What is Plastic Injection Molding?
Injection molding is the most cost-effective method for mass-producing plastic components. The process involves injecting molten plastic into a mold and then ejecting the solidified part. Since the same mold tool is used for each part, injection molding ensures consistent quality in every piece. Compared to CNC machining or even 3D printing, injection molding offers the widest range of materials, colors, cosmetics, polishing, and surface textures.

Plastic injection molding
Injection molding is a high-pressure manufacturing process that involves injecting thermoplastic materials into a mold. It is the ideal choice for high-volume production, offering cost-effective and efficient manufacturing solutions.
Plastic and metal Insert molding
Insert molding is an injection molding process that works especially well for parts that have threaded holes. It can also help you create better wheels, pulleys, fan blades, and other similar parts.
Plastic and LSR Over-molding
Plastic and LSR (Liquid Silicone Rubber) over-molding is an innovative manufacturing process that combines the advantages of both plastic and silicone materials to create high-performance, multi-material parts. In this process, a plastic substrate is first injection-molded, and then a layer of LSR is applied over specific areas of the plastic part.
Large Part Injection Molding
Large part injection molding is a specialized manufacturing process used to produce oversized plastic components and parts. This technique is particularly suitable for creating large and complex parts that are difficult or impossible to produce using traditional molding methods.

Plastic Injection Molding Process
Siliconepartner specialize in delivering high-precision, complex plastic parts with quick turnaround times. The plastic injection molding process is straightforward and user-friendly, enabling the production of custom prototypes and end-use parts within just 15 days. The injection machine is composed of three key components: the mold, the injection unit, and the clamping unit. Here are the steps to customize your plastic products through the plastic injection molding process.
Step1: Injection molding
The Thermoplastic resins are loaded into the injection machine barrel by our operators. They will undergo melting, compression, and injection into the mold under predetermined conditions.
Step2:Demolding
Thermoplastic resins cure in the mold. After the thermoplastic materials are cooled, the parts need to be demolded. Once demolding is complete, the finished parts will fall into a loading bin.
Step3:Deflasing
Our quality control team will meticulously inspect each product, using a testing machine to identify any with rough edges. They will then trim these edges off, ensuring the plastic products are clean and neat.
Application Industries For Plastic Injection Molding
1. Automotive Industry: Plastic injection molding is extensively used in the automotive sector for manufacturing components such as dashboards, bumpers, interior trims, and engine covers. The process allows for the production of lightweight, durable parts with complex geometries, which are essential for modern vehicle design.
2. Consumer Electronics: This industry relies heavily on plastic injection molding to produce various components like housings, connectors, and structural parts for devices such as smartphones, laptops, and home appliances. The precision and scalability of injection molding make it ideal for high-volume production with tight tolerances.
3. Medical and Healthcare: Plastic injection molding is crucial in the medical field for producing sterile, high-precision parts such as syringes, medical device housings, and implants. The ability to use biocompatible and medical-grade plastics ensures that the components meet stringent health and safety standards.
4. Packaging Industry: In the packaging sector, plastic injection molding is used to create a wide range of containers, caps, lids, and other packaging solutions. The process provides the flexibility to produce high-quality, cost-effective packaging with various shapes, sizes, and material properties to meet specific market demands.
FAQs
Q: How Much Does Plastic Injection Molding Cost?
A: Learn how to lower the manufacturing costs of your custom parts with our injection molding guide, which covers essential factors affecting expenses, including tooling, materials, and production processes.
Q: Who Owns the Injection Mold?
A: Customers own all custom tooling they develop, while reusable proprietary components created by the manufacturing partner (MP) become the MP's property. Custom tooling remains at the MP's facility for a minimum of two years, with the option for extension if needed. Transfers to other locations are possible at the requester's expense.
Q: What Is the Process after Ordering?
A: Upon receiving the order, our manufacturing engineers review the statement of work. A case manager is assigned, and a suitable manufacturing supplier is selected. We create a thorough DFM report for approval. After approval, tooling and mold production begin. T1 samples are produced and sent for approval. Upon approval, the rest of the parts are manufactured.
Q: What ISO Certifications Do You Have?
A: Having both ISO 9001 and IATF 16949 certifications showcases our dedication to maintaining rigorous quality management practices and meeting the stringent requirements of our client’s industry.
