Vision inspection & sorting machines for O-ring and rubber part makers.
Rubber parts fail quietly — a flash line or a small cut that no sampling plan catches becomes a field leak. Visimaster machines flip and inspect both sides of every seal, at speeds a manual inspection line cannot touch.

What O-ring defects can the machines catch?
The published inspection list for O-rings covers Dirt Mark, Flow Mark, ID Dent, ID Cut, OD Dent, Bend, Flash, Cut Mark, Peel Off & Short Mould — with both sides of every ring inspected. The exact list for your seal is confirmed on a real machine run in the free feasibility check.
How fast can O-rings be inspected?
Inspection speeds run up to 300 PPM on the Glass Disc platform, and the dedicated O-ring configuration is published at up to 600 PPM. The exact speed for your ring size is confirmed in the feasibility report.
How do I check if my O-rings can be inspected?
Courier 50–100 sample parts — including a few defective pieces — to our lab in Bhosari, Pune. Our engineers run them on the actual machine platform and you receive a feasibility report, typically within a week. The check is free. Prefer to start online? Upload a drawing or photo on the Ask AI page and get an engineering answer in minutes.
Will it work on your exact part?
Describe your part to Visi, our AI sales engineer — or courier 50–100 sample parts (including a few defective pieces) to our Bhosari lab for a free feasibility study.
