Easier to Handle and More Consistent Strength than Alternatives

Owens Woodwork and Fiberglass Manufacturing creates fiberglass structures for a wide array of applications. Several examples would be giant pineapples for an amusement park, large decorative columns for a casino, and very ornate decorative fencing. For these complex designs, the structure must normally be molded in several pieces and adhesively assembled. The adhesive joint could either be a tight fitting joint or a joint made by filling in the large gaps between the pieces. Pix above shows an application with a ½” wide gap. Once bonded, the excess adhesive is removed with a putty knife and the adhesive is allowed to cure. The joint is then manually sanded and the final assembly is painted. The adhesive must provide structural strength, have sufficient open time to be dispensed on large parts, and it must be compatible with sanding and painting.

Start-up Hospital Equipment Manufacturer Saves on Costs and Time

Warana Adaptions – a start-up company in Vic., Australia – is making Hospital Detachable Poles. Warana previously used centre punching to retain cylindrical SS tubes. In this process the customer would insert the mating parts in place and create ‘dents’ on the surfaces with a punch to create friction between the parts. It was a labor intensive and yet not 100% reliable process. Customer also used a 2-k epoxy to act as a shim between the SS tube & plastic insert – it took 24 hrs to cure. Customer was looking for improvements in overall process.

Meets High Torque & Temperature Requirements, Saves Assembly Costs

Pragati Automation, India manufactures Machine Tool accessories. They assembled torque motors for Bio-Directional Tool Turret, where very high torques are induced. During the assembly, the Rotor was heat shrink fit on to the shaft and Stator was heat shrink to housing with high interference. These motors develop temperatures of 120 deg C continuous. Shrink fit of assemblies involves – heating costs and time, additional labor and still lower reliability and customer wanted to improve on these.
