How much does injection molding cost cheapest in China?


China’s injection services are widely recognized for their quality and competitive price structure. It provides affordable molding services due to advanced machinery, expertise and cheap labor. Injections are one of the more expensive to manufacture in terms of initial investment. Most of the budget is spent on mold making. This pricing scheme is not entirely suitable for China’s injection molding costs, which are optimized in every aspect. Injection molding prices in China are lower than in other regions. In this article, let’s explore what is the cheapest injection cost in China?

What is injection molding?

Injection molding is a manufacturing process involving the use of injection molding machines to produce products from thermoplastic or thermosetting materials. The process involves melting the material and then injecting it into a mold in the shape of the desired product. Once the material is cooled, the mold opens and the finished product is ejected.

Injection molding is a high precision and efficient process for producing a variety of products ranging from plastic toys to medical equipment and auto parts.

China injection molding cost

When it comes to the cost of custom injection molding in China, prices may vary depending on the scale of production and the quality of work required. The cost of injection molding in China will be between $1000 for small-scale production and $12000 for mass production, depending on the quality of the work. Outsourcing to large-scale processing in China may be a cost-effective alternative compared with other methods.

Why is China invincible in the field of injection molding?

There are three main reasons why China is leading in the injection molding industry: manufacturing infrastructure, technological advances, and skilled but low-cost labor. Its large-scale infrastructure dramatically reduces production costs. This is possible because Chinese companies can meet large-volume production demand. China’s continuous investment in advanced technology plays an important role in ensuring efficient and high-quality production. At the same time, the staff skillfully manage these advanced processes, contributing to the efficiency of the industry.

In addition, China’s injection molding industry has largely benefited from government support and global supply chain integration. Government policies and subsidies promote industry growth, while integration into the global markets is good for exports.

Injection molding cost example

Low yield

Low-volume production can be thought of as anywhere from a hundred to a few thousand parts for any product. For these low-volume applications, manufacturers often produce the molds in-house and form the molds themselves. for
For low-volume production, manufacturers use 3D printing polymer resin to make molds because it is cheap and does not require long production cycles. The entire production process takes approximately 3 days to produce finished parts. For a 100-part run, we assume the following parameters:

  • Number of parts = 1,00
  • Mold cost = $1,00
  • Raw material cost per part = $0.50
  • Total cost of materials = $50
  • Labor cost per part = $4
  • Total Labour costs = $4,00
  • Total cost of the injection procedure = $550
  • Cost per component = $5.50

Medium volume production

Medium volume production ranges from five thousand to tens of thousands of parts. For this scale of production, manufacturers typically outsource mold production and molding processes.

For medium volume, we assume a unit production cycle of 6,000 units for the same part.

  • Number of parts = 6,000
  • Mold cost = $2,000
  • Cost of material per part = $0.6
  • Total material cost = US $3,600
  • Labor cost per part = $2
  • Total Labour costs = $12,000
  • Total cost of injection molding = $17,600
  • Cost per component = $2.93

Mass production

High-volume production involves hundreds of thousands of parts. For comparison, let’s assume we produce 100,000 parts of the same type.

  • Number of parts = 100,000
  • Mold cost = $25,000
  • Cost of material per part = $0.50
  • Total cost of materials = $50,000
  • Labor cost per part = $1
  • Total labor costs = $100,000
  • Total cost of injection molding = $175,000
  • Cost per component = $1.75

It can be seen that the injection molding cost per part is significantly lower in high-volume production. Therefore, high-volume projects are the most cost-effective projects for injection molding.
