The Cost of Plastic Injection Overmolding Process

The cost of plastic injection overmolding process is relatively high, mainly due to its special production process and required equipment, materials and other factors. The following are the main components and influencing factors of the cost of plastic injection overmolding process:

1、 Mold cost

Secondary mold requirements: To achieve secondary injection molding, two molds are required, one for the first injection molding and the other for the second injection molding. The manufacturing and design costs of molds are the main components of manufacturing costs, especially when the product shape is complex and dimensional accuracy is required, the mold cost will be higher.

Mold materials: The selection of mold materials also affects costs, such as steel molds, aluminum alloy molds, etc. The cost and performance of different materials vary.

Mold maintenance: Regular maintenance and upkeep are required during the use of molds to ensure their accuracy and lifespan, which is also an undeniable cost.

2、 Material consumption

Plastic materials: During the secondary injection molding process, two or more different plastic materials need to be injected. Therefore, compared to single injection molding, secondary injection molding requires more plastic material consumption and higher costs.

Water nozzle material treatment: Whether the water nozzle material (waste) generated during the injection molding process can be recycled will also affect the cost. If it can be recycled, it can reduce material costs; If it is not recyclable, additional processing fees will be required.

3、 Equipment investment

Dual injection molding machine requirements: To achieve secondary injection molding, a dual injection molding machine or an injection molding machine with multi station conversion function is required. These devices have high investment costs and require professional personnel to operate and maintain.

Equipment depreciation: The depreciation cost of injection molding machines and other equipment is also a part of the cost. As the usage time increases, the performance of the equipment will gradually decline, requiring more maintenance and upkeep costs.

4、 Other costs

Labor cost: During the injection molding process, operators, technicians, and management personnel are required, and their salaries and benefits are also part of the cost.

Energy cost: Injection molding machines require energy consumption such as electricity during operation, and energy cost is also an important part that cannot be ignored.

Transportation and packaging costs: The products after injection molding need to be packaged and transported, and these costs also need to be included in the total cost.
