GROUTING OF FASTENERS, STUD WELDING

Several areas of the modern industry extremely thin and light component parts, such at sheet metals, printed circuit boards or plastic workpieces are used. These have to be fastened securely and permanently, together with ensuring high anti-unscrewing and –unplugging values.

The PEM^® groutable fasteners are widely used from the field of electronics and the automotive industry to the production of machines and devices, airplanes and spaceships. These fasteners do provide permanent and safe fastening in each case. The PEM^® groutable fasteners provide high performance, are easy to install and save time and expenses.

ADVANTAGES

• Extreme load capacity even in the case of smaller and thinner sheet metals
• The special preparation of the mounting holes is not required
• Repeated threading is not necessary
• It is ideal even for coated surfaces
• High placement precision
• Time- and cost-economical

With our PEMSERTER® Series 4 press the following fasteners can be grouted on a high quality level:

Machinable materials:

• Carbon-steels
• Corrosion- and acid-resistant materials
• Aluminium materials
• Plastics
• The maximal distance of the fastener from the edge of the plain component part: 450 mm
• The thickness of the thinnest machinable sheet: 0.8 mm
• In the case of groutable studs: in sizes M2.5-M6, up to a sheet metal thickness of 35 mm, L=6-8-10-12-15
• In the case of groutable spacers: in sizes M3-M5, up to a sheet metal thickness of L=3-25 mm

In the case of groutable nuts: in sizes M2-M10

 

FASTENER STUD WELDING

The SOYER^® PS-9 stud welding pistol with the related SOYER^® BMS-9 power supply represents the most up-to-date stud welding technology. As opposed to the traditional bolt staples, in the case of the new type of collet it is not necessary to set loose studs one by one and to adjust the bolt staple to the studs of different length (6-40 mm). This is the very first time it becomes possible for the operator to recognise all important operating conditions at once with the help of the LED on the pistol displaying the colours of a traffic light. This hugely facilitates the work of the operator and significantly increases the quality of weldings.

ADVANTAGES

• Mobility, can be applied even in the case of large component parts
• No mounting hole needed
• High placement precision
• No burn mark or deformation appears on the backside of even the thinnest welding surfaces not even if the backside is covered with plastic, foil or has received electrolytic surface treatment
• No ceramic ring or shielding gas is required

With our SOYER^® BMS-9 stud welding machine the following fasteners can be welded in on a high quality level:

Machinable materials:

• Carbon-steels
• Corrosion- and acid-resistant materials
• Aluminium materials
• Copper materials
• The thickness of the thinnest machinable sheet: 1 mm
• In the case of groutable studs: studs with sizes M3-M8, and Ø 2-8 mm and a length of 6-35 mm
• Positioning preciseness: ±0.5 mm

Welding speed: Max. 20 studs/minute, depending on the size
