Precision Clamping System:

The advanced design of the four corner lock-up closing system on Profit® Hot Chamber Machines offers several extraordinary features that contribute not only to the quality and consistency of castings, but also to protecting the machine itself from undue wear and damage. The design puts support where it is needed, behind the die, and it also contributes to ease of maintenance. This four-corner design minimizes platen deflection around the die, compared to other toggle systems. All toggle castings are machined on special CNC machines so that toggle parts are interchangeable and there is no need for shims or selection to achieve uniform toggle stack length. Short, large diameter toggle pins are used to prevent pin breakage and minimize bushing pressure. All movement of the traveling plates is supported by hardened steel ways. A crosshead guide with a large bearing area assures straight toggle travel and positive lock-up.

All machines have a motorized die height adjustment mechanism to allow for precise adjustment of various die thicknesses. The ejection systems can be either center hydraulic ejection or hydraulic bumper plate ejection. The hydraulic bumper plate provides a large area for "knockout" rods and can accommodate many different size of dies.

The Profit® Hot Chamber Machine four corner lock-up system, with the unique ability to adjust each corner of the machine individually, provides the accurate repeatable lock-up that is required to produce consistent, high quality castings. The Profit® Hot Chamber Machine four corner toggle design puts support directly behind the die, thus preventing warping of the plates or a "warp-around" effect of plate to die. In addition, the closing system utilizes an economical regenerative hydraulic power system, which requires less motor horsepower and therefore is less expensive to operate.

Compare the Profit® Hot Chamber Machine with any other die casting machine and you will find that the construction, design, operational efficiency, the "teamwork" of the four corner lock-up closing system along with the proven and reliable shot system will convince you that the Profit® Hot Chamber Machine is the finest value on the market today.

Clamping System Comparison:

Clamping System Comparison	Profit® Machine Four Toggle Corner Loaded	Other Machine Two Toggle Horizontal or Vertical
Die Supported Area	Large Supported Area.	Limited Supported Area.
Locking Toggle Type	Four corner lock-up toggle system. Locking load is displaced over large area. Allows for large ejection patterns.	Two horizontal or vertical toggle. Locking load poorly distributed over platens. Platens tend to wrap around dies. Allow large ejection patterns.
Component Replacement	Toggle components machined on special CNC system assures complete interchangeability. Linkage can be disassembled without pulling tie bars.	Shim or parts selection required to match toggle stackup lengths. Tie bars must be pulled to disassemble linkage.
Component Life	Large diameter short toggle pins assure long life and rarely break.	Long toggle pins are susceptible to bending and breakage.
Toggle Lubrication	Special embedded solid lubricants have excellent self-lubricating features and remarkable wear resistance in any severe condition and under high load. Grease once a month, no environmental pollution.	Requires delivery of a constant metered flow of lubricating oil to all moving parts to reduce operational friction and wear, but causes environmental pollution.
Four Corner Adjustment	Possible and simple.	Possible but difficult.
Locking Comparison	Balanced loads - minimizes platen deflection around the die area. Unbalanced loads - tie bar is able to compensate and balance the loads simply.	Unbalanced loads - tie bar unable to compensate.
