STAVAX Micro Core Pins for Thin-Wall Medical Injection Molds
Product Overview
STAVAX Micro Core Pins are ultra-precision mold components designed for thin-wall medical injection molding applications that require extremely small core diameters and high dimensional stability. These pins are primarily used to form micro holes, narrow channels, and fine internal structures in medical plastic components.
Manufactured from STAVAX ESR stainless mold steel, these micro core pins provide excellent corrosion resistance, superior polishability, and stable mechanical properties during high-cycle injection molding production. Their ultra-fine geometry enables molds to produce micro-scale plastic features with consistent accuracy and surface quality.
STAVAX micro core pins are widely used in thin-wall medical consumable molds, laboratory plastic molds, and high-precision micro injection molding tools.
Product Description
Thin-wall medical plastic products often contain extremely small holes or narrow internal channels. To form these features, molds require micro core pins with very small diameters and excellent straightness.
Because these pins operate under high injection pressure and repeated thermal cycles, both material quality and machining precision are critical.
STAVAX ESR stainless mold steel is widely used in medical mold tooling due to its:
- Excellent corrosion resistance
- Superior polishability
- High dimensional stability
- Good wear resistance for long production cycles
Our STAVAX micro core pins are produced using advanced precision turning, micro grinding, and fine polishing processes to achieve ultra-small diameters while maintaining structural strength and stability.
Key product features include:
- Manufactured from STAVAX ESR stainless mold steel
- Designed for micro feature formation in thin-wall molds
- Excellent corrosion resistance for medical environments
- Ultra-smooth surface finish for high-quality molding
- High straightness and dimensional stability
- Suitable for micro injection molding and high-cavity molds
- Custom diameters, lengths, and head structures available
- Machining tolerance up to ± 0.005 mm
These features ensure reliable performance in precision medical injection mold systems operating at high production volumes.
