Our technical consultants have years of experience working in the foundry and dental industries and can offer you the best advice on how you can add value to what you do.
Our expanding product portfolio has helped us remain at the forefront of today’s foundry industry.
It’s our approach and technical solutions that really set us apart. We don’t stop at meeting your material requirements, we have developed problem-solving products that can help you deliver the best results.
The latest addition to our product-solving portfolio is Geopol, an inorganic binder that can reclaim up to 90 per cent of sand, significantly reducing the environmental impact when producing moulds and cores. It forms an amorphous inorganic polymer exhibiting higher strengths at lower addition levels, compared to the sodium silicate process which forms a colloidal silica gel. If you want to see how Geopol works? Watch the video we created with Northern Stainless here.
Sodium Silicate Binders
John Winter is the only remaining foundry supplier to produce a range of proprietary sodium silicate sand binders in the UK.
Suitable for mould and core making, selection of the right binder system for casting production is possible whether for CO₂ gas or organic ester curing. This is a low gas producing type of binder and is especially suited to gas sensitive alloys (eg: Gunmetal).
Sigmaset 8000 Series No-Bake Binder: This is a low odour aliphatic polyol no-bake system for aluminium applications for mould and core production.
Corovit Oil: Corovit oil is a cold setting sand binder for the manufacturer of cores. It has the same general field of applications as cold set resins except that in most applications the cores are ovendried.
Oil Bonded Sand
As the only producer of oil bonded moulding sand in the UK, John Winter Co. Ltd offers a range of fine oil bonded sands which are used to create a superior casting finish. There are three brands available - Bentomix, Petrobond and Mansbond each with their own distinct properties.
Our product range also includes releasing agents, sand additives and die coatings.
The majority of the John Winter technical sales team have foundry backgrounds, which means our customers benefit from expert advice and consultation every step of the way.
John Winter has nationwide coverage in the supply of dental laboratory materials.
As well as supplying our own products, we are also the official distributors for Shera GmbH, a manufacturer of high quality die stones, investments and other laboratory consumables.
