Casting machines
Our machines consist of the machine frame, manipulators, furnace, blackwash bath and electric control. To fulfil the different capacity requirements, a full range of machines with one or two manipulators and one or two riser tubes can be supplied. A choice of freely programmable controls is available: Beckhoff, Allen Bradley, Siemens or Mitsubishi. No foundation or platform is required for the setting up of the machine.
LPDC 0012 (Semi automatic machine)
Semi-automatic operated machine by moving the dies manually and filling of the die by modern, fully computerised low pressure die casting technology.

This machine stands out for its automatical casting process by low pressure technology combined with manual die manipulation To reach the maximum capacity, up to four operators with up to four identical or different dies can work simultaneous.
The working principle of the machine:
- Manual setting of die with cores on the manipulator. Swivelling over onto the furnace and automatical casting
- Remove die from the manipulator, opening it to remove the casting
- Cleaning, cooling and coating of die in a blackwash bath
- Core setting and moving die back to the manipulator
The manipulation of the dies remains manual.
Manual furnace charging with solid material.
Charging of liquid material is possible.

Manual or automatic furnace charging with solid material.
Charging of liquid material is possible.
LPDC 1221
LPDC 2021
Fully automatic machine with rotary portal, two manipulators and one furnace
- Cycle time approx. 42 sec.
- Capacity per shift (8 hours) approx. 550 castings
This machine stands out for a high production rate and the possibility of using two different dies at the same casting temperature.
The working principle of the machine:
- Manual setting of the cores for both manipulators at the same place
- Automatic casting with computer controlled pressure-time curve
- Automatic unloading of the casting
- Cooling and coating in a blackwash bath
The furnace has a melting capacity of 500 kg per hour.
Manual or automatic furnace charging with solid material.
Charging of liquid material is possible.
LPDC 2021
LPDC 2121
Fully automatic machine with rotary portal, two manipulators and one furnace.
- Cycle time approx. 37 sec.
- Capacity per shift (8 hours) approx. 630 castings
This machine is an "upgraded" design of the LPDC 2021 and stands out for its two independent drive units for each manipulator. During the stop of one of the two manipulators for cleaning or die charging, the second manipulator continues its work.
The working principle of the machine:
- Manual setting of the cores for both manipulators at the same place
- Automatic casting with computer controlled pressure-time curve
- Automatic unloading of the casting
- Cooling and coating in a blackwash bath
The furnace has a melting capacity of 500 kg per hour.
Manual or automatic furnace charging with solid material.
Charging of liquid material is possible.
LPDC 2121
Casting machine components
Control
Control cabinet with freely programmable PC control of the machine by Beckhoff industrial PC and touch screen for machine operation, alternatively Siemens S7, Mitsubishi or Allen Bradley. The pressure build-up can be individually programmed and memorized. The casting speed depends on pressure and is programmed and regulated according to the geometry of the castings. On the touch screen error messages as well as important production data are shown.
Manipulator
The new manipulator stands out for a new guiding system with heavy duty roller rail system. The manipulator movements are actuated by hydraulic cylinders. The die closing stroke is 10 kN. Maximal die dimension 500x400 mm
Blackwash bath
Temperature controlled cooling/blackwash bath of stainless steel with two separate baths and agitators.
Workpiece removal
Automatic casting removal ejecting from die and dropping on a stainless steel sliding table. The sliding table moves the castings to the backside of the machine. As an alternative to the removal table a gripper on a robot for accurate positioning can be offered.
Die cleaning
The cleaning unit consists of two shot blasting stations, each for one half of the die.
Core shooting machines
Cores must satisfy all kinds of requirements, such as resistance, limitation of gas evolution during the casting process as well as a simple, clean removal of cores after casting. The quality of the sand, the chemicals and their mixture is very important. We supply two different versions of core shooting machines for casting of faucets.
LK01
Automatic core shooting machine for hot-box cores. Manual core removal after ejection directly from the core box or the cross slide.
Technical data:
- Shooting head volume 3 liters
- Core box dimensions 400x300 mm
LK02
Automatic core shooting machine for hot-box cores. Core removal from the conveyor belt. It is possible for one person to operate two machines.
Technical data:
- Shooting head volume 3 liters
- Core box dimensions 400x300 mm
