Insert Injection Mould for Medical Accessory Equipment

Overview  

Prosperity Technology Development Co., Ltd. presents a precision-engineered Household insert Injection Mould designed for high-accuracy spare parts in medical accessory equipment. This Family mould features S136 steel cavity & core, LKM mould base, and Sub-gate cold runner. The tolerance of 0.005 mm guarantees repeatable dimensional stability day after day, month after month, year after year. By integrating a dedicated precision injection machine, we replace conventional moulding injection methods to achieve superior surface finish and form accuracy on every injection part produced.  

Key features:  

- Material: ABS+PC blend with tensile strength >50 MPa  

- Cavity & Core steel: S136, hardness 48–52 HRC  

- Mould base: LKM standard P20 equivalent  

- Cold runner: Sub-gate system for optimized flow balance  

- Tolerance: ±0.005 mm on all critical dimensions  

- Machine: 100 ton precision injection tools  

Key Specifications

Material & Precision  

– The S136 cavity & core deliver high corrosion resistance and wear life >500,000 cycles under moulding injection conditions.  

– ABS+PC parts exhibit UL94 V-0 flame rating, making each injection part compliant with ISO 10993 biocompatibility standards.  

– Dimensional limit: ±0.005 mm ensures accurate fit on infusion, blood pressure, sputum suction, and fluoroscopy equipment accessories.  

– Household insert Injection Mould rigidity maintains positional accuracy between templates within 0.01 mm even after 100,000 cycles.  

Production Process  

a. Design & Simulation  

   • 3D flow analysis for balanced moulding injection flow  

   • Gate location optimized for weld-line elimination on each injection part  

b. Fabrication  

   • EDM sinker and wire-cut on S136 core & cavity  

   • Polishing to Ra 0.4 μm for critical surfaces  

c. Assembly & Trials  

   • Installed on precision injection tools press (100 ton)  

   • Trial runs measuring cycle time, part weight, and cavity balance  

d. Quality Control  

   • Coordinate measuring machine (CMM) gauge study on all injection parts  

   • Statistical process control (SPC) with Cp > 1.33 on key dimensions

Selection Guide  

To select the optimal moulding injection solution:  

1. Define part geometry, minimum wall thickness, and material (ABS+PC or equivalent).  

2. Confirm tolerance needs (down to ±0.005 mm for high-precision injection part).  

3. Specify cycle-time requirements (12–15 s on precision injection tools).  

4. Review previous case studies (e.g., hospital infusion accessories).  

5. Approve Family mould concept for multiple cavity efficiency.
