In the injection molding industry, the question of whether to use a cleanroom—and what standard it needs to meet—comes up frequently. The answer is never one-size-fits-all: it completely depends on your product's application and precision requirements.
The difference between an ISO 8 Class (100,000 level) cleanroom for general industrial parts and an ISO 5 Class (Class 100) cleanroom for medical implants is massive—in both technical requirements and investment cost.
Today, we'll break down the cleanroom standards for injection molding, helping you understand what level your product actually needs.
In the medical injection molding industry, leakage and poor overmolding adhesion are two of the most common and frustrating quality issues. For products like infusion devices, syringes, micropump systems, and other medical devices, these problems directly impact patient safety and are zero-tolerance defects.
Today, we'll provide a comprehensive analysis of how to solve these issues from three dimensions: root cause analysis → systematic solutions → validation methods.
In the injection molding industry, we frequently encounter this scenario: The product design looks great, the functionality is perfect, but when it's time to assemble two plastic parts by welding, problems appear—weak welds, air leaks, visible marks on the surface...
More often than not, these issues don't originate from the welding process itself. They start at the design stage of the injection molded parts.
Today, let's discuss: If your product requires ultrasonic welding, what design details must you consider before the mold is made?
Two-shot (2K) injection molding creates superior products by combining two materials in a single cycle. But how does the mold physically make this happen? The secret lies in the mold’s movement. Here, we break down the three main 2K mold structures that make complex, bonded multi-material parts possible.
READ MOREThink about the last time you held a high-quality power tool, a sleek remote control, or a premium toothbrush. Notice how the hard plastic seamlessly merges with soft, grippy rubber in one perfect piece? That's not glue or assembly — that's the magic of two-shot injection molding (also called 2K molding).
READ MOREMulti-material molding represents the pinnacle of injection molding integration. It consolidates functions and aesthetics—traditionally requiring multiple processes and assemblies—into a single mold and production cycle. This is not merely an efficiency gain; it enables products that are impossible with single materials alone.
This guide provides a panoramic view of the field, dissecting the principles, advantages, and boundaries of each mainstream technology.
