    Plastic Injection Molding

    Manufacturing plastic parts in volume, we offer a wide range of part complexities and sizes to create detailed custom parts quickly and efficiently.

    Plastic Injection Molding Services

      Plastic injection molding is perfect for manufacturing high volumes of the same parts. At JOBR, we produce high-quality injection-molded products from a wide range of materials and finishes. With advanced plastic injection molding technology, we can satisfy your needs in any industry and application in a relatively short time.

    Addition Injection Molding Options

      Besides the basic plastic injection molding services, we also offer two variants of the process - overmolding and insert molding. These methods are useful in specific situations.



    Overmolding is a unique custom plastic injection molding process that chemically bonds multiple materials into a single part.

    Overmolding is often cheaper and more effective than other manufacturing approaches that require creating and assembling component material parts separately. The overmolding process can also be used to build layered parts from scratch or add resistant outer layer to existing plastic parts and tools. Toothbrushes consisting of a solid plastic body and rubberized grip are a common example of an over-molded product.



    Insert molding is similar to overmolding, but the substrate is not necessarily plastic. It does not require injection molding. For example, insert molding can be used to add a plastic coating to a pre-fabricated metal part.

    Common parts made by insert molding include sharp handheld tools, such as scalpels, which consist of a metal blade partially housed within a plastic handle. Plastic insert molding is also frequently used to create products that incorporate bushings, clips, and fasteners.

    Plastic Injection Molding FAQs

    What is Plastic Injection Molding?

    Plastic injection molding is a manufacturing process that involves injecting molten plastic material into a mold cavity to produce a wide range of plastic parts and components. It is a versatile and efficient method used in various industries for mass production of plastic products.

    What is the Plastic Injection Molding process? What are the advantages in JOBR service?

    Service Process: First, we receive the customer's RFQ (Request for Quotation). Based on the RFQ, we provide a quotation. After the customer confirms the quotation, we proceed with DFM (Design for Manufacturability), mold flow analysis, and mold design. Once the customer approves the mold drawings, we begin the mold manufacturing process. After the mold is completed, we conduct trial molding and perform quality inspections. Finally, we assemble, package, and ship the products.

    Advantages of our service: Fast delivery, quality assurance, and customization of small batch production.

    What are the specific strengths of the JOBR?

    We have a management team composed of professional technical experts. With advanced mold technology and strong manufacturing engineering capabilities, we provide end-to-end services ranging from part development, mold design, injection molding, assembly, packaging, to delivery. We have extensive experience in custom production using engineering materials such as PEEK, PPSU, PBT, LCP, and PBT for injection molding.

    How does Plastic Injection Molding benefit product development?

    Plastic injection molding offers several advantages for product development, including:

    Design flexibility: It enables the production of complex shapes and intricate details with high precision.

    Cost-effectiveness: Once the initial mold is created, plastic injection molding allows for efficient mass production, reducing per-unit costs.

    Material options: A wide range of thermoplastic materials can be used in plastic injection molding, providing versatility in material selection for specific application requirements.

    Can JOBR Tech accommodate custom Plastic Injection Molding projects?

    Yes, JOBR Tech specializes in custom plastic injection molding projects. We work closely with our clients to understand their specific requirements and provide tailored solutions to meet their unique needs. From material selection to design optimization and production, we ensure the final parts are precisely manufactured to the desired specifications.
