Overview:
Our Custom EDM Medical Grade Tooling Mold for PVC Throat Tube Parts delivers precision-engineered mold solutions specifically designed for high-volume production of critical airway management components. These molds are manufactured using advanced EDM (Electrical Discharge Machining) technology combined with medical-grade stainless steels to achieve exceptional surface integrity, dimensional accuracy, and extended production life. Each mold is engineered to process USP Class VI compliant PVC materials, ensuring biocompatibility and consistent performance in emergency medical applications. With optimized cooling channels, wear-resistant components, and validated ejection systems, our molds guarantee efficient cycle times, minimal flash, and flawless part repeatability—enabling reliable manufacturing of translucent, kink-resistant throat tubes for intubation, suction, and surgical procedures.

High Cavitation Efficiency: Balanced multi-cavity layouts with conformal cooling achieve high yield and uniform shrinkage across all parts
-
Extended Tool Life: Corrosion-resistant steels and surface treatments withstand plasticizer exposure and repeated sterilization
-
Full Customization Support: Comprehensive DFM, mold-flow analysis, and validation sampling tailored to throat tube dimensions and connector features
-
Regulatory Ready: Full DMF (Device Master Record) and validation documentation support for FDA and CE submissions
Surface Treatment Options:
-
Mirror Polishing (Ra 0.02–0.04 μm): Ensures easy part release and optical clarity for tube inspection
-
Hard Chrome Plating & Nickel-PTFE Coating: Reduces adhesion and wear from flexible PVC compounds
-
Nitriding & PVD Coating: Increases surface hardness and resistance to abrasive plasticized materials

Passivation & Electropolishing: Prevents corrosion in high-humidity molding environments
Quality Assurance:
Each medical throat tube mold undergoes rigorous validation under our ISO 13485-certified quality system. Dimensional integrity is verified using ZEISS CMM and optical comparators, while surface quality is assessed with white light interferometry and digital microscopes. We conduct mold-flow analysis to optimize gate placement and cooling performance, and perform production trials using medical-grade PVC to validate part dimensions, tensile strength, and visual clarity. All molds are documented with complete inspection reports, material certifications, and production validation records.
Our Factory:
Our medical mold manufacturing facility is equipped with state-of-the-art EDM systems including Sodick mirror EDM machines and Mitsubishi slow wire-cutting systems, supported by 5-axis CNC machining centers and high-speed milling equipment. Dedicated cleanroom assembly areas, temperature-controlled polishing stations, and ultrasonic cleaning systems ensure contaminant-free mold finishing. All manufacturing processes are digitally integrated through CAD/CAM/CAE systems, with real-time monitoring and full traceability from raw material to final tooling delivery. We offer end-to-end support—from design and prototyping to production sampling and packaging validations—enabling our customers to meet stringent medical device manufacturing requirements with confidence.
