Annealing/Post-Curing

These heat treatment processes take place after molding with temperatures and hold times depending on the materials used and their thickness. Manufacturing processes can cause internal tension in semi-finished products. At Ensinger, we typically anneal to reduce this stress and increase the crystallinity structure. Annealing improves the strength and chemical resistance of the component and increases dimensional stability over a wide temperature range.

Intermediate annealing is often required for materials that undergo extensive machining to ensure tight tolerances can be met without warping the product.

Ultrasonic Welding

This is another method of attaching thermoplastic components. It uses high-frequency waves to cause intermolecular and surface tension that generates heat and melts the plastic. Once the parts cool, a permanent bond is formed. Like heat staking, this method requires no adhesives or hardware to form the attachment.

Heat Staking

This process is used to attach two components when at least one is a thermoplastic. Controlled localized heat and pressure are used to reform a plastic peg, stud, or boss after it has been inserted into a hole in the other component. When the plastic cools, a bond is created that doesn’t require additional hardware. The controlled nature of this advanced manufacturing service creates almost no mechanical stress on the thermoplastic.

Assembly Services and Packaging

Ensinger provides ready-to-install complete assemblies for many industries. We ensure assembly-specific tolerances of the components are considered during the manufacturing process so your finished product functions as intended. We can then package it according to your specifications.

Some advanced manufacturing services that may be used for assembly include machining, ultrasonic welding, heat staking, hardware placement, laser marking or printing, functional testing, quality inspection, and more.
