For many OEMs, multi-material injection molding is a smart and versatile solution to producing complex components and parts. The ability to incorporate multiple polymers, metals and other non-plastics into the molding process to accommodate threaded holes, inserts, lenses, etc., simplifies assembly and generally enhances end-product performance.

Almost any reasonable design looks good on paper or even as a prototype, but that doesn’t mean it’s a sure thing when it comes to manufacturing it. On the other hand, using Design for Manufacturability (DfM) to improve part design, injection molding processes and material selection ensures a product or component can be manufactured in a streamlined, efficient, validated, and repeatable way — saving time and money.

There is more than one way to produce an effective plastic injection-molded part. The question is: is complex tool design the answer or is it better to utilize machining technologies to complete the task?

Snap-fit designs can be an effective way to replace fasteners/hardware in injection-molded plastic parts or products. For most applications, snap-fit connections are the simplest and most cost-effective way to assemble two parts — making them ideal for high-volume production. The quick and easy connections help reduce the risk of improper assembly, which occurs more frequently in applications that require more components (fasteners) and tools.

There are many steps that go into making a high-quality plastic injection molded product or part, many of which happen before production even begins. The quality planning and assurance process is one of these crucial steps, and it involves rigorous analysis to ensure the best possible design, materials, and production processes are being used for your application. Having a team of experienced quality engineers to plan and oversee this phase is critical for efficient, optimized production, and at Kaysun, we don’t cut any corners when it comes to quality assurance (QA) or testing.

Are you considering injection molding for the production of a current or upcoming plastic parts project? If so, you came to the right place. Injection molding is the ideal process for the production of a wide range of complex plastic components, and can benefit OEMs across many different industries. It’s consistent, affordable, and creates durable, high-quality plastic parts that can withstand just about any environment.

In many industries, injection molding is a proven solution to complex plastic part engineering and design challenges. However, not all projects are well-suited for the process and will not fully benefit from injection molding efficiencies.

When it comes to designing and launching a new product or component, there are three things design engineers can always count on:

Complex injection molding is relied upon in a number of industries to make the production of plastic parts and products more efficient. Crucial to realizing this efficiency though, are design and manufacturing process improvements that allow for the consolidation of multiple existing parts into a single complex injection molded plastic component. Below are examples that demonstrate the benefits of part consolidation and how to achieve them:
