Production process

FUNDYSER provides experience and confidence during all its production phases.


Study and simulation

Our tools for this process are:


Highly accurate feeding software that simulates mould filling and solidification phases.


Programme that analyses stresses and deformations during the solidification process.



This phase of the process is carried out with alkaline phenolic resins.

  • Moulding lines to fill boxes from 500 x 500 up to 1000 x 1000 for individual pieces and small series, with an OMEGA Mixer 6 Tn/h.

  • Moulding lines to fill boxes up to 3,000 x 3,000 with ONDARLAN Turbomixer with articulated arm 20 Tn/h and 6-m radius.


Melting and Casting

All the melting machines are equipped with an aspiration unit with a capacity of 10,000 m³/h.

  • Inductotherm 400 kW machine with a 875 kg tank.

  • Inductotherm 350 kW machine with a 1,250 kg tank.

  • Inductotherm 450 kW machine with a 1,800 kg tank.

  • Inductotherm 350 kW machine with a 550 kg tank.

Maximum melting capacity: 4500 kg.



Demoulding with shake out unit and mechanical conveyor belt

  • Demoulding unit with shake out unit and fully streamlined sand attrition unit and with Donaldson aspiration unit with a capacity of 8,000 m³/h for boxes of up to 1250 x 1200.

  • Demoulding machine with mechanical conveyor belt feed to sand attrition shake out unit. Totally streamlined and with a Donaldson aspiration unit with a capacity of 10,000 m³/h for boxes of up to 3500 x 3000.


Shot blasting

This part of the process is conducted with two shot blasting machines:

  • ALJU tunnel shot blasting machine Regina-type Mod. 08 with steel blasting material and grain capacity of 3 Tn, 2,000 mm high, 1,900 mm wide and 2,450 long, equipped with three 7.5 kW turbines for steel parts.

  • Shot blasting machine ALJU Mod 161/I-A 7, stainless steel 1700 mm high, 1350 wide and 1400 long.


Heat  treatment

We have four thermal treatment furnaces with various capacities:

  • 200 kW furnace measuring 2500 X 3500 X 1500

  • 175 kW furnace measuring 1650 x 3000 x 1500.

  • 60 kW furnace measuring 1200 x 1200 x 1250 with water tempering basin.

  • 200 kW furnace measuring 2550 x 3500 x 1500.
