Zorapid Systematic Mold Production Process
Beyond mold making, we create reliable production solutions through our refined four-stage process.
DFM Analysis & Engineering
Zorapid Rapid offers free professional DFM analysis before mold production starts. We optimize wall thickness, draft angles, and gating systems to avoid defects such as sink marks and warping, making your design fully ready for stable, high-efficiency mass production.
Precision CNC & EDM Machining
We perform high-precision CNC machining for mold cores and cavities. For complex, fine details that regular milling cannot achieve, Zorapid Rapid uses EDM to deliver sharp contours and intricate surface textures with precision up to ±0.0254mm.
Multi-Slide & Specialized Tooling
For parts with undercuts and complex side features, we build custom multi-slide molds. This advanced tooling enables automatic ejection, shortens cycle times, and eliminates costly secondary machining.
Mold Trial & Validation
Every mold goes through strict T1 first trial at Zorapid Rapid. We provide molded samples and complete dimensional inspection reports to ensure full consistency with your 3D CAD data before mass production.

Our Common Materials for Injection Molds
Material choice defines mold quality, service life, and final product performance. At Zorapid Rapid, we engineer with purpose-selected steels to ensure superior precision, efficiency, durability, and aesthetic results.
Pre-Hardened Plastic Mold Steels
Pre-hardened to 28–40 HRC, these steels allow direct machining without extra heat treatment. Featuring low deformation and excellent stability, they are the ideal choice for most standard and precision molds.
Below are our most popular grades:
Age-Hardening Stainless Steels
These steels gain exceptional hardness through precise heat treatment (solution + aging for age-hardening grades, quench + temper for 420).They offer outstanding corrosion resistance and superior mirror polishing, ideal for transparent, medical, optical, and high-gloss applications
Aluminum Alloys
Aluminum 7075 alloy is ideal for rapid prototyping and efficient manufacturing.Excellent thermal conductivity and machinability shorten lead times and cooling cycles.Strong heat dissipation ensures higher productivity and reliable performance in precision molding applications.

FAQ
1.What is the typical lead time for a custom injection mold?
At Zorapid, we make mold lead times transparent and predictable, structuring timelines around your project’s unique needs to avoid delays and ensure quality:
Rapid Prototyping & Simple Molds (1–3 Weeks): Streamlined production for single-cavity, low-complexity molds.
Delivers production-ready parts quickly for validation or short-run production, no unnecessary wait times.
Production Molds (3–5 Weeks): Standard multi-cavity molds with mechanical features (sliders, lifters).
Designed for consistent, high-volume output—ideal for consumer and industrial products demanding reliability and speed.
High-Complexity & Precision Molds (5–10+ Weeks): For engineered-to-order molds (2K, unscrewing, medical-grade). Extra time allocated for precision heat treatment, intricate EDM work, and exhaustive T1 testing to meet strictest industry standards.
2.How does Zorapid guarantee mold quality and long-term support?
Quality Assurance Through Precision Engineering
Global Support Matches Your Pace
- Global on-site engineering support
- 24/7 remote video troubleshooting
- Digital mold archives for fast CNC spare parts
- Full mold warranty with guaranteed cycle time & tool life
3.How do you eliminate vacuum voids and internal stress in thick‑walled transparent parts?
For high‑transparency components like optical lenses and luxury packaging, uneven cooling often causes vacuum voids, shrinkage, and internal stress.
Zorapid solves this with 3D‑printed conformal cooling combined with high‑thermal‑conductivity beryllium copper inserts.
Cooling channels precisely follow the part contour to ensure uniform heat dissipation. This effectively eliminates vacuum shrinkage and internal stress, delivering flawless optical clarity.
4.How do you safeguard my IP and confidential design information?
We understand that IP protection is critical for global customers. Zorapid operates a professional confidentiality system to protect your proprietary technology and designs.
Encrypted Data Management Your drawings and 3D files are saved in encrypted storage with limited access only to authorized engineers.Confidentiality Commitment We sign binding NDAs and can use project codes instead of real part names to maintain internal confidentiality. Safe Destruction All leftover materials, test samples and rejected parts are safely disposed of to eliminate leakage risks.
