Every Undercut Comes With a Cost
Few design features have a greater impact on injection mold complexity than undercuts. From a product designer’s perspective, an undercut may appear insignificant: In CAD, these features are often created in seconds. In tooling, however, they can fundamentally change how a mold must be built. A small undercut can introduce: The undercut itself is rarely
The Most Expensive Feature in a Plastic Part Is Often the Assembly
When engineers evaluate manufacturing costs, the discussion often focuses on molding. Questions typically include: These are important questions. However, they often overlook a much larger cost driver. For many products, the most expensive operation does not occur during molding. It occurs after molding. Assembly labor, secondary operations, fastener installation, adhesive application, quality checks, and handling
The Hidden Challenges Behind Multi-Cavity Injection Molds
A multi-cavity mold is an injection mold designed to produce multiple identical parts in a single molding cycle. While multi-cavity molds increase production efficiency, they require careful attention to runner balance, gate design, cooling, and process consistency to ensure uniform part quality across all cavities.
Choosing Mold Textures and Surface Finishes: What Designers Often Overlook
Learn how mold textures and surface finishes affect injection molded parts, including draft angle, ejection, material selection, tooling cost, and cosmetic appearance.
Solving Wall Thickness Problems Before They Become Molding Problems
During DFM reviews, wall thickness is one of the first things we evaluate. It is also one of the areas where we find the most preventable design issues. Many plastic parts look perfectly reasonable in CAD. The geometry may satisfy functional requirements, fit within the assembly, and meet cosmetic expectations. However, once the part moves
Injection Molding Costs Are Determined Long Before Production Begins
Many teams begin discussing injection molding costs after receiving tooling quotations. By that point, most of the important cost decisions have already been made. The geometry has been finalized. The material has been selected. The assembly strategy has been defined. The mold concept is largely determined. In other words, the majority of injection molding costs
