Our rotational moulding step by step

Rotational Moulding Step 1

Mixing the LDPE powder

We use LDPE powder (low density polyethylene) as base material for rotational moulding which is dyed in your desired colour.
Rotational Moulding Step 2

Filling the mould

The ready-made powder is filled into the mould and closed after that.
Rotational Moulding Step 3

Heating & Rotation

The filled mould now gets heated to 260° C slowly melting the LDPE powder will spread evenly by rotary motion.
Rotational Moulding Step 4

Final product

After the rotational moulding is completed the cooled down, final product is removed and ready for final assembly.


By rotational moulding we are able to manufacture all parts forming a hollow body (less weight). Custom requests can be processed as well since the needed moulds are designed and built by us. The finished products are almost stress-free and comparatively immune to pressure or collision. The use of LDPE powder leads to sturdy and chemically resistant product.

Parts we manufacture by rotational moulding are for example toilet fronts, toilet tanks, hand wash stations, urinals and plastic pallets. To gain more insight have a look at our adjacent gallery or just come to see us at our facilities. We are looking forward to your visit.

Our vacuum forming step by step

Vacuum Forming Step 1

Heating of the sheet

First, we put a sheet of HDPE (high density polyethylene) in desired colour into the thermoforming machine heating it up to 120° C.
Vacuum Forming Step 2

Formed by vacuum

The now fixed and heated sheet is draped over a mould and stretched to the specific shape using a vacuum.
Vacuum Forming Step 3

Cool down & remove

The stretched plastic part is cooled down into shape and removed by overpressure.
Vacuum Forming Step 4


In a final step the product is trimmed into its final shape and ready for assembly.


Vacuum forming is a cost-efficient way to produce large scaled plastic parts out of HDPE (high density polyethylene). Because of HDPE’s great sturdiness and tensile strength parts can be produced with very low wall thickness making it resistant to acids, bases and other chemicals like cleansing agents.

We use vacuum forming for side panels and roofs of our portable toilets as you can see in the adjacent image gallery.


Most of the needed parts for our production are manufactured at our metalworking shop. This way, we are independent from external lead times in large parts, able to find solutions when needed promptly as well as realizing custom projects.

Here we build the moulds we use for rotational moulding, small components needed in the construction department and base frames for houseboats. The development and construction of assembling aids for various production purposes belongs here as well.

In addition, our metalworking shop focuses on stair construction for the GLOBALINER series as well as manufacturing custom-made Pick Up units.


For more than 15 years we engineer and assemble chassis mounted vacuum service units according to your custom requirements here at our own construction department.

Furthermore we design and build the chassis for the GLOBALINER series, transport trailers in different sizes and box bodies for various use cases.
