CSMFG supports custom injection molding from mold design and flow analysis to tooling, production, inspection, and assembly. The service is useful for buyers with complex plastic parts that need design support before mass production.
Let our custom injection molding engineers help you design the injection molded parts you need. We specialize in tough custom molding jobs where the design, choice of plastic, mold building and flow analysis are critical to production.
We are checking:
Fill time
Air traps
Confidence of fill
Flow front temperature
Injection pressure
Pressure drop
Quality prediction
Solid model
Weld lines

How we work on your mold design project
1
You send us your requirements
This can be drawings, samples, pictures, description, quantity, quality concerns… everything to make clear what you want.
2
We understand your needs
With our technical team we make perfectly clear what you are asking for - included processing and mold suggestion.
3
Mold design
We prepare all mold drawings and design. After completed, we will send it to you for approval before cutting steel
.
4
Mold making
This is a high precision process and includes CNC milling of mold core cavity need 10 – 40days.
5
Test molding
Quality check and tweaking for ,old and products. Takes usually 1 to 3 days.
6
Sample confirmation
We airship some samples to you. If not ok. We go back to step 5 until your satisfaction.
7
Mass production
Consistent quality is maintained by regular checking of products and mold condition.
8
Export logistics
We handle export logistics and ship to your door - doesn’t matter where you are.

Our Work
How we check your mold design
We pride ourselves for bringing our customers experience, China know-how, and world-class manufacturing quality. We are customer-centric, very process driven, and enthusiastic about China Manufacturing. Furthermore, we use many standard operating protocols (SOP) throughout the business process and state-of-the-art checking instruments. Already at the beginning of your new project, our engineers and quality experts are involved to check the critical points or to suggest improvements.
We are ISO 9001 certified and a corporate member of the American Chamber of Commerce in Shanghai.
Our state of the art QC-equipment
Distinct benefits of working with us:
Clear engineering communication in English and German, which is vital prerequisite for manufacturing projects
CSMFG supports custom injection molding from mold design and flow analysis to tooling, production, inspection, and assembly. The service is useful for buyers with complex plastic parts that need design support before mass production.
Process Overview
Part design review
Material and mold-flow check
Tooling design
T1 samples and corrections
Production molding and QC
Proof Point
The page lists checks for fill time, air traps, injection pressure, weld lines, flow front temperature, and quality prediction.
Manufacturing Specs for RFQ Review
For faster sourcing decisions, include the commercial context as well as the drawing package: target unit cost, expected order frequency, approval steps, packaging needs, destination market, and any standards the part must satisfy. This helps CSMFG compare tooling cost, process risk, inspection level, and production routing before quoting.
Buyers should also identify the part's end use, failure risks, cosmetic surfaces, and any regulatory or customer-specific requirements. Those details help align sampling, inspection reports, packing methods, and long-term production controls.
Materials
Engineering plastics and commodity resins selected by strength, temperature, appearance, chemical exposure, and production requirements.
Tolerances
Molding tolerances depend on resin, shrinkage, tool design, wall thickness, ribs, bosses, inserts, and post-mold assembly requirements.
Batch sizes
Prototype tooling, pilot production, and production tooling can be reviewed based on volume, expected tool life, and part risk.
Lead times
Lead time depends on mold complexity, steel selection, flow analysis, sample revisions, resin sourcing, and finishing.
QC checks
Mold-flow checks, fill confidence review, air trap analysis, sample inspection, dimensional checks, and production quality control.
RFQ requirements
Send 3D CAD, 2D drawings, resin preference, color, finish, annual volume, critical tolerances, inserts, and assembly needs.
