You can still solve part issues after you build a tool

There are three major elements in thermoplastic design. Each is an opportunity to improve production efficiency, end-product performance and quality. The first opportunity is part design, with material selection being a close second and mold design third. Optimizing the three plastic part design inputs – part design, material and mold design – are the best … Continue Reading

Thermoplastic Part Improvements using a Foaming Agent

Thermoplastics have a lot of good attributes, but they aren’t perfect.  Thicker ribs or walls will show sink marks.  Surfaces can show the signs of minor impacts or scuffs.   Larger parts with thicker sections require longer cycle times to ensure there is no part deflection upon mold opening.  When part designs result in molding … Continue Reading

Comparison of Off Shore Tooling vs Domestic Tooling

Hi-Tech Mold & Tool, Inc. has our own tool room, so we quote tools that we make.  When our customers request it, we’ll work with off shore tooling vendors but Offshore Tool Quotes and Domestic Tool quotes are not the same.  Below we’ll outline some differences that we’ve experienced over many years of building and … Continue Reading

Functional Thermoplastics

The aspect of thermoplastics that I’ve always thought is the most interesting is the ability to make thermoplastics more functional.  Most thermoplastic applications that are older than 10 to 15 years are applications that utilize thermoplastics as a shell or protective package.  Old and new desk telephones use thermoplastic as the shell, as do most … Continue Reading

PEEK2PEEK: Carbon Fiber filled PEEK bonded together

  Hi-Tech has been bonding Carbon Fiber filled PEEK parts together for over 10 years. We decided to bond two scrap pieces of Carbon Fiber filled PEEK together and run a test to see the largest mold we could lift before the bond failed. Comment if you were surprised.

Why are my plastic parts cracking?

Plastic parts can crack or fail for a variety of reasons.  The part could be deformed beyond the mechanical properties of the material causing yield or break issues.  Breakage can be characterized by brittle and and  ductile mechanical failure.  Brittle will typically show a sharp break and ductile will stretch and tear which may include … Continue Reading

Injection Molding 101: Machine Clamp Tonnage

  This is the second of two videos about the basics of Injection Molding.  This video reviews the Machine Clamping mechanism.   Our equipment list shows the various injection molding machines at Hi-Tech and they are generally refered to as a 100 ton press or a 500 ton press.  This refers to the clamping pressure … Continue Reading

Injection Molding 101: The Injection Unit

  This is the first of two videos built around teaching about Injection Molding machines.  The first video focuses on the Injection Unit.   Our equipment list contains both the Ounces of Polystyrene that each Injection Molding machines Injection Unit or barrel will hold and the Peak Injection Pressure.  The Ounces of Polystyrene is most … Continue Reading

Berkshire Black Iron

Hi-Tech first started manufacturing Aerospace components and assemblies in 1994.  The interesting thing about this Aerospace work is that it wasn’t the traditional trim pieces or covers for the cockpit or fuselage.  All of the components and assemblies that Hi-Tech manufacture go into the belly of the airplane and most have significant mechanical requirements. Based … Continue Reading
