SKB is recognized globally as an industry leader in the design and manufacture of molded polymer transport cases. Vacuum, rotational or injection molded, these cases are engineered to provide protection for equipment utilized by hundreds of companies involved in diverse industries from music and pro-audio products to military, industrial and medical applications. SKB even supplies maximum travel protection for consumer sports and electronics equipment.

The SKB Methods

Injection Mold
This is SKB's latest venture in our 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 of our parts, such as our patented Trigger Latches are produced by the injection mold process. Our 3i case series includes a gasket that makes the case watertight and dust proof. Our latest injection molded cases for guitars and basses are very popular with touring musicians. These cases have dual lives as they are also used for military weapons. Never before has an ATA flight case been so lightweight, yet so advanced.

Roto-Mold
In 1997, SKB invested in rotomold 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
Vacuum Form Also known as thermal form, this was the first and most recognized “SKB Style” case. This method is very popular for everything from guitar and band instrument cases to golf cases, rifle cases, and more. 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 then heated and vacuum formed around aluminum castings, thus taking the shape of the mold. The edges have a 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.
