Why Machine Your Plastic Parts?

CNC Machining of parts is the best manufacturing choice when low to medium volume of plastic components is required. The process from idea to manufacturing can be very quick with the use of CNC Machining. Compared to injection molding, closer tolerances are possible and there is no long lead time to produce molds or tooling. Shorter lead times with machining means greater design flexibility, easily adjust components on successive orders. Benefits of Machining: Closer Toleranc

Effective Selection and Design Techniques

When it comes to designing plastic components, questions must be asked and addressed in order to effectively select materials and design techniques for the selected materials. Let us begin to dive into this discussion and effective ideas to consider. Step 1. Determine Whether the Component is a: Bearing and Wear Application (Frictional Forces) or Structural (Static or Dynamic) Application: Determine the primary function of the component, this will direct you to a group of pla

Plastic is NOT Metal

"Plastic is not metal" this will be the talk for today, the first lesson fabricators will discover when attempting to machine plastic for the first time. Plastics and metals both are technically "machine-able," those similarities will end there. Many metals are typically pure materials, plastics are however a blend or hybrid of different compounds. Metals typically hold their shape and have predictable melting points; plastics can expand five (5) or more times their original

Why Consider Using Plastics for Your Part?

In this modern time Engineered Plastics are, wear resistant, flexible and have low coefficients of friction. Engineers for the past decades have been easily replacing metals with plastics. Some reasons for this switch to plastics vary from application to application, are friction, noise, a reduction in weight, longer part life and less maintenance requirements. This leads to significant cost savings for end users and OEM (Equipment Manufactures). Scheduled maintenance for lub
