    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

      At JOBR, our experienced team produces high-quality injection-molded products. We use custom plastic injection molding with our rapid tooling capabilities, allowing us to create detailed custom parts quickly and efficiently. Our plastic injection molding technology allows us to use a wide range of materials and finishes to suit the needs of any industry or application.

    Addition Injection Molding Options

      Besides the basic plastic injection molding services, we also offer two variants of the process – overmolding and insert molding. Both of these can be useful in specific situations.



    Overmolding uses plastic injection molding to create a part from multiple materials. This process adds an injection-molded layer of material over an existing injection-molded workpiece. The overmolding process produces chemically bonded parts made using multiple materials.

    Overmolding is often cheaper and more effective than other manufacturing approaches that require creating and assembling component material parts separately. The process can also be used to build layered parts from scratch or to add a resistant outer layer to existing plastic parts and tools, providing a more rugged exterior. 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 and does not have to be produced via 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. Insert molding is also frequently used to create products that incorporate bushings, clips, and fasteners.

    Plastic Injection Molding Production Process

    We Process for JOBR Tech's Rapid Prototype Service:

    RFQ Submission

    To initiate the plastic injection molding process, please submit your RFQ (Request for Quotation) to us. This allows us to provide you with an accurate quotation based on your specific requirements for custom plastic injection molding and plastic insert molding.

    Quotation & Design Confirmation

    Once you have received and confirmed the quotation, we move forward with the next step. Our team conducts Design for Manufacturability (DFM) analysis and provides mold drawings for your approval. This ensures that the design is optimized for efficient and precise plastic injection molding.

    Mold Drawing Confirmation & Production

    Upon your confirmation of the final mold drawings, we begin the production process immediately. Our skilled technicians utilize state-of-the-art equipment and techniques to manufacture the molds required for plastic injection molding.


    After thorough quality checks to ensure the accuracy and integrity of the manufactured parts, we proceed with the assembly and packaging stage. Once completed, we arrange for prompt and secure shipment of the finished products.

    Quality Assurance

    At JOBR Tech, we take full responsibility for ensuring that your parts are manufactured to our stringent quality standards. Through rigorous quality control measures and inspections throughout the plastic injection molding process, we guarantee the highest level of product excellence.

    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 service process? What are the advantages in the 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 company?

    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.
