J. T. Price is Westley Group's Sand Casting Centre of Excellence and is based in Newcastle-Under-Lyme, Stoke on Trent. J. T. Price is a market leader in the supply of raw, proof and finish machined sand castings, with sizes ranging from a few kgs up to approximately 7000 kgs.

Castings are manufactured for commercial and critical application in an extensive range of copper-based, nickel-based and aluminium alloys. J. T. Price is also particularly well-known for bronze sculpture and architectural castings. 

Total Casting & Machining Service

Westleys are market leaders in the complete supply of high-integrity copper and nickel-based sand castings, specifically those requiring the stringent testing demanded for naval & defence applications.

We produce high-integrity castings up to 7 tonnes in weight with complete NDT, machining, assembly and certification available as required.

Engineered Products

Bespoke and high-integrity sand casting components, architectural and engineering solutions, and semi-automated volume manufacturing.

J. T. Price is one of the World’s premier suppliers of complex sand cast components for engineering and architectural applications. We supply castings from a few kgs in weight up to 7 tonnes in all copper-based, nickel-based  and aluminium alloys. Our standard lead times are short and our bespoke service accommodates very small batch size requirements. Extensive testing, machining and assembly are routinely provided.

Art & Architectural Products

J. T. Price produces sand cast art and architectural products, façade panels, curtain walls and ancilliary pieces from a few grams to very large in scale and weight.

Our highly skilled workforce and unique processes have enabled us to work with world renowned artists and architects , installation and envelope specialists across the world for more than 20 years.

A range of specially developed proprietorial techniques enable us to manufacture castings of significant size, whilst retaining highly-defined finishes and maintaining incredibly thin sections (5mm). Benefits for large scale projects include maximised speed of production and costs that can be more readily controlled.

One of our key specialties is the production of thin section and highly defined cast panels for use in large scale façade and curtain wall projects. We continue to be involved in highly prestigious building projects, where we work very closely with the architect on both aesthetic design and structural compatibility. We supply all copper based materials but often produce projects in various aluminium, special iron or steel alloys.

Semi-Automatic Moulding Carousel

As part of a £1M investment project to provide a Sand Casting Centre of Excellence for our customers at Westley Group’s Stoke facility, a semi-automatic moulding carousel and core-blowing platform was installed at J. T. Price in September 2013.

Commissioned from foundry equipment supplier Omega, the state of the art equipment has been strategically designed to create a highly-resourced platform for the long-term supply of copper and nickel based sand castings up to approximately 60 kgs. For Francis W. Birkett customers, the investment secures the provision of high-quality sand castings to support FWB’s precision machining and assembly facilities in Cleckheaton.

Impellers

Impeller production at J. T. Price requires extensive skill and experience due to intricate core assemblies and thin section vanes interacting with thicker section shrouds.

Impellers drive fluid through a pump body and are critical to the hydraulic performance and longevity of a pump casing. Impellers are subjected to various forms of corrosion depending on the environmental media they have been chosen to perform within. JTP produce impellers in all heat, wear and corrosion resistant alloys including aluminium bronze AB2-CC333G, copper tin alloys such as CT1, leaded gunmetal, Monel and stainless steels including dupex.

Impeller sizes range from 15cm to 2.5 metres in diameter. Impellers can be fully machined in our own machine shop if required.

Valves

The valve industry is one of our major market sectors and as such we cast various copper-based, nickel-based and steel parts for butterfly, check and ball valves up to 7 tonnes in weight.

J. T. Price manufacture many different types of valves including Globes, Gates, Swing Checks, Angle, Flowcheck, SDNR, Non-return, Wafer and Ball Float. Valve Bodies include ‘Y’ Strainers and mud boxes which stop dirt getting into motors and pumps. Sizes range from ½” to 72” and JTP can supply the full range of castings in all heat, wear and corrosion resistant alloys.

If supplied finish machined, items can be pressure tested and fully certified. Certification ranges from 3.1 certification through to DPI, 3.2 witnessed and up to 100% radiography. Parts are certified as per the relevant material specification with additional customer requirements if required.

Marine Components

In conjunction with Westleys, J. T. Price has an extensive record in the supply of NES 747 PART 2 and PART 4 nickel aluminium bronze castings to many of the world’s navies.

Our speciality in this field has been the supply of corrosion resistant and pressure containing items for high-integrity, safety critical applications. Our castings are routinely 100% radiographed, heat treated, dye penetrant tested and witnessed as required. Our success in this field has led to us becoming UK MOD and Babcock approved, as well as supplying regularly into the USA naval program.

Marine components can be supplied in the proof or finish machined condition, or as cast if you require. Machining is managed in our in-house machine shop. Westley Group actively manages the complex logistics process associated with the certification and delivery of complete ship sets of fittings. Over recent years the responsive and flexible requirement to supply spares in the quickest possible manner has been our strong point.

We supply marine components such as propeller hubs and associated CPP components in a full range of sizes, up to 6 tonnes in weight. We also supply propeller blades up to 2000 kg in weight.

Bearing Components

J. T. Price produce bearing components for the offshore and marine industry for a wide range of heavy and light applications such as steel works and power stations.

Bearing components are often specified in copper-based alloys due to the material properties providing inherent lubricity whilst maintaining heat and corrosion resistance. Bearings can be produced in leaded bronze, phosphor bronze, gunmetal and other heat, wear and corrosion resistant alloys.

Body Scanners

J. T. Price have been producing the internal parts for MRI scanners (Magnetic Resonance Imaging) in sand / centrifugal castings for over 30 years.

The aluminium castings are produced to a very high standard in LM27 material with the average weight of the casting being around 700kg.

Seal Components

Seal components can be produced by static casting methods to exacting standards.

Seals are produced for all commercial type vessels and also for stringent military applications across Asian, European and American Navies. Various materials can be produced from a few kilos to many tonnes all in heat, wear and corrosion resistant alloys.

As well as supplying to the shipping industry we also supply to the hydro market sector to the same exacting standards. Parts are generally finish machined in our in-house machine shop prior to despatch.

Commercial Sand Castings

J. T. Price supplies commercial grade sand castings to companies in the UK and abroad in all heat, wear and corrosion resistant alloys.

At JTP, we work with our customers to provide an economical solution to the most technical of projects, never relaxing the highest quality standards that our customers expect.

Our continuous improvement policy means cost savings in the production process can be passed on to the customer. Customers can also take advantage of our quick turn-around of parts where costly down-time can be kept to a minimum.

Customers always have the option of letting J. T. Price manage the entire process from casting to finish machining and assembly.
