Injection Mold
This is SKB’s latest venture in their quest to provide the most innovative hard shell case products. Injection molding is an expensive investment and there is no room for error.
Made with extreme pressure, even the smallest injection molded part requires a very large and heavy mold. SKB has molds that are nearly 20 tons! Many SKB cases such as the patented Trigger Latches are produced by the injection mold process. Many cases include a gasket that makes the case watertight and dust proof.
ROTO-Mold
In 1997, SKB invested in roto-mold machinery. These molds are ideal for making larger cases and cylindrical cases. The PE roto-mold material starts as a fine powder that is measured according to the size of the case. The material is then sealed up in a multi-piece aluminum mold and fixed on a biaxial rotating wheel. The material is heated at 800° in a very large oven while constantly rotating. The powder melts and coats the inside of the mold and after cooling, the cast is disassembled and the case is removed. Roto-Molding is great for providing maximum protection and can withstand maximum impact in transport.
Vacuum form
Also known as thermal form, this was the first and most recognized “SKB Style” case. This method is very popular for guitar or band instrument cases. In 1990, SKB developed the first vacuum formed rack case. Acrylonitrile Butadiene Styrene (ABS) or Polyethylene (PE) is formed into solid sheets of material. The sheets are heated and are vacuum formed around aluminum castings, thus taking the shape of the mold. The edges have the distinctive aluminum valance that provides rigid construction as well as a secure fit. Vacuum formed products are known for their light weight and extreme durability.
