Requirements for stamped and deep-drawn parts
After stamping and deep-drawing, drawing greases, oils and particles adhere to the parts. They have to be removed reliably before further processing — usually in larger quantities and in step with the cycle.
The choice of stamping and drawing oil already affects later cleaning: together with ZET-Chemie, we find the oil that secures the forming process and is then easy to remove. For the cleaning itself, we use the high-pressure cleaning systems from RL Automation; when parts are stamped directly from the strip and have to be cleaned immediately, Ossberger’s Single-Piece-Flow is suitable — each part is cleaned individually, right after stamping.
Suitable processes
Which process fits best depends on the part, the contamination and the batch size — we advise on a technology-neutral basis. For this industry, the following are particularly relevant:
- Wet-chemical cleaning — aqueous or solvent-based cleaning, targeted at drawing greases and oils
- Vibration cleaning — cleaning and deburring by vibration
- High-pressure cleaning — cleaning and deburring with the high-pressure water jet (RL Automation systems)
Test the process at TeSe
Whether a process meets your industry’s requirements on your actual part is shown by a trial: 1–2 hours of testing free of charge. In-depth feasibility studies: CHF 1’200 per day, 50% creditable against a machine purchase.
