Injection Molding Processes

Injection molding is a six-step procedure that offers large-scale, reasonably priced, and high-quality plastic parts. The process starts when plastic pellets are put into the machine after selecting the required material. The pellets are then heated until a resin is formed by their melting. A mold is then filled with the molten resin.

The component then cools and hardens inside the mold. Ultimately, the cycle is finished when the part is ejected. Because of how quickly this process can be done, injection molding is a great option for reliable, mass production.

With our streaming prototype and production molding expertise, our premium custom plastic mold service guarantees that your parts are manufactured precisely as required without sacrificing design integrity.

We prioritize our customers' needs by matching them with the best-priced injection molding services. We expedite the process from design to manufacturing with savvy guidance and our committed project managers governing every order

What You Need to Know About Injection Molding

Advantages Disadvantages

Superior Performance for Large-Scale Manufacturing: Large quantities of identical parts can be produced quickly with injection molding, which makes it a very effective method for mass production.

Costly Initial Tooling Costs: For low-volume production runs, the upfront cost of designing and manufacturing the molds can be prohibitive.

Accuracy and Reliability: The procedure is perfect for tricky or intricate items, guaranteeing tight tolerances and uniform quality across each unit.

Extended Lead Time for Manufacturing: It can take weeks or months to create and perfect the molds, which delays the release of new products onto the market.

Material Flexibility: An extensive range of plastics to select from, such as elastomers, thermosets, and thermoplastics, provides flexibility in material attributes, including strength, flexibility, and heat resistance.

Limited Flexibility in Design Post-Mold: Once the mold is made, modifications can be expensive and time-consuming, reducing the flexibility of further design iterations.

Decreased Wastage: Injection molding reduces material waste because of its efficient molding procedures and capacity to reuse extra plastic.

Material-Specific Restrictions: Certain materials, especially those with extremely high melting temperatures or unique mechanical qualities, are inappropriate for injection molding.

Minimal Labor Costs: Once set up, injection molding is highly automated, minimizing manual labor and lowering production costs.

Large Run Requirement: Large production runs are usually needed to justify the high initial tooling costs, which may not be feasible for many types of organizations.

Mold Cavity Tolerances

Our ability to maintain mold cavity tolerances as close as +/- 0.05 mm, or +/- 0.002 in, guarantees accuracy and precision in every product we manufacture. These incredibly tight tolerances are essential for sectors where even minute variations might affect the functionality of a product. We ensure consistency throughout massive manufacturing runs by upholding such strict standards, ensuring every component fits precisely into your assembly without requiring any adjustments. It is possible to request tighter tolerances, but doing so could result in higher tooling costs due to the need for more sampling and grooming.

Available Machines

We have family molds, multi-cavity molds, and single-cavity molds with press tonnages ranging from 50 to 2800 tons.

Part to Part Repeatability

We offer a part-to-part repeatability of +/- 0.002in or +/- 0.05mm.

Mold Types We Offer

We provide quality steel and aluminum molds with service lives of 1000 cycles, 5000 cycles, 30,000 cycles, 300,000 cycles, and more.

Our Inspection and Certification

We will submit FAI (First Article Inspection) as per ISO 9001 for our golden samples.

The only factors that matter are the part size, geometric complexity, and mold design. The standard tolerance range for common molded parts is as follows:

Parts Types Tolerance (Inches)
Simple Injection Molded Parts +/- 0.001 to 0.003
Geometrically Complex Parts +/- 0.005 to 0.01
Large molded parts +/- 0.01 to 0.02

How long does it take to make molded parts?

The size, intricacy of the design, and specifications of the product all affect the cycle of the injection molding process. With state-of-the-art injection molding equipment, the production of molded parts normally takes a few seconds to two minutes. But compared to simple parts, complicated parts require a longer cycle time. Furthermore, the intricacy of the finishing and assembling procedure affects how long the manufacturing process takes.

What are the types of injection molding processes?

Injection molding service providers employ various techniques for an extensive spectrum of uses. The following are some typical kinds of injection molding procedures:

  • Insert Molding
  • Gas-assisted Molding
  • Micro Injection Molding
  • Multi-Shot Injection Molding
