Overview Core Making Processes

Organic Processes 

Organic Process
Cold Box

The molding material and the two-component binder are cured at ambient temperatures by means of amine gassing. The after-treatment of the amingase has a decisive influence on the efficiency of the process.

Organic Process
Hot Box

Curing the molding material / quartz sand by heated core boxes while feeding the temperature at about 350 to 400 degrees Celsius and the appropriate removal of the core gases by means of core marks or slot nozzles.

Organic Process
Croning

Croning is a masking process. The hardening of the resin-sand mixture in the molding material takes place by means of heat supply.

 

Inorganic Processes 

Inorganic binder

Inorganic binder systems are usually based on the use of 2 components. The binder and a promoter together enable the sand core to harden. The desired sand core properties can be positively influenced by means of additives based on the required properties.

 

Inorganic process
Cordis by Hüttenes Albertus

The “Cordis” binder from Hüttenes-Albertus is a two-component binder with a highly reduced emission output. The sensitivity to humidity and other properties can be positively influenced by the addition of additives.

 

Inorganic process
Sodium Silicate

The binder is cured in the molding material by gassing with CO2 and can be improved with additives such as esters or other chemicals.

New patented process

Our newly patented process allows a reduction of cycle times of up to 33% with unchanged use of existing inorganic binder mixtures. This is achieved by a complete different approach of core shooting systems and the appropriately adapted core box materials. All further advantages with the use of inorganic binders remain.

 

Overview of advantages versus current
core making processes

 

  • Shorter cycle times up to 33%
  • Uniform curing of every part of the sand cores
  • Higher flexural strength
  • Lower energy consumption
  • Use of existing binder mixtures
  • No post curing required
  • Larger sand core thickness can be achieved (>40mm)
  • Lower wear on the core boxes
  • Higher equipment availability due to less downtime
  • Cost-effective conversion of existing plants

Sand core making in foundries

 

The global foundry industry is constantly changing. Technology improvement in the foundry industry enable better products for consumers and companies.

 The constantly growing economic and sustainability requirements ensure a constant focus on the improvement of existing foundry processes. This focus on foundry industry also requires improvement in sand core making for the various casting processes.

Experts

Foundries are nowadays successful due to their expertise and especially due to strong networking across partners in the foundry industry. Suppliers and customers become partners and contribute to effective production of complex moulding products.

The right choice of machine manufacturers, binder suppliers, sand producers and core box builders is the basis for further future-proof developments of existing casting solutions.
