4 spin welding tips to think about

Spin welding is a really good method for joining thermoplastics. It’s easy to understand, the tooling is simple, the strength results are impressive, and the process is really robust. Keeping those results consistent and managing weld flash control can be a challenge, however.
Here are a few things to think about and watch out for as you consider implementing spin welding.


The Aspirozzle required spin welding on both ends of a main body. Cycle time requirements necessitated two simultaneous welds. To accomplish this, two Vortex PRECEDENCE spin welder actuators were mounted horizontally in a custom machine.

How to solve problems until you find a land flowing with milk and honey

An outpouring of God’s love

This past spring break, I had the opportunity to travel with six fellow Extol employees, their spouses/children, and a group of people from Kentwood Community Church to serve with Back2Back Ministries in Cancun, Mexico. With the goal of helping families stay together, Back2Back provides holistic care in the areas of physical, spiritual, educational, emotional, and social needs. We were blessed to be able to help in many of these areas in our time there.

Hide those unsightly gaps

Staking stretchy cloth material can be challenging. In the initial design of this gap hider, the bosses were very tall and parallel to each other which created some difficult staking angles at either end of the bracket. Extol recommended…

March Madness and welding

Ultrasonic welding vs. Hot-plate welding. When you picked your March Madness teams, you considered strength of schedule and how their weaknesses matched up. Let’s talk about welding plastic parts for life science applications and how weld strength and leak (weakness) compare between ultrasonic welding (USW) and hot-plate welding (HPW).

4 common mistakes people make when hot-plate welding

In our last blog post, we discussed that you only need 2 things to weld plastic, heat and pressure. It really is that simple. However, there are 4 common mistakes that people often make when setting up a hot-plate weld that can prevent adequate heat and pressure from being achieved. Today we’re going to explore these mistakes and how a strong weld can be attained by avoiding them.

You only need these 2 things to weld plastic

Believe it or not, you only need two things to weld plastic parts together. Heat and pressure. Just look at hot-plate welding as an example. For those of you who may be unfamiliar with the hot-plate welding process, it goes like this: Two parts are…
