TiHo LPDC Machines for Aluminum Casting

Low Pressure Die Casting (LPDC) requires controlled filling, stable molten aluminum supply, and consistent process conditions. The right machine configuration can help manufacturers produce high-quality aluminum castings while maintaining efficient production.

TiHo LPDC Machines provide different furnace and casting configurations to meet a range of aluminum casting requirements. The product range includes single-chamber, dual-chamber, multi-chamber, crucible furnace, and super-large single-chamber LPDC machines.

A Range of LPDC Machine Configurations

Different casting applications require different molten metal supply and machine configurations.

TiHo provides:

• Single Chamber Furnace LPDC Machines
• Dual Chamber Furnace LPDC Machines
• Multi-Chamber Furnace LPDC Machines
• Crucible Furnace LPDC Machines
• Super Large Single Chamber Holding Furnace LPDC Machines

This range allows the LPDC system to match different mold sizes, casting requirements, furnace capacities, and production needs.

Controlled LPDC Filling

TiHo LPDC machines use PID control for high-pressure filling. Depending on the machine configuration, filling control can use either a proportional valve or a digital valve block.

This provides controlled filling conditions during the casting cycle and supports consistent process operation.

Flexible Molten Metal Supply

The furnace configuration varies across the TiHo LPDC range.

For example, the standard single-chamber models provide holding furnace capacities of 800 kg and 1,300 kg, with 1–3 optional riser tubes.

Larger single-chamber configurations offer 1,500 kg and 3,000 kg capacities with 11–12 optional riser tubes.

For larger applications, the super-large single-chamber platform provides holding furnace capacities of 2,000 kg, 3,300 kg, 3,600 kg, and 4,000 kg, with up to 20 optional riser tubes.

The crucible furnace configuration provides a 2,800 kg holding furnace and supports 1–10 optional riser tubes.

Dual and Multi-Chamber LPDC

TiHo also offers LPDC machines with dual and multi-chamber furnace systems.

The dual-chamber models use separate pressurized and stewing chambers, with configurations supporting up to eight optional riser tubes. The system also supports continuous production, with a stated production increase of 15–20% for the listed configuration.

The multi-chamber configuration uses two pressurized chambers and one stewing chamber. The system is designed to support continuous casting while maintaining the aluminum liquid at 700°C ±1°C in the stewing chamber.

Mold Cooling and Machine Control

TiHo LPDC machines offer flexible mold cooling configurations.

Depending on the machine, cooling options include:

• Glass flowmeters
• Digital flowmeters
• Digital flowmeters with proportional valve control
• Up to 96 cooling circuits
• Components from SMC, KEYENCE, IFM, and Bürkert

The hydraulic system uses a servo hydraulic drive with a Parker servo vane pump and PHASE servo motor on the listed LPDC configurations.

The electrical system uses Siemens S7-1500 PLC and HMI.

Automation Options

Automation capabilities vary according to the machine configuration.

Selected TiHo LPDC machines support features such as:

• Fully automatic production cycles
• Automatic robot operation
• Automatic filter screen loading
• Automatic part removal
• Automatic mold changeover
• Variable riser tube configurations

Some configurations also use an accumulator to maintain pressure and increase filling speed while reducing power consumption.

LPDC Solutions for Different Production Requirements

Choosing an LPDC machine depends on several factors, including:

• Casting size and weight
• Mold dimensions
• Required production volume
• Holding furnace capacity
• Number of riser tubes
• Mold cooling requirements
• Required automation level

For this reason, TiHo provides different LPDC configurations rather than relying on a single machine design.

TiHo LPDC Machines for Aluminum Foundries

TiHo’s LPDC range combines controlled low-pressure filling, molten aluminum management, mold cooling, hydraulic control, and automation options in different machine configurations.

From standard single-chamber machines to super-large LPDC systems with up to 4,000 kg holding furnace capacity, the range provides options for different aluminum casting requirements.
