Injection molding of motor housings
Injection molding.

At STIHL we not only manufacture plastic components using conventional injection molding techniques with single and multiple cavity molds, but also with new production methods such as the internal gas pressure or 2-component process. In subsequent production processes, such as tampo printing or vibration welding the parts are processed and then assembled into modules ready for installation.

We rely on a "simultaneous engineering process" to reduce costs and further improve quality and productivity. In other words, the design and production engineers work closely together; production experience flows directly into the development of new products.
Where do you buy the raw materials for your plastics production? We purchase pellets conforming to our specifications exclusively from selected certified manufacturers. You manufacture 75% of the necessary plastic parts yourselves. How many active part numbers do you have to manage? We have about 1200 different active part numbers ranging from the fuel tank case of our biggest chainsaw to the tiniest stopper weighing only 2.4 g. Each part is delivered just-in-time for to the assembly line. How does injection molding actually work? Can you explain it to me? Injection molding is like baking cakes. The material pellets are melted in the machine and injected at high pressure into the mould. Reapplying injection pressure automatically compensates for shrinkage, occurring
during cooling.
How fast can I get spare parts? What is the lead-time STIHL offers for spare parts? STIHL provides a service rate of 97%. In other words, the spare parts needed are almost always available quickly but depending on where you are and where the order is filled.
