Understanding Different Types of Injection Molding

Injection Molding’s Role in Mission Critical Manufacturing

High-quality injection molding plays an important manufacturing role across industries. This process is relied on to repeatedly and reliably produce parts with tight tolerances that provide consistent long-term performance.

By utilizing our expertise and state-of-the-art technology, TenX Manufacturing can produce cost-effective tooling and molded parts at scale to meet your performance and dimensional requirements. Explore the possibilities of injection molding to find the right method for your application.

How Injection Molding Supports the Full Product Lifecycle

Injection molding describes a wide range of production solutions, rather than a one-size-fits-all process. There are solutions appropriate for all stages of product development, from prototyping to production runs, that can evolve throughout the cycle. For example, tooling and creation in the early stages will be lower volume and less cost effective than finished designs being created at mid- or high-volume rates. However, because TenX’s expert engineers provide multiple types of injection molding services, there is minimal risk in using injection molding. In fact, injection molding can be a viable option for all stages of production.

Prototype Injection Molding for Design Validation and Early Testing

In the prototyping phase, injection molding offers many advantages, including:

  • Using the same materials that are intended to be used in production
  • Faster iteration compared to production tooling
  • High levels of detail
  • Quick turnaround times

What sets prototype injection molding apart from other prototyping methods is its ability to replace or complement 3D printing or CNC-machined parts that might otherwise be more expensive or take longer to produce. Parts that will be produced with injection molding also benefit from the process during prototyping because it makes it easier to discover design or material issues early in the creation process.

Bridge Injection Molding: Transitioning to Production

When your products are ready to go beyond prototyping but aren’t ready for full-scale production, bridge injection molding is what your parts need. This process offers many positives, including:

  • High-quality production
  • Quick turnaround times
  • Cost-effective tooling
  • Design validation to test part performance, compatibility and market readiness

Bridge injection molding is ideal for performing pilot builds or meeting early customer demand, while also allowing you to gather real production data before scaling up to full-volume runs.

Low-Volume Injection Molding for Controlled Early Production

This process moves beyond the iterative nature of prototypes and the volume of bridge production, allowing for a cost-controlled run of parts before full ramp-up to high-volume production. What makes low-volume injection molding unique is the combination of quality and controlled quantity of parts, allowing for companies to manage their risk by slowly scaling up production.

High-Volume Injection Molding With Production Tooling

Depending on the project, TenX designs and builds production tooling in-house or through trusted partners. Our high-volume injection molding services harness the power of automation and process validation to produce parts at scale ranging from 100,000 to millions of units. From consumer electronics to automotive parts, packaging, medical components and more, high-volume injection molding can be used to create products for a huge range of industries and applications where tooling and repeatability are required.

Insert Molding to Strengthen Parts and Simplify Assembly

Insert molding uses pre-formed inserts that are placed in a mold and then plastic is injected around the object. This process allows for integrating rigid materials, such as ceramics or metal, into injection molded parts. Among its many benefits, the insert molding process provides:

  • Improved structural integrity and resilience
  • Reduced assembly time
  • Heightened consistency
  • Various performance improvements with materials that are conductive or resistant to heat

Multi-Shot Molding for Performance Functionality and User Interaction

What sets the multi-shot molding process apart is its use of multiple materials to mold a single part. This method is ideal for products that need functionality boosts like improved grip, sealed surfaces, thermal stability, impact resistance or chemical resistance. It is also helpful for heightening the aesthetic characteristics. Some benefits of multi-shot molding include:

  • Material combination versatility, including hard plastics with soft elastomers
  • Integrated, complex geometries that limit need for additional assembly
  • Colors can be customized without extra painting or finishing after molding
  • Streamlined production process

If your parts demand ultimate durability and thoughtful ergonomics for all kinds of environments, multi-shot molding is a valuable manufacturing option to explore.

How Injection Molding Compares to Other Manufacturing Processes

There are various manufacturing processes that should be considered when planning your production runs. Services like urethane casting can produce similar types of products, often for even less than injection molding. However, urethane casting is not particularly well-suited for high-volume production runs, so it isn’t recommended for any projects that call for more than a few hundred parts. 3D printing, on the other hand, can provide even more intricate details than injection molding, but for high-volume runs, injection molding is more efficient. All in all, injection molding is the right choice for:

  • High-volume production runs
  • Prototype or bridge production that require quick turnaround times before scaling up
  • Production-ready low-volume runs
  • Products that require overmolding or inserts
