 Jigs vs Fixtures: An Overview

Jigs and fixtures are frequently utilized in CNC machining to ensure precision, accuracy, and quality of CNC machined components. These are both types of engineered tooling designed to hold things in place during machining. The ability to hold things in place makes jigs and fixtures workholders for CNC machining. While both of these terms are […]

How to Build a BOM

Chefs create recipes. Hardware Engineers create BOMs (Bill of Materials) and SOPs (Standard Operating Procedures). The BOM is an ingredient list for building your product, and the SOP is the set of instructions on how to build it. In this article, we’ll explain how to construct an excellent ingredients list that will help you clearly […]

Specialty Plastics and Polymer Blends for Injection Molding

Specialty plastics for injection molding have material and performance properties that meet the requirements of more demanding applications. These include engineering plastics and resins for medical, automotive, aerospace, electronics, and other applications. Polymer blends — mixtures of two or more polymers that form new materials with different properties — are also used to meet tougher […]

Product Study: Gate Sizes and Placement in Injection Molding

The Challenge: Avoid Gate-Related Part Defects Injection molding gates are larger or smaller in order to support the direction and volume of flow into the mold cavity. If a gate is too large, molten plastic may fill the cavity unevenly and cause part defects such as weld lines and shrinkage. If a gate is too […]

3D Printed Light Pipes: Overview and Material Selection

The advent of 3D printable transparent materials has opened doors to new possibilities with rapid prototyping for optical applications. Now, we can consider how to use and manipulate light with 3D printed parts. Light pipes, sometimes referred to as light guides or light tubes, are physical components used to purposefully redirect or transport light from […]

Tapped Holes vs. Threaded Holes – Dispelling the Confusion

When designing mechanical assemblies, it’s likely that they’ll require fasteners for assembly. Fasteners like screws and bolts are commonly used to secure mating components, and they usually require some type of hole for assembly. There are many types of holes to use to install fasteners such as countersunk, counterbore, tapped, tapered, spot faced, and screw […]

Top Five Guidelines for Selecting a Plastic Injection Molding Manufacturer

What’s the best way to choose a plastic injection molding manufacturer? What criteria do you need to consider, and how can you tell if a molder is the right partner for you? According to Plastics News, there are nearly 600 injection molders in North America alone. Researching all of them would be incredibly time-consuming, but […]

Hard Metals vs. Soft Metals for CNC Machining

The mechanical hardness of a material is defined as the ability of it to resist deformation. Hardness is measured by the amount of indentation made by a standardized applied force to the surface of a material.  Hardness is an important characteristic to consider when designing components that interact with each other. For example, when designing […]

Enclosure Design 101 for Injection Molding and 3D Printing

The power of an electronic or mechanical product usually comes from its internal components, but those products are recognizable because of their plastic enclosures. Those outer shells protect the components inside and make the entire system appealing and user-friendly. In this article, we’ll walk you through the steps of designing a prototype plastic enclosure for […]
