Plastic Annealing

Understanding Plastic Annealing: Process, Benefits, and Best Practices

Knowledge Hub, Assembly, Manufacturing, Manufacturing Defect / By

During plastic molding, the outer surface of a part cools faster than the inner area. This uneven cooling can lock residual stress into the material, affecting dimensional stability and long-term performance. Annealing provides a controlled way to relieve these stresses through carefully managed heating and cooling cycles, allowing the material to reach a more stable […]

Selective Laser Sintering (SLS)

What Is Selective Laser Sintering? A Complete Guide to SLS 3D Printing

Knowledge Hub, 3D Printing / By

“Selective laser sintering” might sound unfamiliar at first, yet the concept becomes clear once you recognize it as a form of 3D printing. SLS builds parts by selectively fusing polymer powder layer by layer, typically without support structures. This makes it well suited for complex geometries, functional prototypes, and low-volume production parts. What Is Selective

soft tooling vs hard tooling

Soft Tooling vs Hard Tooling: Which One Fits Your Production Needs?

Knowledge Hub, Mold / By

In manufacturing, “tooling” refers to the molds, dies, jigs, and fixtures used to shape materials during production. When people think of a “mold,” they often picture hard tooling—but soft tooling also has an important role in manufacturing. This article compares their respective strengths, weaknesses, and ideal applications. Soft Tooling Soft tooling refers to temporary, low-cost

Structural Foam Molding

Structural Foam Molding: How It Works, Benefits, and Applications

Knowledge Hub, Injection Molding / By

Choosing between part weight and structural strength often involves a trade-off. Structural foam molding reduces material density while maintaining the stiffness and strength needed for many larger or thicker plastic parts. This article explains how the process works, where it is most useful, and when it may be a practical choice for your design. What

High-Speed Machining

Understanding High-Speed Machining for Precision CNC Parts

Knowledge Hub, CNC Machining / By

High-speed machining might sound like a casual way of saying “CNC machining, but faster.” In practice, though, it refers to a specific approach — cutting parameters, tooling, and machine dynamics tuned for particular speed ranges. Here’s what actually distinguishes it and where it delivers real value. What Does HSM Stand For? High-speed machining (HSM) is

Types of Steel Materials

Types of Steel Materials: A Complete Guide to Grades and Uses

Knowledge Hub, Material / By

Steel is one of the most widely used metal materials, yet it encompasses a remarkably diverse range of classifications and grades shaped by differences in chemical composition, mechanical properties, and manufacturing processes. These factors influence how each type of steel performs and where it is best applied. This section examines how composition, performance, and intended

Mill-Turn Machining: How It Works and When to Use It

Knowledge Hub, CNC Machining / By

Mill-turn machining sounds exactly like what it is: a combination of milling and turning, and that’s precisely the case. But that simplicity is easy to underestimate. Bringing both processes into a single setup on one machine can change how features are designed, how accurately their relationships are maintained, and how much time and cost go

"Axis" on a CNC Machine

3 Axis vs 4 Axis vs 5 Axis CNC: Which One Do You Need?

Knowledge Hub, CNC Machining / By

Terms like “3-axis” or “5-axis” CNC can sound cryptic at first glance—but they simply describe how many directions a machine can cut from. Yet that simple definition carries real weight: understanding these differences can lead to smarter part design, tighter tolerances, and more informed CNC sourcing decisions.

Mold-Tech Texture Explained: A Complete Guide for Custom Molded Parts

Knowledge Hub, Design Guides / By

Among the various texture standards used in manufacturing, “Mold-Tech” comes up frequently in RFQs and technical drawings, yet many buyers aren’t entirely sure what it refers to or how it differs from other finish callouts. It’s easy to assume this is just another way of saying “textured surface,” but that’s not quite right. In reality,

Rubber Injection Molding

A Guide to Rubber Injection Molding for Custom Parts

Knowledge Hub, Injection Molding / By

Injection molding was originally developed for processing plastics, but advances in rubber processing technology have made it a reliable method for producing rubber components as well. Today, rubber injection molding is widely used for applications that require consistent quality, complex geometries, and efficient production at medium to high volumes. But what makes rubber injection molding
