Product Overview
This is a high-precision 1×2 cavity injection mold purpose-built for manufacturing the Gaika Cangovaya snap-fit housing (3-4-5P, 32A), a mineral-filled polypropylene structural component. Engineered for medium-to-high volume production, this mold combines robust hot-runner side gating technology, premium 1.2344 tool steel, and tight process control to deliver consistent, dimensionally accurate parts with zero assembly or cosmetic defects.
Key Mold & Product Features
✅ 1×2 Cavity Balanced Production
Two parts per cycle balance output efficiency with cost control, making it ideal for mid-volume industrial and consumer applications.
✅ PP-MD40 Material Compatibility
Optimized for 40% mineral-filled polypropylene, the mold accommodates the material’s low shrinkage rate (1.1%) to ensure precise snap-fit tolerance and dimensional stability.
✅ Hot Nozzle Side Gating System
Eliminates cold runner waste, shortens cycle times, and leaves minimal gate marks on the product surface, preserving the housing’s smooth exterior finish.
✅ Premium 1.2344 Tool Steel Construction
Both core and cavity are crafted from 1.2344 (H13 grade) tool steel, heat-treated to HRC 48–52 for exceptional wear resistance, thermal fatigue performance, and long mold life (≥500,000 cycles).
✅ Precision Snap-Fit Geometry
Engineered with dedicated lifters/side actions to form the 3-4-5P internal undercuts, ensuring reliable snap-fit assembly for end-use applications.
✅ Low Shrinkage Compensation
Designed with a 1.011 shrinkage factor to counteract the material’s inherent properties, guaranteeing consistent part dimensions across every production run.

FAQ
Q: Is this mold suitable for high-volume production?
A: Yes. The 1×2 cavity design, paired with durable 1.2344 tool steel and a hot-runner system, supports consistent high-volume production with minimal downtime.
Q: Can the mold be adjusted for different shrinkage rates?
A: Yes. The mold is designed with modular components that allow for shrinkage compensation adjustments, and can be modified for other filled or unfilled PP grades.
Q: What is the typical lead time for mold delivery?
A: Standard lead time ranges from 6–8 weeks, including design review, mold flow analysis, trial runs, and first article inspection (FAI).
Q: Does the mold include undercut lifters for the snap-fit features?
A: Yes. The mold is equipped with precision lifter mechanisms to form the 3-4-5P internal undercuts, ensuring clean ejection without part damage.
Q: Can the mold be adapted for different housing sizes?
A: Yes. The core and cavity inserts can be customized to accommodate variations in diameter, length, or undercut configuration to match your product specifications.
