Industrial Resin

Three-part phenolic resign system like Cold Box Resin or Pep-Set Resin, are also made by Indo-Bell, for special castings.

Shell-Molding Resin:
This is a phenolic novolac type resin in liquid stage. Shell  moulding process is a two part system. The first part is the resin where as second part is the catalyst, in powder form. Coated sand made out of Shell Moulding resin, provides good cold and hot tensile strengths, proper stick point and minimum peel-back.

Normally 1.8 to 2.5% resin on sand is sufficient for the cores, but sometimes 3 to 4% resin on sand is required for the production of moulds which are subject to higher stress during casting, than cores.

In the shell moulding process resin coated sand is placed into a heated metal pattern (250 - 280°C) by means of a dump-box or blowing with special machines into hot closed moulds.

For making resin-coated sands, for use in the shell-moulding process, Indo-Bell manufactures Phenol-Formaldehyde resins, both in liquid and powder forms. Indo-Bell also manufactures suitable ‘Shell-Catalyst’ for the liquid Phenol-Formaldehyde resin for the shell-moulding process.

Notes:
Advantage of Shell-Moulding Process—the process distinguishes itself by a very accurate reproduction of all the contours of the model, very narrow tolerance can be maintained during the casting operation and is of particular importance to the automotive industries because of its high tolerances in comparison to other process.

Hot-Box Resin:
A wet resin and sand is blown into the heated core box. Indo-Bell manufactures Furfuryl Alcohol modified Hot box resin with lower nitrogen content. The hot-box process is applicable to mass production of small and medium volume castings, in the automotive industries.

This is a special type of phenolic no-bake resin with two part system, used for the large size Iron and Steel casting for the machines and automotive industries.The first part is the resin where as the second part is the catalyst in liquid form.

The Alfa Set resin have some added advantages over the conventional no bake binder – such as: a) Comparatively cheaper, b) free from distressful fume emission, c) Smooth surface finish, d) Suitable for almost all Indian sand e) No effect of humidity on the moulded cores f) The resin contaminated tools are easily washable with plain water only g) easily collapsible cores.

We are the manufacturer, supplier & expoprter of different types of Nodulated Rockwool. Loose bulk Rockwool converted through stages of slicing separation of foreign particles more so called the shot content and then seiveng to eleminate the dust silica content result nodulated fibres. These fibres without any loss of its insulating value finds application in auto brake pads, railway brake blocks and many other applications of fiction industry.

The standard packing is in PP Bags of 12.5 & 20kgs.

• Zircote S 56 spirit based Zircon Coating ready to use backed by superior covering and suspension properties It is most suitable for use on green sand, CO₂ set and resin bonded sand moulds/ cores, and for casting all metals, also including critical jobs in steel and heavy cast iron foundries.

 

• IBI Zircote S 56 is also effective in nickel based composition and light alloys in green sand resin bonded and sodium silicate moulds.                                                                                                                      

      Purpose:

• In the process of high temperature alloys as steel, cast iron, non ferrous etc it becomes imperative to coat the sand surface before it comes into contact with molten metal to prevent sand wash of course sand erosion, metal / mould reaction metal penetration, sand burn – on / fusion.

 

• IBI Zircote  S 56  has been designed to withstand very high temperature of molten metal also acting as a barrier between the molten metal and core or maybe a mould surface, thereby preventing sand burn on metal wash erosion, metal/ mould reaction and many other defects when casting high temperature alloys
