Design engineers commonly ask me, “How strong will my staked joint be?” Usually, they are designing a plastic assembly that needs to be staked, and they need to know how to design the part so that it will be strong enough for their application. They are looking for a straightforward answer, like 450 N. If they know how strong one stake point will be, they can plan how many stake points they need and where to locate them. The good news is that we can estimate the answer…
Come visit us in booth 1823 at the Assembly Show in Rosemont, IL this year. Show dates are October 25-27, 2016. We will be performing live demonstrations of hot-plate welding, spin welding, infrared staking, and infrared welding. We hope to see you there!
This question has been posed to me by many customers. I hear statements like, “The machine works great for a long time, and then we suddenly get all of this sticking and stringing.” This issue is somewhat common in most types of staking technologies and varies in severity among different thermoplastic materials.
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.
In large part, the success of a company depends on how quickly and effectively it identifies and solves problems. Any individual or any company can excel if there aren’t problems, but unfortunately no one operates in a blissful land of rainbows and butterflies where problems don’t exist. Do you or your company have the skills to clearly identify and quickly deal with problems?
Join us in Franklin, TN at the SPE Plastics Decorating & Assembly Topical Conference on June 5-7. Extol’s own Bill Reed will be speaking about plastic staking methods. You won’t want to miss it. We will also have a booth at the conference so you can stop by and ask us any questions that you have.
We feel like we are just getting started and we want to hear from you about the topics that we are discussing. We have a lot of ideas for what to write about next, but we thought we'd ask for your input. Here are a few of our ideas: Why is hole size so important for...
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.
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…
