Elliot molding and tool

Engineers will typically hunt for a magic bullet and, when they find it, assume that it will solve all their future problems. In injection molding, shear has a far more significant impact on the flow behavior of a material than the temperature of the barrel.

Higher shear generally means lower viscosity. So, consider your screw design, your injection velocity and the diameter of your flow channels. If you are not already using simulation, it can be a hugely valuable tool because it avoids the need to iterate on the press. Instead, you get to understand the impact of different variables at the click of a button.

Elliott's Pneumatic Hammer is the recommended tool for removing tube stubs in heat exchangers or beading tubes in firetube boilers.

They will provide time and tool savings compared to commonly available lubricants. With a wide variety of rolling motors on the market, choosing the right one can seem overwhelming. There are several factors to consider when selecting a rolling motor. Power source, torque control, RPM, [ There are two motor power sources that are used for expanding tubes mechanically: electric rolling motors and pneumatic rolling motors.

Determining what motor to use for a job will depend on operator preference, availability of electricity or air, and the application. Tube Expanding is based on engineering principles, involving elasticity and plasticity, to compress the OD of the tube against a fixed container, such as rolling tubes into tube sheets, drums, ferrules or flanges.

To assure a proper tube joint, the tube wall must be reduced by a predetermined percentage. Then sign up to receive our monthly newsletters!
