TPI vs. Die Casting

Energy Efficiency

TPI offers a remarkable reduction in energy consumption of up to 50% compared to conventional cold chamber die-casting. This is achieved through various factors, including significantly lower operating temperatures (approximately 100°C lower), reduced magnesium consumption for product manufacturing (thanks to reduced runner sizes through nozzle technology), and the high dynamic potential of the system, allowing for rapid cylinder cooling over the weekend and a quick restart within 1-2 hours.

IMPROVED WORKER SAFETY

TPI uses only a minimal amount of high-temperature magnesium, approximately 2-3 times the amount of the shot size, as the melt is produced just in time. In contrast, dosing furnaces contain significantly larger quantities of magnesium.

REDUCED MATERIAL CONSUMPTION

The use of nozzles in TPI for the direct introduction of magnesium into the cavities significantly reduces the need for runners to distribute magnesium from the casting channel to the workpiece.

COST OF OWNERSHIP

Extended tool lifespan, longer spare parts life, savings on casting materials, reduced energy consumption, and shortened cycle times are crucial features contributing to cost reduction in TPI production.

ENVIRONMENTAL RESPONSIBILITY

TPI relies solely on electrical energy and avoids the use of protective gases and gas for melting alloys, contributing to a more environmentally friendly manufacturing process.

IMPROVED PRODUCT QUALITY

Semi-liquid casting processes offer a 20% increase in component durability, noticeable through higher elongation and tensile strength due to a finer microstructure and lower porosity.

TPI vs. Thixomolding

Melting performance

To achieve the required melting rate and cycle times for larger products or alloys like AM50, larger diameter and longer screw assemblies can be used. TPI allows for maintaining the needed shot dynamics, as there is no need to accelerate the heavy screw during injection

HOLDING PRESSURE

Thixomolding machines do not offer the ability to build holding pressure from accumulators and multipliers; instead, they exclusively use oil from the hydraulic pump for this purpose.

NO CHECK VALVE

In Thixomolding, the presence of a check valve is crucial to ensure product quality. However, maintaining the check valve is typically labor-intensive and costly. Its function is also dependent on friction factors and dynamics. In TPI, the dosing chamber is sealed from the filling chamber through hydraulic, precisely controllable movements.

MACHINE DYNAMICS

Compared to Thixomolding machines, die-casting machines have a significantly broader performance range (PQ² and nomogram).

AVAILABILITY

The components used in TPI are readily available standard components worldwide, including brands like Siemens, Bosch Rexroth, and SEW.

MATURED MACHINE BASE

TPI machines offer several advantages, including retractable tie bars, compact machine lengths, high closing forces, and the flexibility to cast aluminum when needed.
