Expert in plastics injection molding, in our workshop in China we produce all types of plastic technical and appearance parts from small runs to mass production. We have fully automated injection presses from 70 to 1200T. The injected parts can then be assembled on our assembly lines and finalized by various finishing and decoration operations (metalizing, painting, inserts, etc.).
We work with all types of thermoplastic and elastomer materials according to customer specifications: ABS, PC, PMMA, TPE, PA, TPU, POM etc., with or without loading. We master different injection processes depending on the characteristics of the parts to inject. Our design office, a department central to our organization, ensures the optimization of the part whether it is at the prototyping or the molding by injection stage. In addition, it takes charge of the design of the plastic injection molds and the 3D drawings will be given to you. The molds will be manufactured in our tooling workshop and maintained in our dedicated and laid-out storage room.

PLASTIC INJECTION MOLDING WORKSHOP
Our injection molding workshop is equipped with an automated fleet of thermoplastic injection presses from 70 to 1200T. We produce series from several thousand to several million pieces. Our team is comprised of expert plastics engineering technicians in particular with several installer-adjusters and machine operators. All our presses are robotized with gripping hands and independent peripherals (cooling unit, temperature controller, etc.) for continuous 24/7 production. The material unit directly supplies the presses and each one has a colorimeter to ensure constant coloring for all productions.
We follow a production and quality control register in order to have proper control and monitoring of faults on injected parts. For the plastic raw material, we have established rigorous traceability on the sourcing and use of it during the production (management of discards, re-grinding, etc.). We have an inspection center equipped with conventional tools (gages, Vernier calipers, etc.) and are able to install specific inspection tools like dimensional templates.
INJECTION
Entirely automated Injection machine fleet, materials unit and independent peripherals, colorimeter. Large choice of thermoplastic materials.
INSPECTION
The inspection of injected parts and the establishment of quality control documentation (PPAP, CP/CPK, dimensional report)
TRACEABILITY
We supply material certificates as guarantee on the materials used. Internal storage and maintenance of the molds.
MATERIAL SELECTION
Plastic material: Some factors need to be consider.
1.) Transparent: GPPS, PC, Acrylic
2.) Corrosive material: PVC.
3.) Abrasive resistance material: PA, PC, POM, glass fiber filled.

Plastic Injection Molding Cost Analysis
The cost calculation is based on my own experience in Shenzhen, China:
Injection molded parts cost = plastic material cost + processing cost + packing cost + shipping cost
Material cost = [(1 + plastic material loss) * product weight * Batch + debug material lost weight + normal rejection rate * product weight * Batch] * Material Unit Price / Batch.
Where the plastic material loss is 3% -5% generally; general products of debug material lost weight and normal rejection weight is 5000g - 15000g.
Processing cost = (debug time / batch + molding time / mold cavities) * plastic injection molding machine processing costs
| Injection Molding Machine (T) | Cost (Yuan/hour) | Injection Molding Machine (T) | Cost (Yuan/hour) |
| 80 | 35 - 45 | 200 | 110 - 160 |
| 100 | 45 - 60 | 250 | 150 - 200 |
| 120 | 65 - 85 | 300 | 180 - 220 |
| 150 | 80 - 110 | 350 | 200 - 250 |
| 180 | 95 - 140 | 400 | 250 - 350 |
OUR ASSISTANCE WITH PLASTIC INJECTION MOLDING
Plastic injection molding is a specific manufacturing process and we assist you right from the start for the success of your project. The analysis of moldability (and rheology) of your 3D concept by our design office, is an important step. In fact, it allows possible problems to be identified and eliminated (injection point, ejection, voids, counter-clearances, wall thicknesses, etc.) on your parts. The design of the tooling comes directly from it and in particular, 4 characteristics are to be anticipated: the point of injection, the layout of the ejectors, the sealing plane line and the clearances.
We also guide you on the choice of materials. We have access to a hundred thermoplastics according to your needs. The choice of it will be defined depending on your specifications, mechanical properties, its environment and the necessary certifications. Closest to your many needs, we master the main processes of plastic injection molding: single-material molding, dual-material molding, gas assisted injection, insert over-molding. For small runs in the proper material, we offer injection with a mold prototype.
DECORATION AND FINISHING OPERATIONS ON PLASTIC PARTS
Secondary Process
We perform most of the finishing operations (graining, plastic chrome-plating, painting, plastic metalizing, marking, etc.) of your injected plastic parts and sub-assemblies. We have the necessary in-house organization and equipment and for certain needs.
After the injection of your raw parts, we provide all of the desired finishing, as per your specifications, in order to deliver you a “finalized” part with the proper surface state. It is also possible for us to add elements and components to the injected part (see assembly and sourcing section). This post-injection step in fact, allows the part to be “finished” and the final desired appearance to be produced.
Our in-house machining center performs all the required rework of certain dimensions, performs tapping, cutting, etc.
These added-value plastic part decoration operations are interesting to have done directly in China for cost and time savings.
FINILIZING
Rework operations (drilling, milling, etc.)
Addition of elements or inserts
Stamping: marking and logo
Screen printing
Laser, color marking
FINISH
Industrial polishing
Glossy polishing
Mirror polishing
Sanding
Texture – charmille
