Machining of technical plastics – custom production

We offer machining of technical plastics and production of custom parts according to requirements. It commonly performs all operations such as drilling, milling, turning, grinding and more.
We perform machining on conventional machine tools as well as on CNC machining centres.
Depending on the situation, we use waterjet cutting, injection moulding and other technologies.

We perform both piece production (production is possible from 1 piece) and large-scale production using automated production processes.

Successful plastic machining requires certain specific technological processes. Compared to steel or other machined materials, plastics are not as dimensionally stable and are more susceptible to temperature changes. Different types of engineering plastics also behave differently when machined. We base our machining not only on these specific requirements, but also on our many years of experience in machining engineering plastics.

Other plastic materials and products

In addition to these industrial plastics, we also offer other types of plastic materials and products:

Full polycarbonate

Transparent thermoplastic with excellent mechanical properties with double-sided UV filter. Used in many applications where it successfully replaces glass.

PVC strips

Plastic is mostly used as a filling of slatted screens or swinging doors. However, there are no limits to the imagination. We offer several types of PVC foils in up to 17 colour variants.

Standard foils

Standard transparent film with UV filter and flame resistance most commonly used for screens, The material is highly tensile, cold resistant and is chemically stable. On the surface there is a special layer increasing the abrasion resistance of the material, thickness 0.3 to 10mm, width 100 – 2200mm.

Kalt foils

PVC film for temperatures down to -40°C with UV filter for cold storage and freezer rooms, thickness 1 to 4mm, width 100 to 400mm.

Antistatic foils

Antistatic films are designed for clean environments. They offer high transient and surface resistance with UV filter. Available in thicknesses from 1.5 to 3mm, widths from 150 to 300mm.

Reinforced foil

These “ribbed” films are approximately 30% more impact and wear resistant than conventional films due to the longitudinal ribs. The main use is for slatted screens with a high frequency of passage of transport equipment

Weld foils

The special films are mainly intended for engineering and industrial environments. The radiations produced by various welding processes are harmful to vision, especially the ultraviolet, blue and infrared spectrum. For optimum protection, it is not only sufficient to protect the welders, but also the surrounding area.

Technical information

The material, which belongs to engineering plastics, is highly tensile, cold-resistant and chemically stable. A special layer is sealed on its surface to increase the abrasion resistance of the material.

  • 1300×7 mm

Plastic with reinforcing mesh, welding slats and ANY size of plastic up to a maximum width of 2200 mm are delivered on request. The manufacturer’s condition is the purchase of the entire plastic bale (20 or 50 bm).

Laminated screens

Strip curtains made of softened PVC serve as draught-proof curtains or plastic partitioning of the space, curtains and partitioning reduce heat loss in winter, reduce leakage of e.g. cold from freezer boxes. They prevent the ingress of dust into buildings, can reduce noise levels, and secondarily can serve as an additional source of daylight.

The screens can be used up to a height of 5-6 m depending on the situation. It is important to oversize the screens according to the thickness of the plastic and the percentage of overlap of the individual strips.

Types of slatted screens

Standard slatted screens

Produced in transparent slats 200/2, 300/3 and 400/4 mm (width / material thickness). For use from -35°C to +60°C except in freezers.

Freezer slat curtains

It is made of 200/2 and 300/3 mm slats. They are used from +5°C to -45°C in freezers. It is inappropriate to install this type of plastic in areas with higher temperatures or continuous sunlight.

Non-standard slatted screens

  1. Welding box screens made of dark plastic with UV filter to prevent penetration of ultraviolet rays
  2. Outdoor openings of baths, swimming pools, showers, saunas
  3. Separation of spaces in warehouses, pavilions, production halls, cooling and freezing boxes, machine fencing
  4. Atypical:
    • Side-scrolling shutters
    • Screens on auxiliary structure
    • Colour screens
    • Atypical use, according to customer requirements

Swing gates

The plastic filling made of transparent soft PVC is fixed in a single or double leaf steel frame construction. This is fitted with industrial spring-loaded closers that return the sash to the closed position after passing through or over from both directions.

Swinging doors serve mainly as an effective draught excluder, to separate areas with different climates, to separate operations with different hygiene requirements. They prevent heat from escaping from heated areas and are an essential addition to the entrances to cooling and freezing boxes. A great advantage is the simple handling during operation, when the opening of the wings is done by pushing or bumping into the plastic filling, closing is automatic immediately after the passage. Compared to various quick-action systems, swing gates are significantly cheaper and easier to maintain. Compared to slatted screens, the big plus here is the much more comfortable passage of equipment and people.

Technical information

Door construction

The steel construction of the door leaf is standardly made of AISI 304 stainless steel profiles, which are suitable for use in both normal operations and in the food industry or in areas that are extremely exposed to corrosion. According to the customer’s requirements, we also offer a hot-dip galvanized version.

Design for lighter operation

Gates are used for smaller openings (up to approx. 2×2 m), where passages of people or other people prevail. manual handling trolleys. The filler plastic is made of clear softened PVC, thickness. 5 mm, on request it can also be 7 mm thick. For anchoring into the floor and ceiling, NPT closers are used, for anchoring into the side of the opening, spring-loaded German Hawgood closers are used.

Designed for heavier traffic

Preferably in holes max. 3×3 m, where, in addition to the passage of people, electric and motorised handling trolleys and other machinery pass through the gates, where there is a high frequency of passage. Technical plastics of transparent thickness of 7 mm are used, optionally. plastics with a reinforcing grid. As a swinging system, German or NPT stainless steel spring closers are used, with greater durability and the possibility of adjusting the spring preload. On request, each door can be equipped with a locking system, whereby a leaf opened by more than 90° is locked in the open position. For freezer plants, we offer a swing door variant with a special plastic infill that retains its properties down to -35°C.

Technical plastics

PTFE Teflon

Polytetrafluoroethylene (PTFE) is a polymer with very high chemical resistance, excellent high temperature resistance (resistance to -200°C and +260°C), excellent sliding properties, almost zero water absorption and high resistance to ageing. Due to these properties, Teflon is used in the most demanding applications and environments where other polymers cannot be used. PTFE has excellent chemical resistance, resisting acids, alkalis, salts and solvents. The material is available in the form of rods, sheets/boards and tubes.

It is available in several variants: pure PTFE (virgin) – Teflon without added impurities. PTFE filled with graphite – Teflon filled with 15% graphite. The added graphite improves the sliding properties of the material. The material also has better thermal conductivity. However, you have reduced chemical resistance due to the addition of graphite. PTFE filled with glass – Teflon filled with 25% glass. The addition of glass particles increases the resistance to pressure, solidify and increases wear resistance. The addition of glass therefore increases the mechanical properties of the material. It is also dimensionally more stable at high temperatures than pure Teflon. However, when filled with glass, the material becomes thermally and electrically conductive and its chemical resistance to alkalis and acids is reduced. PTFE filled with carbon – Teflon filled with 25% carbon. The added carbon increases the material’s hardness, creep resistance and also resistance to wear due to friction. The carbon filling increases the thermal and electrical conductivity and reduces the temperature of the material. This makes it suitable for the production of precision parts. It has reduced chemical resistance. It is resistant to hydrofluoric acid. For less demanding applications, PTFE recyclate can also be supplied, which is more affordable. Further information on PTFE can be found for example here
