Hi, As part of a college project I have come up with a new design for a retractable dog lead. I was wondering what the best hardwearing plastic for the outer casing would be. I think it would have to be able to be injection moulded. Would ABS be suitable or is there other more suitable materials available.
Would the same plastic be suitable for small cogs within the lead casing. The teeth may have to take a bit of abuse.

Any input is greatly appreciated. Thanks in advance.
