What is the Cost of a Mini Plastic Injection Molding Machine?

Small injection molding machines, also known as mini plastic injection molding machines, have gained popularity among manufacturers and hobbyists alike due to their compact size, versatility, and cost-effectiveness. In this article, we will explore the cost considerations associated with mini plastic injection molding machines, focusing on the quotation range of machines with a tonnage of 30-80t.

1. Understanding the Quotation Range for Mini Plastic

Injection Molding Machines:

The cost of a mini plastic injection molding machine can vary depending on several factors, including the tonnage, features, quality, and brand of the machine. For machines with a tonnage range of 30-80 tons, the quotation range is usually within US$8,000-14,000 of the FOB price. It is important to note that these prices are indicative and can vary depending on individual suppliers, market conditions and specific demand.

2. Factors Affecting the Cost of Mini Plastic Injection Molding Machines:

Tonnage:

The tonnage of an injection molding machine refers to its clamping force.

How small can injection molding be

On average, the minimum wall thickness of an small injection molding part ranges from 2mm to 4mm (. 080 inch to . 160 inch)

As part size and dimensions increase, the complexity of design, engineering, and calibration required to construct, install, and process this 2-sided mold results in a significant increase in the cost of equipment, tooling and setup.

Small injection molding machine- Size Considerations

In theory, there is no limit to the size of products that can be manufactured through injection molding.However, in real life, plastic molding machines used to manufacture these components are limited in terms of the size of the components they can produce.

Before hiring a factory to shape for you, please inquire about the size limitations of small injection molding machine.

Small injection molding machine-Design Concerns

As mentioned earlier, most small plastic injection molding machine divide the mold into two metal parts.Therefore, things such as interlocks, undercuts, and thin and unsupported walls may not be formed the way you want them to be.

In addition, if your design does not have the correct draft angle and support, you may end up with warped parts.

Small injection molding machine-Ejectors and Cooling Lines

If you have any plastic molded parts, you may notice a faint line around the object. This is where the two halves of the mold intersect. You may also notice a rough spot on this line. This is a thin tube filled with plastic from the mold.

As the size of the parts increases, stronger molds and equipment are needed, and the production cost and delivery time of each part may also significantly increase. These increased capital expenditures will result in an increase in investment and management costs calculated in the piece price. The overall size capacity of injection molding machines is limited, but they can usually accommodate multiple parts in the mold structure. A smaller part size is equivalent to a larger number of parts manufactured per mold and mechanical cycle. A larger part size will reduce the number of parts that can be manufactured per mold and cycle.
