Product development
Product development for castors, wheels and pressed steel parts
From idea to series part
70 years of forming
Castor and wheel parts since 1954.
Prototype in weeks
First parts from our own toolroom and lab.
One plant
Pressing, welding, moulding, plating and assembly on one site.
Engineer to engineer
Your engineers talk directly to ours about drawing and tolerance.
Standard products and custom parts
Our five product groups
Our product groups often include bearings and rotating parts, with tight tolerances and low friction.
- Castors for waste containers and industry
- Castor wheels
- Wheelbarrows
- Steel rims with or without pneumatic or solid rubber tyres
- Stamped and deep-drawn OE parts
If your part can be pressed, deep-drawn, welded, moulded or plated on our machines, we can develop it, also when it has nothing to do with castors.
Development process
Six steps from idea to series production
Every new product, standard or custom, goes through the same six steps.
Step 1
Requirements
We start with the application, the load, the quantities, the timeline and how you want delivery and service to work. Both sides sign off on what the part has to do before design starts.
Step 2
Concept and CAD
Our engineers model the part in CAD. For an existing part we start from a 3D scan, so the model matches the real dimensions.
Step 3
Cost and material
FEM analysis and test runs show where material can come out without losing strength. Less material means lower cost and a smaller carbon footprint.
Step 4
Prototype and test
We build functional prototypes and test them for strength and durability, and the coating in our salt spray chamber.
Step 5
Refinement
We correct what the tests show and freeze the design. Wishes for a later version are recorded, so the next development starts faster.
Step 6
Series production
Tools, trial series and series production in Postojna, under our ISO 9001 quality system.
What our development changes for you
Function
A part that works for the person who uses it, such as a brake pedal that needs less force.
Material
Less steel or plastic for the same strength, checked with FEM before tooling.
Lifespan
Zinc of 10 to 15 µm or powder up to 100 µm on parts that would otherwise rust.
Cost
Less material and fewer process steps lower the cost of the part.
Transport
Production in Slovenia, close to the ports of Koper and Trieste, with recycled material where it holds the load.
What we make in house
Stamping, deep drawing, welding, injection moulding, zinc plating, powder coating and assembly happen in our own plant in Postojna. Laser-cut blanks, CNC machining and hot-dip galvanising come from partners, so one order from us still covers the whole part.
- Stamping and forming
- Injection moulding
- Zinc plating
- Powder coating
- Assembly
- Trimming and edge forming
Processes
The processes we use to develop and produce your part.
- Classic stamping and forming
- Transfer and servo pressing
- Deep drawing
- Circumferential and manual welding
- Thermoplastic injection moulding (PA, PP, PU, PE, TPE)
- 2K injection moulding
- Automatic and manual assembly
- Zinc electroplating and passivation
- Powder coating
- Trimming, rolling and curling
Industries we develop for
We develop custom parts for the industries below.
Quality and certificates
Quality management to ISO 9001 since 1995, environmental management to ISO 14001 since 2000.
Our waste container castors are SKZ certified to EN 840-5 and RAL-GZ 951/1.
Environment
1.41 MWp of solar on our roof, Cr6+-free zinc plating, 100 % recycled rubber treads and PP wheel centres.
95 % of our coating powder is reused, and all wastewater from plating is treated in house.
Why OEMs work with us
One plant
Pressing, welding, moulding, plating, coating and assembly on one site in Postojna.
Certified quality
Quality management to ISO 9001 and environmental management to ISO 14001, with inspection at each production step.
Prototype to series in weeks
Short lines between design, toolmaking and production let us move from a first idea to series parts in weeks.
Engineers who speak to engineers
Your engineers talk directly to ours about drawing, tolerance and process.
Cost per part
Each process is planned to save time, energy and material on your order.
70 years of pressing
We have formed steel for castors, wheels and rims since 1954.
