Product Overview:

When a conventional thimble is injected into a mirror PC, medical catheter, or metal powder injection molding (MIM) when scratches are left on the parts, the air top becomes a hard need for high demoulding requirements. Our Titanium Nitride Coated Gas Ceiling Sleeves achieve contactless ejection with ≤ 0.003mm extreme concentricity and a self-lubricating microporous structure. It is applicable to medical parts and automotive optical parts with the accuracy of 0.01 mm, and the product yield is improved to 99.9%.
Product Features:

1. Military-grade precision, never deformed
- Two-stage hardening process: SKD 11 Substrate quenching (HRC62°) → cryogenic treatment → PVD coating (2000HV hardness)
- μ Level concentricity control: full CNC grinding, inside/outside tolerance ± 0.003mm, straightness ≤ 0.005mm/m
A thermal expansion resistance structure: a segmented thermal expansion tank, no clamping stagnation under 350° C working condition
2. Out-of-the-box standardization
- Global mold base compatibility: supports the DME family 1/2、HASCO Z Series, FUTABA E type standard size
- Elastic pre-tensioning system: Built-in wave spring, automatic compensation of die thermal deformation clearance
- Lubrication-free design: grapheme coating is self-lubricating for life, and oil pollution is eliminated
Product Application Scenario: 

1. Optical parts: lamp lens, mobile phone light guide plate without trace ejection
2. Medical parts: zero-pollution demoulding of catheter connector and transparent infusion set
3. Precision electronics: connector insert and micro gear are ejected without damage
4. Surface Finishes: IMD/IML anti-scratch of diaphragm and electroplated parts
