Hot Runner Technology - Examples of Hot Runners in Use

|
Synventive Molding Solutions has assembled a collection of practical hot runner examples to help injection molders better understand the technology and how it is applied. The guide presents applications ranging from very small parts (1 g) in multi-cavity molds, to large parts in single-cavity or stack molds. The sample of applications include parts molded from various materials including long glass fiber material.
The guide presents Key Application Information, Customer Requirements, Solutions, Benefits Achieved, and Schematics so molders will be able to quickly reference and relate the applications to their own operations.

PEEK Replaces Costly Metals

|
With the recent start-up of Solvay’s 500 ton/year world-class production unit, Solvay Advanced Polymers now delivers KetaSpire® PEEK and AvaSpire® modified PEEK – two ultra polymers that can give design engineers best-in-class chemical resistance, retention of mechanical properties up to 300°C, plus ease of processing.
KetaSpire PEEK meets the global need for lighter, stronger and better performing alternatives to metals and ceramics. Design engineers can specify PEEK for use in automotive, oil & gas, healthcare, aerospace, semiconductor and various industrial friction and wear components.
KetaSpire and AvaSpire resins are part of Solvay’s complete family of Spire® Ultra Polymers.

A Lesson on Pressure Losses and Differential Shrinkage

|
Focused Training Modules from A. Routsis Associates are complimentary tools you can use to train your workforce. Each module is extracted from one of their interactive training programs. You can play these videos on your computer for a group presentation or provide them to your individual employees.
This lesson is intended to explain how pressure losses within the mold cavity can result in differential shrinkage in the final molded part.

The Plastics Marketplace™
Attention Molders!
How do you know you're getting the best prices from your regrind or excess inventory? Why not place a listing for them in The Plastics Marketplace™? It allows you to quickly and easily list the resin items you want to sell at your asking price. An injection molder recently sold 60,000 pounds of ABS regrind within days. Best of all, it doesn't cost you anything to list your materials. Please contact Mike Kmetz directly to list your materials today!
