YIXUN mold
8480419090
Our 1×1 double color injection mold is a high-precision manufacturing solution engineered specifically for producing plastic parts using PP (Polypropylene) and TPE (Thermoplastic Elastomer) materials. Designed with medical-grade precision and compliance in mind, this mold integrates advanced dual-shot molding technology to achieve seamless bonding of two distinct materials in a single production cycle. Ideal for medical devices, healthcare accessories, and precision plastic components, the mold delivers consistent part quality, exceptional dimensional accuracy, and efficient production performance—meeting the stringent requirements of medical industry standards and high-volume manufacturing.
Shape: It has a "T" form: the top is a flat mounting base, and the bottom is an ergonomic handle for comfortable holding.
Two-color design:
Black section: A rigid base material (usually PP/ABS hard plastic) that acts as the structural frame, providing mechanical strength.
Orange section: A soft overmolded layer (typically TPE/TPR thermoplastic elastomer) covering the handle area, which enhances grip comfort and anti-slip performance.
First, inject the black rigid substrate (e.g., PP) to form the "skeleton" of the part.
Then, inject the orange TPE soft material (via the same double-color mold or a secondary mold) to bond it to the substrate. This creates a "hard frame + soft touch" combination.
Material pair: Common is PP (rigid) + TPE (soft)—they bond firmly via physical anchoring and chemical affinity, avoiding delamination during use.
Screw holes/slots on the base: For attaching the handle to the main body of tools (e.g., cleaning tools, small equipment).
Groove textures on the handle: Boost friction for a stable grip, while adding visual appeal.
Opening at the bottom: Likely for hanging storage or as a functional interface.

Specifically engineered for medical-grade PP and TPE materials, which meet ISO 10993 (Biological Evaluation of Medical Devices) and USP Class VI standards.
TPE-PP bonding optimization: The mold’s dual-shot design ensures strong, durable adhesion between the rigid PP substrate and soft TPE overmold, eliminating delamination risks—critical for medical devices (e.g., handles, grips, seals).
Non-toxic, odorless, and sterilizable: The mold’s surface finish and material selection support ethylene oxide (EO) sterilization, gamma radiation sterilization, and autoclaving (depending on part design), complying with medical hygiene requirements.
High-precision machining: Cavity and core are manufactured using 5-axis CNC milling, EDM (Electrical Discharge Machining), and wire-cutting technology, ensuring dimensional accuracy of ±0.005mm—ideal for tight-tolerance medical components.
Advanced temperature control: Dual-zone temperature regulation for PP and TPE nozzles prevents material degradation, ensures uniform melting, and maintains consistent part quality across high-volume production runs.
Warpage reduction: Conformal cooling channels (matching the part’s geometry) provide rapid, uniform cooling, minimizing material shrinkage and warpage—critical for parts requiring tight fitment (e.g., medical device housings, connectors).
Premium mold materials: Cavity/core made of S136/H13 heat-treated steel (HRC 52-56) offers excellent wear resistance, corrosion resistance, and impact resistance—suitable for high-cycle production (≥1 million shots).
Anti-rust treatment: Mold base and moving parts are coated with chrome plating or nitride treatment, enhancing corrosion resistance and extending service life in harsh production environments.
Maintenance-friendly design: Modular structure with standardized components (e.g., guide pins, bushings, ejector pins) simplifies maintenance, reduces downtime, and lowers long-term operational costs.
1×1 dual-shot design: Integrates two molding steps into one cycle, eliminating the need for secondary assembly or bonding—reducing production time by 30-50% compared to traditional single-color molding.
Short cycle time: Optimized cooling system and precise process control shorten cycle time to 15-30 seconds, maximizing production output for high-volume orders.
Material waste reduction: Precision injection control and minimal runner design reduce material waste to ≤3%, lowering raw material costs (critical for expensive medical-grade materials).
Flexible design adaptation: Supports custom cavity shapes, surface textures (e.g., matte, anti-slip), and TPE overmold positions to meet specific product requirements (e.g., ergonomic medical device grips, color-coded components).
Mold modification support: Our engineering team provides post-delivery mold modification services to adapt to design changes or production process optimizations.
Medical device components: Handles for surgical instruments, grips for diagnostic equipment, soft-touch overmolds for infusion pumps, and seals for medical containers.
Healthcare accessories: Toothbrush handles with soft TPE grips, infant feeding bottle nipples (TPE) with PP bases, and ergonomic handles for rehabilitation equipment.
Precision medical parts: Catheter connectors, drug delivery device components, and medical-grade plastic closures with TPE gaskets.
Mold manufacturing certification: ISO 9001:2015 (Quality Management System) and ISO 13485:2016 (Medical Device Quality Management System) – Ensures compliance with medical industry standards.
Material certification: Provide material test reports (MTR) for mold steel and compatible PP/TPE materials, including biocompatibility test results (ISO 10993) and USP Class VI certification.
Strict quality inspection: Each mold undergoes dimensional inspection (CMM), pressure testing, and trial production (≥500 shots) to ensure no leakage, stable ejection, and consistent part quality.
Technical Consultation: Professional engineers provide one-on-one support for mold design, material selection, and process optimization, ensuring the mold meets your product’s functional and compliance requirements.
Custom Design & Development: Accept 3D model (STEP/IGES/STL) input, offer DFM (Design for Manufacturing) analysis, and optimize mold design to improve production efficiency and part quality.
Trial Production & Validation: Provide trial production services, test part samples, and adjust the mold based on sample feedback until meeting your quality standards.
Delivery & Installation: Offer fast delivery (25-45 working days for standard molds), and send technical personnel for on-site mold installation, debugging, and operator training if required.
After-Sales Support: 12-month warranty period, 24/7 technical support, and prompt supply of spare parts (e.g., ejector pins, nozzles) to minimize production downtime.
Medical Industry Expertise: Focus on medical-grade injection molds for 15+ years, with deep understanding of medical material properties, compliance requirements, and precision manufacturing standards.
Advanced Manufacturing Equipment: Equipped with 5-axis CNC milling machines, EDM machines, CMM inspectors, and double color injection molding machines for mold production and testing.
