Overview

HotFlo! is a process improvement technology for hot chamber Die Casting, which : -

• Improves casting surface quality
• Reduces casting porosity
• Reduces wasted sprue and runner mass
• Lowers Die Cast manufacturing cost

HotFlo! totally eliminates the sprue in hot chamber Die Casting and enables much smaller runners to be used. It provides a fully tapered metal feed path from the machine to the casting, improving the process capability.

The sprue bush and sprue post used in a traditional hot chamber Die Casting die are no longer required. In its place is a Hot Sprue Kit, a set of precision components with an electric heating element, which maintains the alloy above its melting point and provides a smooth, unrestricted metal flow path.

The metal arrives at the gate with greater heat content improving casting surface quality.

The metal pressure losses are reduced, producing castings of better integrity.

The causes of entrapped air in the feed system are eliminated leading to a reduction in casting porosity.

The massive reduction of sprues and runners reduces dross losses, energy use and manufactured cost.

The net result is an increase in quality, a decrease in costs and an increase in customer satisfaction.

Who can benefit?

HotFlo! is suitable for many types of Die Casting companies and applications.

• Contract, jobbing or specialised Die Casting
• In-house, captive or cell based Die Casting
• Die Castings with high quality requirements
• Electroplated, powder coated and painted Die Castings, where every reject is a costly waste
• High volume production
• Horizontal hot chamber machines from 20 to 600 tons.

HotFlo! enables progressive Die Casting companies to gain an edge over their competitors and enhances hot chamber Die Casting in relation to other processes.
