In injection molding, small design details often determine whether a part runs efficiently—or creates ongoing production problems. One of the most important of these details is the draft angle. Draft angles are frequently overlooked during part design, yet they directly impact: Part quality Tool life Cycle time Production cost Understanding and applying proper draft angles …

In injection molding, small design decisions can have a major impact on part quality, cost, and manufacturability. One of the most important—and often overlooked—of these decisions is gate design. The gate is where molten plastic enters the injection mold cavity, and its design directly affects: Material flow Part strength Cosmetic appearance Cycle time Defect risk …

When sourcing an injection mold, many OEMs focus on cost, lead time, and piece price. But one of the most important—and often overlooked—factors in plastics manufacturing is the SPI mold classification. These classifications define how a mold is built, how long it will last, and how it will perform over time. Understanding SPI mold classes …

In injection molding, there is one variable that has a greater impact on cost than almost anything else: Cycle time. While many OEMs focus on material costs or tooling investment, the reality is that cycle time is often the single biggest driver of piece price in plastics manufacturing. Understanding how cycle time works—and how to …

For many companies, 3D printing is the perfect place to start. It allows engineers, product developers, and startups to move quickly from concept to physical part without the time and expense of production tooling. It is ideal for prototyping, design validation, and early-stage product development. But there comes a point when 3D printing stops being …

When designing plastic components, many engineers focus on part geometry, material selection, and basic manufacturability. But one of the most overlooked opportunities for cost reduction and performance improvement is this: How the part will be assembled. Design for Assembly (DFA), often combined with Design for Manufacturability (DFM) as DFMA, is a critical discipline in injection …

Automation has become one of the most talked-about trends in injection molding and plastics manufacturing. From robotic part removal to fully automated production cells, many manufacturers are investing heavily in automation with the goal of reducing cost and improving efficiency. But here’s the reality: Automation does not always reduce cost. In some cases, it delivers …

For many OEMs, sourcing plastic components comes down to a critical decision: Should we manufacture domestically or overseas? At first glance, overseas injection molding—particularly in Asia—can appear to offer a lower piece price. But as many companies have learned, piece price is only one part of the equation. When you factor in lead times, quality, …
