medical injection moulding

In addition, our company has established cooperative relationships with plastic raw material suppliers, printing manufacturers, etc. to ensure the supply of raw materials and printing quality. Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized medical injection moulding products to meet their specific needs. At the same time, we have 10 years of professional foreign trade service experience, understand the foreign trade process, and better serve our customers. For medical injection moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

Medical injection molding needs to meet the requirements of zero defects, biocompatibility, and traceability. The following are systematic technical points and innovative practices

1. Material science breakthroughs (clinical-grade polymers in 2025)

1. High-end material selection matrix

Medical-grade PEEK, orthopedic implants, nano-hydroxyapatite enhancement (bone fusion rate ↑40%)

Gamma-irradiation-resistant COP, prefilled syringes, transparency retention rate after irradiation > 98%

Antibacterial TPE, respiratory mask, silver-loaded zeolite long-term antibacterial (> 99.99% efficiency)

Degradable PLGA, drug sustained-release microsphere carrier, degradation rate AI controllable (error ± 3 days)

2. Ultra-clean environment control (Class 5 clean room standard +)

1. Double revolution of particle control

graph LR

A [environment] --> B (0.3μm particles <100/m³)

C [equipment] --> D (in-mold cleanliness ISO 3 level)

Innovative solutions:

Electrostatic adsorption wind wall (particle sedimentation rate ↓90%)

Mold nitrogen positive pressure protection (oxygen content <50ppm)

2. Dynamic monitoring of microorganisms

Online ATP bioluminescence detection (automatic sampling every 2 hours)

Disinfection upgrade: hydrogen peroxide plasma sterilization (instead of ethanol wiping)

III. Precision mold technology (micron-level precision guarantee)

1. Core design standards

Parting surface flatness, ≤0.005mm, ≤0.02mm

Conformal cooling water channel accuracy, ±0.01mm, ±0.05mm

Demolding slope compensation algorithm, AI real-time deformation correction, fixed compensation value

2. 2025 innovative process

Micro injection molding: embedded production in a Class 100 clean room (minimum part 0.1mg)

Laminar mold technology: production capacity increased by 80% (insulin syringe 24-cavity mold)

IV. Key points of process control (zero-defect production core)

1. Closed-loop control of key parameters

Melt temperature, ±0.5℃, infrared thermal imaging online feedback

Packaging pressure, ±0.2%, cavity pressure sensor array

Cooling uniformity, ΔT≤1.5℃, mold embedded thermocouple

2. Defect prevention technology

Black spot control: supercritical CO₂ barrel cleaning (once per shift)

Internal stress elimination: multi-stage annealing process (temperature control accuracy ±0.3℃)

V. Quality and compliance system (full life cycle traceability)

1. Smart detection system

graph TB

A[First article inspection] --> B(AI visual 100% size comparison)

C[Process sampling] --> D(Micro CT porosity analysis)

E[Finished product test] --> F(Cytotoxicity automatic incubator)

2. Blockchain traceability

Material batch → process parameters → sterilization records are fully chained (compliant with FDA UDI 2.0)

Real-time warning: Deviation data triggers the smart contract to automatically stop production

VI. Green smart manufacturing practice

Energy use, electromagnetic induction heating, energy consumption ↓45%

Waste, supercritical water oxidation recovery, carbon footprint ↓70%

Clean room, ion membrane dehumidification and recycling system, water and electricity consumption ↓60%

VII. Risk control list

Silicone oil migration, ≤0.6μg/cm² (ISO 10993-18), plasma spraying fluorinated release layer

Extractables, USP<665> new standard, accelerated solvent extraction pre-inspection

Data integrity, 21 CFR Part 11 electronic signature, quantum encryption process database
