooth edge appearance, fully meeting the aesthetic and functional requirements of high-end medical equipment.

FAQ
1. Why choose 738H HRC35-40 steel for medical transparent PC molds?
738H steel with HRC35-40 hardness has uniform internal structure, excellent mirror polishing performance and low stress, which can perfectly avoid surface defects of transparent PC parts. It features good corrosion resistance and wear resistance, suitable for long-term medical-grade clean production, and effectively ensures stable luminous and light-transmitting effect of button shrouds.
2. What is the advantage of 1+1+1 submarine gate large sprue structure?
The 1+1+1 balanced gating system realizes uniform filling of high-purity medical PC material, no weld lines or bubbles on transparent surfaces. Large sprue improves fluidity, reduces injection pressure and protects mold precision. Submarine gate realizes automatic cutting, no secondary processing, meeting medical high-cleanliness requirements.
3. Can you provide ISO13485 related certification documents?
Yes. We can provide complete ISO13485 certification, steel material certificates, heat treatment reports, mold inspection reports and process validation documents to support your medical product registration and quality system audit.
4. Is this mold suitable for glass-filled or food-grade medical PC?
This mold is specially optimized for high-transparent medical pure PC materials. It supports food-grade and medical-grade PC molding with stable performance and ultra-high finished product qualification rate.
