Q1: What industries rely most on injection molding?
Injection molding is widely used in automotive, medical devices, consumer electronics, home appliances, and industrial equipment. For example, automotive parts like dashboards and clips, medical consumables like syringes and casings, and electronics housings are all produced by injection molding due to its high repeatability and cost efficiency.
Q2: How long does it take to build a custom injection mold?
The timeline depends on mold complexity, size, and finishing requirements.
Simple molds (1–2 cavities, common materials): about 2–3 weeks.
Medium complexity molds (multi-cavity, precision parts): about 4–5 weeks.
Complex molds (with sliders, hot runner, multi-material): about 6–8 weeks.
Our in-house machining capability allows us to shorten lead time while maintaining accuracy.
Q3: What are the cost advantages of working with a Chinese injection molding factory?
Chinese mold factories, like ours, can reduce costs by:
Lower tooling and labor costs (up to 30%–40% savings) compared to Europe/US.
Full in-house production (design, machining, molding, QC, shipping).
Mature supply chain for steel, hot runners, and surface treatments.
Despite the lower price, we follow international mold standards (HASCO, DME, MISUMI) to ensure compatibility and quality.
Q4: Do you provide low-volume as well as mass-production services?
Yes. We support:
Low-volume molding (100–1,000 pcs) for prototyping, market testing, or bridge production.
Mass production (10,000+ pcs) with multi-cavity molds for stable, cost-effective runs.
This flexibility allows startups and established brands alike to benefit from our services.
Q5: How do you ensure quality in molded parts?
We implement strict QC processes:
Mold trial & validation before shipment (T1, T2 sampling).
CMM inspection, hardness testing, and surface roughness checks.
Batch inspection during molding to ensure dimensional stability.
Final inspection reports & documentation provided with shipments.
This ensures every shipment meets customer specifications and global standards.
