Staking is ideal for assembling plastic parts. It's quick and inexpensive. It can join dissimilar materials. It eliminates the cost of fasteners and adhesives, and it allows engineers to loosen the tolerances for molded parts.
Not every technological advancement in automotive assembly gets adequate recognition. Consider, for example, how much has been written about the use of aluminum in the redesigned 2019 Dodge RAM 1500 and 2500 trucks, vs. that of ultrasonic welding.
For the past few months, countless manufacturers worldwide have retooled to make personal protective equipment (PPE) for healthcare workers and first responders in their battle against the COVID-19 pandemic. Here are some of their stories.
There's nothing better than starting an ultrasonic plastic welding application and finding the process "window" right away - the sweet spot in which people, parts, equipment and processes run smoothly, with great yields and timely, efficient production.
Matchmaking is a unique skill, and in the world of assembly, few people do it better than equipment suppliers. Day after day, these experts use their extensive experience and knowledge to exactly match the right machine to a specific assembly application.
One of the best things that you can do, both for the design of your product and the success of your business, is to make design choices that keep your assembly options open.

Two of the most popular methods for assembling plastic parts into finished products are adhesives and ultrasonic welding. But how can a manufacturer differentiate between these two options? What questions should product design and manufacturing teams ask when deciding why and when to select these assembly methods?
How well an assembled plastic part performs depends a great deal upon how its component pieces are joined. Those made of strong, hard plastic may be fastened together or bonded. Thermoplastic pieces allow for even more options, including screws and rivets, various types of adhesives or welding, staking and being snap-fit.
Additive manufacturing is no longer just for prototyping. More and more, the technology is being used to make production-ready parts. That's forcing engineers to begin thinking about joint designs and assembly processes.
