Guide to Design for OEM Injection Machining

TEAM MFG’s main business is CNC Machining, plastic injection molding, and stamping parts.

TEAM MFG can influence all types of project decisions, including but not limited to:
•    Type and form of raw material used
•    Dimensional tolerances
•    Wall thickness and draft
•    Secondary processing, such as finishing
•    Overall method of manufacturing the product

We now have sophisticated CNC machining center, engraving and drilling machine, lathe and milling machine, line cutting and other equipment.

With these machines and experienced employees, we are able to make repeated positioning accuracy within tolerance 0.005mm, providing strong guarantee for precision parts. We strive to exceed our customers' expectation in all aspects of product manufacturing process, and recognize our great responsibilities to our customers, employees, suppliers and society. We keep adopting advanced production facilities to improve efficiency and ensure high and stable quality, and further reduce the production cost.

The objective is to create reliable, viable and affordable molds, CNC machining parts and fast sample service for every industry. Through years' experience and development, TEAM MFG has become one of the biggest CNC machining industry, and build an impressive reputation from our partners and customers. Based on our accurate machining, competitive cost and satisfactory customer service, our products have been exported to many countries.

We meet all aspects of customer requirements:

1) Mould temperature: 60-80 C
2) Barrel temperature:front section: 220-260°C
Middle section: 290~310°C
Back section: 300--320°CNozzle: 290~300°C
3) Injection pressure: 60-70Mpa
4) Injection speed: medium
5) Injection time: according to the size of the part, it is better if the part fills the mould and the surface is basically cooled and shaped.

The most common processes within the CNC machine shop are the planning of materials, creating CNC programs, the actual manufacturing process, as well as the quality control of parts that are machined.

Dimensional accuracy

The accuracy of dimensions is crucial before distributing machined components to clients. Typically, during the process the dimensions of each feature are checked after the machining procedure is finished. To ensure quick inspection using gauges to measure the dimensions are usually attribute gauges (go or no-go gauges) or variable gauges (calipers micrometers, micrometers, and measurement of height). In the end, a coordinate measurement machine (CMM) is utilized for the final and thorough quality check before delivering the completed machines to customers.

Finishing the surface and Structural Integrity

For precise custom-made machined parts the last attributes that are inspected in the machined component are the surface finish as well as the structural quality. Surface finish can be typically assessed using profilometers. However structural integrity is assessed using non-destructive methods that look for cracks or voids within the material that could be present during the process of machining.
