What is Injection Molding?

Injection molding is a manufacturing process that mass-produces thousands of identical plastic components. It involves injecting the molten material (usually thermoplastic and thermosetting polymers) into a mold fitted into the machine.

These molds are precision-machined to match the shape of the final product. They also have cooling lines that reduce the solidification time by circulating water or oil from an external temperature controller after material injection.

Besides plastics, the process can make metal (die-casting), glass, confections, and elastomer parts.

Quick Mold

Rapid Mold Process: We employ CNC rough machining, EDM (electrical discharge machining), mold fitting, mold debugging, mold assembly, mold installation, and injection molding to produce the mold and product swiftly.

Next, the process involves removing injection molding residuals, retrieving the finished products, and trimming residuals. We’ll finish off the process with a manual quality inspection as well as a 3D inspection. The mold and product can be completed in 10 days.

Processing Accuracy: ±0.1 mm/100 mm
Injection Molding Tonnage: 80 to 3000 tons

Materials:

✔️ PET (Transparent)

✔️ POM

✔️ PC (Transparent, Opaque, Medical Grade, Flame Retardant)

✔️ HIPS (Natural Color, Modified)

✔️ ABA (Transparent)

✔️ TPU (Transparent, Opaque, Various Hardness)

✔️ TPE (Transparent, Opaque, Various Hardness)

Silicone Compound Mold (Vacuum Compound Mold and Low-Pressure Injection Mold)

Silicone Molding Process: This process starts with fixing the mold support, mixing silicone rubber, and silicone injection molding. Then, we’ll move on to vacuum treatment, initial demolding, and mold closure.

Next, we’ll inject the material, which is followed by demolding and removing burrs. Finally, we’ll conduct a manual inspection and 3D inspection. We can produce 200 pieces in 5 days.

Processing Accuracy: ±0.2 mm /100 mm

injection molding advantages disadvantages

Advantages

  • Easy to scale production to fabricate multiple parts, with the cost of production lowering the more you scale
  • Can be used to mold products with different materials simultaneously, as well as plastics in multiple colors
  • Easy to design and manufacture intricate designs with complex geometrical shapes
  • Reduces material wastage, making it more eco-friendly
  • Produced parts need minimal finishing after mold ejection to create the final product or appearance
  • Produces identical parts that lead to part reliability and consistency during high-volume production
  • Fast production times
  • Requires relatively little manual labor, which lowers production costs

Disadvantages

  • High up-front costs of the injection molding machines
  • Expensive to produce parts in low volumes
  • Not ideal for molding large parts as single pieces
  • Requires high standards and skilled designers to create prototypes and refine them to get the final mold
  • Prototype creation can be time-consuming and costly

Applications of Injection Molding

  • Plastic car parts (e.g., bumpers, dashboards, grills)
  • Consumer plastics (e.g., bottle caps, smartphone cases, toys, pocket combs, storage containers, etc.)
  • Medical devices (e.g., syringes, dishes, trays, valves)
  • Electronic components (e.g., enclosures, connectors, protective sleeves, etc.)
  • Plastic furniture parts (e.g., chairs, small tables, seat covers, cushions)
  • Wire spools

Take a Factory Tour!

OurPCB Shijiazhuang opened in 2007. Today, this factory spans over 6,000 meters in total, is equipped with 5 SIEMENS SMT lines, and has 200 employees. 90% of the business at our factory in Shijiazhuang is for advanced PCB assembly.

We went on to build our second factory in Shenzhen in 2017. This factory is about half the size of Shijiazhuang, but it boasts 7 YAMAHA SMT lines, X-ray, and AOI. It’s dedicated to standard assembly service and employs 110 people.

In 2014, we opened OurPCB in Melbourne, Australia, to provide services to our English-speaking customers across the world.
