Today, leading Chinese machine shops Swiss-style lathes and multi-pallet machining centers, which permit volumetric accuracy machining of parts on the order of precision Swiss machining. Top-tier machined parts China suppliers can achieve tolerances of up to 0.005mm.
Die casting specialists can produce the zinc, aluminum, and magnesium parts with high accuracy. Die casters in China are known for their high-quality thin-wall castings, which are in high demand by the electronics and automotive industry.
Stamping and metal fabrication shops can produce sheet metal parts on high volume. Many of them combine this with in-house tool making and provide complete turnkey solutions.
The competitive edge of Chinese machined parts China suppliers is in precision machining and secondary operations such as finishing anodizing, plating, and assembly, which results in ready-to-install parts.
China’s services in plastic moulding
The scope of service offered by China’s plastic moulding China industry is as diverse as:
The production of plastic parts is dominated by the injection moulding plastic suppliers ranging from 50-ton desktop machines to 4,000-ton automotive dash board producers. They utilize multi-cavity and family moulds which aid in mass production, consequently bringing the cost of each part to remarkably low prices.
Specialists in blow molding manufacture plastic containers and bottles. Many Chinese sellers offer in-house services like silk screening and labeling.
Open air rotational molds create large hollow structures such as tanks and playground equipment. Although not as popular as injection molding, a number of Chinese suppliers focus on this area.
Some of the best plastic moulding China companies focus on offering a full range of services like choosing materials, analyzing Design for Manufacturing (DFM), and prototyping, which turns them into true partners and not just suppliers.
Validation confirms that consistency within a production process is maintained throughout operational activities. When looking into suppliers for machined parts China and plastic moulding China, check for monitored process controls and documented statistical process controls for critical parameters on machined parts.
Cost Structures and Pricing Models
Why Get a Quote for machined parts China and plastic moulding China without understanding the pricing models? These documents explain the various pricing structures offered:
For plastic components, the tooling costs are the most expensive. For plastic injection molds of medium complexity, a Chinese vendor may quote 5,000−5,000−15,000, whereas domestic suppliers may charge 20,000−20,000−50,000. For parts that are machined, these do not require much tooling unless specific jigs and fixtures are needed.
Pricing for parts and items is based on the order volume. An example of pricing is the machined aluminum bracket. It may go for:
- $15/part at 100 pieces
- $8/part at 1,000 pieces
- $5/part at 10,000 pieces
Also, the same logic applies for plastic moulding China, where the cost per unit decreases significantly from the initial 60-70% between the prototype and production runs.
Adding secondary operations increases the cost of a product; however, it may still provide considerable value. Anodizing, painting, and assembly are examples that could offer value; particularly if the value is added cheaper than if those processes are done in the domestic country.
Locating and Assessing Dependable Vendors
It takes effort to find reliable partners in machined parts China and plastic moulding China:
Through Supply Base Solutions, you can check thousands of suppliers. Narrow down to those with:
