HLH Prototypes has experience working with clients throughout the injection molding process, from tooling and initial samples to production and final delivery. You can get the parts you need at a reasonable price while still keeping an eye on quality and turnaround time.
How much does injection molding cost in China?
The final price of your China injection molding service will depend on different factors.
Cost factor — What to expect
Mold cost: $2,000 to $15,000, depending on your project’s complexity and material of choice (steel or aluminum).
Per-unit cost: $0.10 to $2.00 per item for large production runs.
Material selection: Special materials like PEEK could cost you 15 to 80 times more than standard plastics such as ABS.
Labor and setup: Lower labor costs can help reduce your setup expenses compared ...
... with many Western markets.
Production volume: You could reduce per-unit costs for larger runs, with potential savings of around 30% to 50%.
 
Although you need a larger upfront investment for tooling, you could spread that cost across your whole order by producing more parts.
How fast can you get your parts from China?
Lead times depend heavily on mold complexity and revisions.
Stage factor — Typical timeline / impact
Tooling and mold design: Around 3 to 5 weeks
Sample production and approval: Around 1 to 2 weeks for samples and T1/T2 revisions
Mass production: Around 1 to 3 weeks after mold approval
Note that incomplete drawings can cause delays because the manufacturer will need to request clarification. Design changes may also require additional revisions and testing.
If you want to avoid unnecessary delays, it helps to have clear technical drawings and good communication with your China injection molding partner.
“Our goal has always been to give customers access to world-class manufacturing through one trusted, quick-turn partner. We can deliver prototypes in days and injection-molded parts in as little as two weeks,” says James Murphy, co-founder & director of HLH Prototypes.
How does quality control work in China?
When choosing a reliable China injection molding manufacturer, make sure they take the time to inspect your materials and finished parts throughout production.
Quality control method — What it checks
Material verification: Resin specifications and consistency
CMM inspect  ion: Dimensions and specified tolerances
First Article Inspection (FAI): Initial parts before mass production
Batch testing: Strength, durability, consistency, and visible defects
An injection molding partner won’t also hesitate to share clear inspection reports and certifications to give you more confidence in their services. When comparing manufacturers, see if they have verified and active certifications like IATF 16949 and ISO 9001.
