Injection Molding Defects: Causes, Prevention, and Fixes.
Common Injection Molding Defects and How to Prevent Them in the Design Phase Most injection molding defects are not manufacturing problems. They are design problems that manufacturing cannot solve. Sink marks, warpage, short shots, and weld lines all have root causes in the part geometry, and the correct fix is a design change, not a […]
Rapid Prototyping in Atlanta, GA | RPM Fast
Rapid Prototyping in Atlanta: How RPM Fast Serves US Engineering Teams Atlanta is home to a significant concentration of product development activity: automotive suppliers, medical device companies, defense contractors, consumer product startups, and industrial equipment manufacturers. Teams at these companies need rapid prototyping and low-volume manufacturing partners that are close enough to visit, fast enough […]
Silicone vs. EPDM vs. Neoprene: Choosing the Right Rubber
Silicone vs. EPDM vs. Neoprene: Choosing the Right Rubber for Your Part Silicone, EPDM, and neoprene are three of the most commonly specified elastomers in custom rubber parts work. They share some applications and are frequently substituted for each other, often incorrectly. Each has a distinct performance envelope, and choosing outside that envelope produces premature […]
How to Write an RFQ for Prototype Parts (With Template)
How to Write an RFQ for Prototype Parts (With Template) A manufacturing RFQ is the document that determines how quickly and accurately a supplier can quote your job. A complete, well-structured RFQ produces a fast, accurate, bindable quote. An incomplete one produces a back-and-forth clarification process that adds days and often results in pricing qualifications […]
5-Axis CNC Machining: When Do You Actually Need It?
5-Axis CNC Machining: When Do You Actually Need It? 5-axis CNC machining is one of the most frequently misunderstood capabilities in precision manufacturing. Some engineers assume it is always necessary for complex parts. Others avoid specifying it because they assume it is significantly more expensive. Both assumptions lead to the wrong process for the job. […]
How to Reduce Lead Time in Custom Parts Manufacturing
How to Reduce Lead Time in Custom Parts Manufacturing Lead time in custom parts manufacturing is not a fixed variable. It is the sum of every delay between order placement and part delivery, and most of those delays are controllable. Purchasing managers and engineering teams that understand where time is lost can often cut total […]
Wall Thickness Guidelines for Injection Molded Parts
Wall Thickness Guidelines for Injection Molded Parts Wall thickness is the single most influential geometric parameter in injection mold design. It determines how plastic flows through the mold, how the part cools, where shrinkage occurs, and whether the finished part will be dimensionally stable. Most of the defects that appear on injection molded parts : […]
Urethane Casting vs. Injection Molding: Cost and Speed
Urethane Casting vs. Injection Molding: Cost, Speed, and Quality Compared Urethane casting and injection molding both produce plastic-like parts. They share some applications, appear in the same stage of product development, and are frequently compared when a team needs 10 to 500 parts and is deciding which process to use. The decision turns on volume, […]
Laser Cutting Tolerances and Design Rules for Designers.
Laser Cutting Tolerances and Material Limits: What Designers Should Know Laser cutting looks precise in CAD. In practice, kerf width consumes material, heat changes edge geometry, and tolerance compounds across nested parts. Designers who understand what the process can hold avoid the most common surprises between DXF submission and finished parts. This guide covers achievable […]
ISO 9001 in Manufacturing: Why Certification Matters
ISO 9001 in Manufacturing: Why Certification Matters for Prototyping When a purchasing manager or procurement team is qualifying a new manufacturing supplier, ISO 9001:2015 certification is one of the most commonly requested credentials. It is also one of the most frequently misunderstood. Certification does not mean every part will be perfect. It means the supplier […]
