Features

• Low maintenance due to few moving parts, heavy duty, rugged, and dependable.
• Center line ram pressure.
• Twin cushioned tilt cylinders provide a smooth tilting motion from start to stop.
• Twin ram cylinders provide a safety factor, as well as extra holding pressure and better clamping balance.
• Hydraulic power units available in manual, automatic, or with programmable controllers, sized to facilitate all available accessories at low operating pressure.

Options

1. Front Ejector
2. Powered or Manual Swing in Casting Catcher

These precision machined leader pin bushings are specifically designed to be used with Stahl leader pins. Made from high grade meehanite iron, they will provide fast and accurate alignment between the two mold halves. With the use of a retaining nut and specially designed shoulder they can be easily replaced as mold wear dictates, there-by providing consistent alignment throughout the life of a mold.

With internal diameters from .500" to 1.000" these bushings can be used in the construction of both small and large permanent molds. Each bushing comes with one jam nut.

Please refer to the Typical Permanent Mold Assembly sheet and individual catalogue sheets fro all your mold component requirements.

Oversize mold mount plates should be used when additional mold mounting surface is needed above or below standard mount plates. (See separate catalogue sheets for Standard Mold Mount Plates).

Mold mount plates are fully machined and ground on all surfaces from carbon steel plate.

Please refer to the Typical Permanent Mold Assembly sheet and individual catalogue sheets for all your permanent mold component requirements.

power units are designed to operate each of our Permanent Mold Casting Machines with optional accessories in manual or automatic mode. Timing for pouring and cooling are controlled for repeat production without variance. The hydraulic pump is variable volume/pressure compensated, and coupled directly to the TEFC electric motor. Standard configuration is with 4 adjustable timed functions and 4 valves to control tilt and ram, as well as core pulls and / or ejectors. Our automatic control unit is a PLC controlled system which offers easy repair for any maintenance crew. The reservoir is fitted with an air cooled aftercooler and system includes a separate recirculating pump to reduce heat build up and maintain reasonable system temperatures under severe service conditions. This adds significantly to the pump life and reduces down time. We incorporate the latest and most innovative designs to increase your production and profits by reducing your labor.

• Low maintenance due to few moving parts, heavy duty, rugged, and dependable.
• Unique design allows the mold to be poured while the parting line is perpendicular to the floor. The Machine tilts the mold so that the parting line is parallel to the floor for solidification and ejection.
• Cushioned tilt cylinder provides a smooth tilting motion from start to stop.
• Twin ram cylinders provide a safety factor, as well as extra holding pressure and better clamping balance.
• Integral lower eject is included.

CMH Manufacturing Co. introduced a new twist on the reverse tilt process at the CastExpo. Our static cylinder head machine inspired the development of the HALL RT2H. The machine has twin opposing rams and a lower cylinder that can be programmed as a pull or an ejector. The ram cylinders each have 15 stroke and the distance between the platens when both rams are open is 42 and with both rams closed the distance is 12. The maximum clamping force is 29, 000 pounds. The stroke on the pull/eject is 4 with pulling force of 16, 200 pounds and pushing force of 18, 500 pounds. It is available with standard or proportional tilt.

• Low maintenance due to heavy duty dependable design.
• Hydraulic mold clamping.
• Vacuum assisted venting.
• Can be set up as double side pull or quad side pull.
• Bottom ejection cylinder.
