<font size="2"><strong><em><u>Sand Foundy:<br></u></em>Production of models</strong> of several types of timber or epoxide, <strong>production of core boxes, production of cores</strong> of mixture of silica sand and water glass, using the CT method (by carbon dioxide cores hardening), manually or by injecting.<br><strong>Forming technology</strong> - manual shaping under crane, machine moulding or pulse moulding.<br><br><strong><em>In the middle of 2008, desing works were commenced on expansion of the sand foundry. New machine forming workplace will allow foundry to cast even bulk castings (1000x1000x300/300mm, up to 100kg). The expansion will be completed in IV.Q.2008.</em></strong></font>

<font size="2"><strong><em><u>Die Foundry:</u></em></strong><br><strong>Moulds production</strong> - preparation of drawing documentation by our designer team, the production of moulds in cooperation.<br><strong>Casting technology</strong> - <em>gravitational</em> (casting machines CGU and CGH, separate hydraulic-controlled stands, weight of castings 1-20kg), <em>low-pressure</em> (casting machines CNS 10.23, wieght of castings 1-40kg).</font>

<font size="2"><strong><em><u>Machining shop:</u></em></strong><br>Construction and production of tooling in own toolshed. Machinning - mainly aluminium castings, but also alloy and steel.</font>

<font size="2">When the casting is cast, such operation as <strong>trimming, grinding and shot blasting</strong> are performed and, if the customer requests so, also additional operations, such as <strong>heat treatment, machining, impregnation, varnishing and semi-assemblies</strong>.</font>
