What is Custom Plastic Injection Molding?

Custom Plastic Injection molding is an efficient process of manufacturing custom plastic parts in any quantity, small, medium, or large. This involves the use of molds where the molten plastic material is poured and allowed to cool and harden to the required shape. This cycle is repeated hundreds or even thousands of times, which enables the production of several custom plastic parts at once. The cost of the custom mold is distributed over the number of parts manufactured, which makes the price per unit only a few $$s or even less. Custom plastic injection molding guarantees uniformity of the parts produced and has more material, color, cosmetic, polish, and surface finishing possibilities than 3D printing or CNC machining.

Sincere Tech is a specialized custom plastic injection molding company that provides prototypes and short-run and volume-run custom molding services. We offer custom plastic parts that meet your exact design requirements while being affordable. Our professional engineering department consults with every injection molding quote offered to customers to facilitate an easy transition from design to production.

Customized Injection Molding Costs

The price of customized injection molding is not standard and depends on how you engage our services and your project specifications. Generally, the cost can be broken down into two main components: the total cost of production and the price of the mold or the tools that are used in the production process.

Tooling Cost/Injection Mold Cost/Rapid Tooling Cost

Making the custom mold entails other costs that are not included in the total cost of production. The custom mold cost is paid at the beginning of the injection molding process and depends on the blueprint design of the mold. The time it takes to create a mold depends on the mold’s design and its intricacy. Plastic parts production is initiated only after the mold has been made or finalized. There are two types of manufacturing processes for mold creation: rapid manufacturing and conventional manufacturing, with different prices and production approaches.

Key Factors Influencing Customized Injection Molding Cost

The following steps are involved in customizing injection molding molds.

Design Blueprint and Complexity

The level of preparedness and the level of complexity of the product design is a key factor that influences the costs. The complex designs require more complex molds and take more time to make.

Raw Materials

The cost is determined by the type and quality of the material used on both the plastic products and the mold. In general, it can be stated that the acquisition of higher-grade materials is more costly than that of lower-grade ones.

Manufacturing Technology

The choice between rapid manufacturing and traditional manufacturing technologies is based on cost. Although rapid manufacturing is faster, it is expensive.

Tooling Process

The following are some of the factors that can be associated with the tooling cost: the design of the mold, its features, and the material used to construct it.

Project Requirements

The cost may also be affected by schedules and certain specifications of the project. This may force the client to order rush services which are usually costly.

Additional Processes

Other operations such as branding, pad printing or any other special operations will also add to the price.

The cost of injection molding is determined by the design of the product, the quality of the material used, the technology used in production, and other factors of the project. At Sincere Tech, we offer tailor-made solutions to your needs, whether it is a one-off or a batch run.
