Casting & Forging

Casting & Forging

Casting and Forging have a long tradition at JST, and can be traced back directly to the origins of the company over 10 years ago. Since then, the range of processes has increased enormously so that today's manufacturing processes include

These developments were accompanied by a huge increase in the materials available. Today, many markets are supplied with foundry and forged products made from approximately 700 different alloys. Companies from the automobile industry, air and space travel, ship and machine construction, electrical engineering and energy generation are among the list of customers. JST is a leading expert in many different manufacturing processes, we could supply the OEM service for all of these kind parts with competitive price and total solutions.

Investment casting is a precision casting method which is growing steadily in international significance for reason of economy. The method is being used to produce larger and larger castings. Investment casting is also employed on an increasing scale for so-called super alloys which require ever more complex smelting processes.


Die casting is a versatile process for producing engineered metal parts by forcing molten metal under high pressure into reusable steel molds. These molds, called dies, can be designed to produce complex shapes with a high degree of accuracy and repeatability. Parts can be sharply defined, with smooth or textured surfaces, and are suitable for a wide variety of attractive and serviceable finishes.


Our team of Machine Operators, Process Control Technicians, and Quality Personnel all work together to ensure our casting machine output meets or exceeds industry standards and customer specifications. We also perform a variety of secondary operations such as sanding, milling, drilling, tapping and assembly; as well as working with several top notch commercial painters.
