What Is Plastic Injection Molding?

Plastic injection molding is a highly efficient and effective manufacturing process that can quickly produce intricate geometrical shapes for custom parts and products. It is the preferred process for companies looking to produce repeatable parts with strict mechanical requirements. The process involves filling a mold tool with liquid plastic resin under high pressure. The tool may have a single cavity or hundreds of cavities to produce unlimited numbers of parts. Trust Yumar mold to deliver exceptional results using the latest injection molding technology.

Injection Moulding Processes

 

We can deliver your custom plastic injection moulded parts in as fast as 1 to 90 days, depending on the complexity and volume of your order.

At Yumar mold we offer plastic injection moulding, liquid silicone rubber (LSR) moulding, overmoulding, insert moulding, prototyping and on-demand manufacturing to ISO 9001 quality standards.

Make the move from prototyping to on-demand manufacturing for affordable, high-quality moulded parts within days. Better yet, your prototyping tool is free once you shift to an on-demand manufacturing tool. What’s more, working with a single supplier that provides free design consultation services will considerably speed up the manufacturing process. This allows for greater supply chain flexibility and ensures more consistent parts, making qualification significantly easier.

Tooling Materials

Before starting injection molding for low or high-volume production, high-tolerance CNC machined tooling is requisite. The materials used for CNC tooling are:

Tool Steel: P20, H13, S7, 718, 718H, 738, NAK80, S136, S136H
Stainless Steel: 316, 301, 303, 304, 420, NAK80, S136, 316L
Aluminum: 6061, 5052, 7075

Plastic Materials

With an extended range of plastic materials, you can choose what fits your needs perfectly. Each material has qualities that include heat resistance, impact strength, wear resistance, and many more.

  • Impact resistant: ABS, PMMA, PVC, PE, PC
  • Wear-resistant: POM, PEEK, UHMW
  • Dimensional stability: PBT, ABS, HIPS, PPS
  • Chemical resistance: PEEK, PP, PBT, PA, PE, LDPE
  • Rubber like: TPU, TPE, Silicone
  • Cost-efficient: PP, HDPE, LDPE
  • Cosmetic: ABS, PC, HIPS

Additives and Fibers

We incorporate additives and fibers to enhance the quality and esthetics of standard plastic materials. The process increases the functionality and performance of the molded product.

  • UV absorbers
  • Colorants
  • Glass fibers
  • Flame retardants
  • Plasticizers

Injection Moulding FAQs

Injection moulding is plastic manufacturing process that can produce high quality parts at scale. It’s typically used for low- to high-volume production but our aluminium tooling can also make prototyping runs economical.

  • Low cost at higher volumes
  • Exceptional part cosmetics and surface finish
  • Repeatable
  • Complex parts
  • Low scrap rate
  • Large selection of thermoplastic and thermoset materials

Injection moulding is widely used for plastic part production in medical, consumer, and automotive industries. Typical parts include:

  • Housings
  • Brackets
  • Gears
  • Single-use medical parts
  • Electrical connectors
  • Syringes
  • Containers

Our moulds start from $1000, however, because of the initial capital investment in tooling, injection moulding makes sense for higher volumes of parts. Our mould costs will vary depending on part geometry and complexity. Other factors that will impact injection moulding cost are lead times and material.

Yes, we offer a production tooling option called on-demand manufacturing. This tooling option provides several benefits: lower piece part price, multi-cavity capabilities, guaranteed tooling for the life of the project (we will cut a new tool if it wears out), and first article inspections.

There are high-volume applications where it is better to choose our ODM offer using aerospace-grade aluminium tooling and others where it makes more sense to opt for steel moulds – speak to our application engineers for advice.

The production cycle mainly depends on the complexity of the mold and the error requirements. We will produce high-quality, ultra-durable, high-precision products and molds for you as soon as possible.

We have wide selection of more than 100 thermoplastic and thermoset materials. And if you’re looking for alternative material options, check out our guide to resin substitutes for ABS, PC, PP, and other commonly moulded plastics.
