Depends on the material flow properties. For high flow materials like acetal(delrin) you need at least 2-3 tons of clamping per projected sq. inch of all parts runners. For somthing a little more resistant to flow like poly carbonate (lexan) you can easily expect to triple the clamp tonnage requirement. A lot of machines out there for reasonable prices, but don't forget the rigging on both ends and freight, not cheap.
You might be better off contracting time on sombody elses machines or have them shoot parts for you. We offer these services in NW Ohio on our 100 to 400 Ton presses. from $30 per hr. |
