|MK_mini||This system has been designed for smaller companies, universities and training facilities. Electronics and luxury was deliberately renounced and this way, a solid and very compact machine was created. It is operated manually, which allows a very precise casting even of small quantities. The system is delivered with two heating cabinets and the tool set at an unrivalled favourable price – you can safe the rest.||1400||450x470x400|
|MKV_system_1||With a casting weight of more than 1 kg, System 1 is perfect for most of the classical rapid tooling applications. It can additionally be equipped with a heating cup to manufacture wax cores for metal investment casting.||1400||450x470x400|
|MKV_system_2_eco||Easy installation, operation and maintenance, compact and good value. Mechanical 3-way valve pressure control, electrical mixing and tilting.||6000||850x870x800|
|MKV_system_2||In this chamber, which is basically structured like System 1, components can be manufactured which are twice as large. The whole cup unit can be pulled out for easy charging, mixing and tilting speed are infinitely variable.||6000||850x870x800|
|MKV_system_2_XL||Side door for big parts, extractable mixing unit, separate pre-evacuation chamber, pressure frame for gravitation cast, removable. Differential pressure system and roller conveyor as standard equipment.||6000||2080x1000x1000|
|MKV_system_3||This system contains two systems: two Systems 2, to be precise. Each of these systems can be operated autonomously and independent from the other one in order to mould parts up to the size of a television casing. If the size of one chamber is not big enough, both units can be combined automatically to a big chamber by just one touch of a button. Parts up to a length of 2.5 meters and 10 kg overall weight can be cast in this chamber. The system is charge though the side door.||12000||2680x1000x650|
Differential pressure system
The advantages of the differential pressure system
If required, MK equips all chambers from System 1 upwards with the so-called Differential Pressure System. Compared to pure gravity casting, this process has the following advantages:
- Even very sophisticated, complex, very long and thin moulds can be filled perfectly.
- High-viscosity resins as well as fibre-filled resins can be processed without problems.
- Resins with a very short pot life (up to 2 min.) can be easily cast,
- The sprue can be much smaller, which reduces the time for rework.
Maximum pressure difference: 100 mbar
Development of pressure difference: 10 - 60 sec.
Neutralization of pressure difference: > 1 sec.
Filling time compared to gravitation casting: 1/3
If a vacuum machine is equipped with the differential pressure system, the upper chamber containing the casting and mixing unit is separated from the lower mould chamber by a steel rib. The casting funnel passes through this rib. When the differential pressure system is switched on the upper chamber is flooded to a pre-selected differential pressure up to 100 mbar. As there is still almost a complete vacuum in the lower chamber, the resin is pressed into the mould, accelerated by the differential pressure system.
Application of the heating cup
The practical value of the vacuum chamber can be increased tremendously by applying the heating cup. Now wax patterns can also be made using the same technology and the same silicone moulds. While the investment casting industry continues to grow, there is an ever increasing demand for quality wax patterns.
Temperature: 30° - 120° C
Capacity: 1.3 or 6 ltr.
The advantages of the turning table
- evacuation of several moulds
- turning table to be mounted by a single operation
- height-adjustable by means of a lift
- practical and time-saving
With the aid of the turning table, several moulds can be filled during the evacuation process. The appropriate quantity of resin is filled into the funnel and flows into the mould below. Then the next mould is positioned under the drain by means of a key switch, and filled. Especially resins with a longer pot life are suitable for this process. The turning table can also be mounted later on by a single operation, provided that the system has been ordered with the respective preparation. In connection with the lift, the whole unit can also be adjusted vertically.
