Product Advantages
High-Efficiency 8-Cavity Tooling Structure
Symmetrical 8-cavity layout paired with precision guide pillars ensures uniform melt filling and balanced cavity pressure across all positions, shortening cycle times and slashing unit costs for bulk production.
Multi-Directional Mechanical Slide Mechanisms
Heavy-duty external slide blocks enable smooth actuation for undercuts, side textures, and internal retention clips without dragging marks, whitening, or structural distortion.
Optical-Grade Mirror Polish (Invisible Gate Marks)
Finished to SPI A1 diamond polish standards, yielding crystal-clear or high-gloss surfaces straight out of the tool. Hidden gating technology ensures flawless substrate readiness for vacuum metallization and painting.
Precision Assembly Tolerances & Leak-Proof Sealing
Machined within ±0.005mm precision to ensure smooth screw-thread engagement, crisp snap-in tactile feedback, and flawless hermetic sealing that easily passes negative-pressure vacuum leak tests.
Turnkey Full-Lifecycle Manufacturing
Integrating UG 3D CAD design, Moldflow analysis, high-speed CNC, wire EDM, T1 validation, automated molding, and secondary finishing for end-to-end quality control and rapid turnaround.

Frequently Asked Questions
1
Q: What is the typical tooling lead time, and how long does it take to provide T0 samples?
A: Upon final approval of the 3D part design and DFM report, tooling fabrication typically takes 25–35 business days. T0 mold trials are scheduled immediately after tool assembly, and initial sample parts (with FAI dimensional and material reports) are dispatched via air courier within 48 hours for client approval.
2
Q: How does the mold prevent sink marks, bubbles, and flow lines on heavy-walled or high-gloss caps?
A: We utilize advanced Moldflow analysis to optimize gate locations, integrate precision parting-line micro-venting, and design high-density conformal water circuits. Coupled with multi-stage holding pressure profiles and accurate mold temperature control, thick-walled parts are produced free of sink marks, voids, and knit lines.
3
Q: Besides mold building, do you offer in-house injection molding, metallization, and assembly services?
A: Yes. We operate an integrated facility housing mold making, clean-room injection molding, vacuum metallization, UV coating, silk-screening/hot-stamping, and sub-assembly. Clients can choose between purchasing the exported molds or retaining the tooling at our factory for turnkey contract manufacturing (OEM/ODM).
