Portfolio
Our focus is on the highly productive aluminum machining in the field of CNC milling and turning in batches 100-10000 piece

Just in Time for the assembly
We manufacture components with the highest productivity in the shortest possible lead time. Selected Kuden and we can deliver in 24 hours clock in extreme cases, with a batch size of one piece.

To realize this has been for years closed strategic partnerships. This requires a close and open cooperation is necessary. Of these components, we produce a daily average of about 1,000 parts 1,600 different variants.

Complex requirements
In these complex components, a high accuracy and a highly productive machining is required.

Film and photo optics
Tolerances in the micron range, as well as the form and position tolerances within 0.01 mm require high demands on man and machine.
A sensitive area here is the finishing of the surfaces. Years of experience, modern machinery equipment and technical know-how are crucial for a consistently high quality. We deliver directly to the assembly line.

Since 1988 we have been a recognized workshop for mentally handicapped people who, due to the type and severity of their disability, cannot be employed on the general labor market, or can no longer or not yet be employed again.

In our metal processing we have the possibility to produce turned and milled parts on modern CNC lathes and the 3-axis machining center. In addition, we can offer cuts on vertical circular saws and band saws.
In addition to metal processing, we have several assembly and packaging groups at our site where parts can be assembled and packaged.

compensatory levy

According to the Social Security Code (SGB) IX § 71, every company with at least 20 employees is obliged to employ severely disabled people. The employment rate is 5%, so that for every 20 employees, one severely disabled person has to be hired. If this percentage is not reached, a monthly compensatory fee must be paid.

An order placed with the St. Josefs-Werkstätten Plaidt helps you to minimize these costs or save them entirely, since you can offset 50% of the work included in our invoice amount against the compensatory levy to be paid.

The respective amount is shown separately on the invoice and can therefore be used immediately as a certificate for the integration office.

With our extensive expertise and many years of experience, we offer you professional solutions in the areas of CNC turning, CNC milling and welding as well as tailor-made mechanical engineering and construction.
