Zinc Die Casting and Assembly: 5 Essential Benefits

Our zinc die casting and assembly service helps you source finished products from one manufacturing partner. Buying a casting is often only one stage in getting your product ready for sale or installation. Machining, surface finishing, bought-in components, assembly and protective packaging may all need coordinating before the order is complete.

For manufacturers and product businesses, those extra stages mean more supplier conversations, more deliveries and more opportunities for a detail to be missed. Jones & Wilkinson brings zinc diecasting, in-house toolmaking, secondary operations and assembly together, helping customers source finished products through one manufacturing partner.

Based in Willenhall in the West Midlands, we work with customers who need more than a loose casting. Our in-house assembly service complements our casting capability, with locally sourced components and finishing services supporting the complete product.

1. Zinc die casting and assembly with one point of contact

A component can meet its drawing and still need several operations before it is useful to your business. A housing may need tapped holes and a protective finish. A decorative product may require polished and plated castings, springs, plastic mouldings and careful packaging.

When those stages are purchased separately, your team has to coordinate the interfaces. Who checks the finish before assembly? Who maintains stock of the bought-in parts? Who makes sure the completed product is packed appropriately for despatch?

Our assembly team works with customers on these practical requirements. Combining zinc die casting and assembly gives you a clearer route from casting to completed product, with fewer separate handovers to organise. The exact scope is agreed around your product and order requirements.

2. Casting, machining and assembly planned together

Decisions made at the start of a project affect the cost and practicality of everything that follows. In-house toolmaking and tool maintenance allow us to consider the die alongside the later manufacturing stages, rather than treating it as an isolated purchase.

Our secondary operations include tapping, drilling, barrelling, auto-shot blasting and CNC machining. This gives us flexibility when a casting needs additional features before it can be assembled.

For components with lower annual quantities, a simpler tool followed by CNC machining can sometimes be more economical than incorporating every feature into the die. We can compare the production options and advise on a suitable approach for your quantities and component design.

Planning zinc die casting and assembly together helps you assess the complete manufacturing cost, including the work required after casting, rather than comparing the casting price alone.

3. Bought-in components and finishes coordinated for your product

A finished assembly may combine zinc castings with plastic mouldings, springs, turned parts or pressings. Jones & Wilkinson sources these bought-in components locally and has established relationships with regular suppliers.

We also coordinate a range of finishes, including powder coating, passivation, barrel nickel, and polishing and chrome plating. Our assembly team monitors the quality of painted or plated finishes as part of its work with customers.

For you, the benefit is a manufacturing partner that considers how the casting, additional components and finish come together. Whether appearance, fit or the intended operating environment is your priority, discussing the complete product early helps establish what needs to be supplied and checked.

4. Experience with products made from multiple castings

Our assembly service page features a whisky bottle cap using 13 die cast components. It is a useful example of how individual castings can become part of a more involved finished product.

We work with joining methods including screw fixings, interference fits, crimping and riveting. The appropriate method depends on the product, its function and the agreed specification. Customers can discuss these requirements with us as part of the manufacturing brief.

For background on the range of joining approaches available to zinc castings, the International Zinc Association’s engineering information on joining provides independent industry context.

5. Quality and packaging considered before despatch

The completed assembly is what reaches your customer or production line, so the final stages deserve attention alongside the casting itself. Visible surfaces, component availability and packaging can all affect how smoothly an order moves into its next stage.

Our assembly team supports customers by maintaining levels of component stock, monitoring finish quality and packaging products appropriately for despatch. The checks and packing requirements for your product should be agreed when the work is quoted.

If you need particular cosmetic acceptance criteria, identification, packing quantities or protection for finished surfaces, include those details in your enquiry. This gives us a clearer basis for discussing a service that fits your business.

Is our zinc die casting and assembly service right for your business?

Our zinc die casting and assembly service is worth discussing if you currently buy castings and arrange the remaining work elsewhere, or if your own team spends time assembling and packing products that could be supplied further along the production process.

• Launching a new product? Discuss tooling, casting, machining, finishes and assembly as one manufacturing requirement.
• Reviewing an existing supply chain? Ask whether coordinating more of the work through one supplier could simplify purchasing and handovers.
• Ordering decorative components? Bring finish expectations and surface protection into the conversation early.
• Working with several bought-in parts? Share the complete assembly requirements so component sourcing and stock needs can be considered.

Our zinc diecasting department produces castings from 6g to 600g and works with ZL5 and ZL2 alloys according to customer requirements. We can discuss whether your component and assembly are suitable for our manufacturing capabilities.

Questions customers ask about zinc die casting and assembly

Can you supply a finished assembly rather than loose castings?

Yes. Jones & Wilkinson offers in-house assembly alongside zinc diecasting and secondary operations. Depending on the agreed specification, a project can include additional components, coordinated finishing and packaging for despatch. Tell us what you want to receive at the end of the process, and we can discuss which stages we can provide. That makes the enquiry about your finished product rather than a casting in isolation.

Can we discuss an existing product as well as a new design?

Both are worth discussing. For an existing product, share the current drawings, the assembly requirements and any difficulties you want to resolve. Perhaps your team coordinates several suppliers, or your castings need machining before they can be used. For a new design, bring us into the conversation before tooling decisions are finalised so the later manufacturing stages can be considered too.

What information helps you quote accurately?

A clear zinc die casting and assembly brief helps us understand your priorities from the outset.

A drawing or CAD model is a useful starting point, together with expected annual demand and likely order quantities. For zinc die casting and assembly, the complete parts list also matters: identify the castings, bought-in items and any customer-supplied components. Include the required finish, important functional dimensions, cosmetic expectations and packaging needs. If some details are still being developed, highlight them so we can discuss the open questions.

Are finishing services carried out in your factory?

Our casting, toolmaking, secondary operations and assembly capabilities are supported by local suppliers for bought-in components and paint or plating. We coordinate those requirements through established supplier relationships. When you enquire, we can explain the proposed manufacturing route for your product and clarify which operations are undertaken in house and which finishing requirements are sourced locally.

How should we compare quotations for a complete product?

Compare the same scope of supply. A price for an unfinished casting covers a different requirement from a price that includes machining, finish, additional parts, assembly and packing. Ask what is included, what you would still need to arrange and which acceptance requirements the quotation covers. This helps your purchasing team make a fair comparison and understand the work remaining after delivery.

Can you advise on tooling versus machining costs?

Yes. Our secondary operations service includes comparing a simpler tool with later CNC machining where that approach may suit lower annual quantities. For your enquiry, the useful comparison is the combined cost of tooling and production over the expected demand. Share your likely quantities so we can discuss a practical manufacturing route rather than assuming the most complex tool is always the best investment.

What happens after we send an enquiry?

We review the information with you and discuss the manufacturing scope we can offer. A zinc die casting and assembly enquiry may involve questions about component design, finish, quantities and the additional parts needed to complete the product. Any delivery expectations or special checks should be raised at this stage so the quotation can be considered against your actual requirements.
