Plastic Injection Moulding FAQs

Malton Plastics

Malton Plastics are a trade/custom plastic injection moulding company founded in 2001, manufacturing plastic components and products to bespoke requirements.

We make a variety of injection moulded parts for various applications. Some of the parts we have made include: tote trays, bottle carriers, nut covers, containers, vacuum cleaner tools, electrical housings and many other parts (the list could be endless).

As a trade injection moulder, we service a wide variety of industries which include but are not exclusive to the following: automotive, medical, construction, electronics, defence, sports and leisure, horticulture, floorcare, retail and other consumer and white goods.

We are located in Pickering, North Yorkshire - click here to view map.

Currently, we operate out of two buildings with a total of 13,000 sq. ft.

Currently, we have 10 injection moulding machines.

Our smallest machine has a clamp force of 40 tonne, with a capacity of 40g

Work with a company that has ISO 9001 certified at a minimum as this is the international standard for Quality Management Systems (QMS).

Plastic Injection Moulding

Injection moulding is a process whereby molten plastic is injected into a mould where it then cools to form the desired shape. For a more in depth explanation, see here (insert link to injection moulding page).

Our range of machines allows us to produce a capacity of 40g from as low as 40 tonne clamp force and a capacity of 1kg from 350 tonne clamp force.

The range of materials to choose from is extensive. You will want to balance the cost of the polymer against the properties you require for your part. If unsure, we would be happy to discuss.

Yes, we increasingly use recycled plastics. We have long established partnerships with materials suppliers and where possible we will recycle any waste in-house.

The MOQ can be as little as you would like. However, this wouldn’t be very efficient. Not only do you need to consider the mould tool cost, but there is also a cost attributed to set-up of the moulding machine for production. This cost is off-set against higher volume production.

Injection Mould Tooling

Injection mould tools will invariably transfer across different manufacturers machines. If changes are required when transferring the costs are minimal . Typical changes Sprue bush, locating ring, ejector coupling and water fittings.

Yes, we have a small tool room dedicated to the production and maintenance of injection mould tools.

Cost will depend on the shape, size, complexity and quantity of component required.

Fully hardened steel is not a low cost commodity, and the work involved in cutting steel for the complex design of an injection mould tool takes expensive equipment, skilled personnel and a lot of time. We will obtain quotes from existing and trusted suppliers. This may be from the UK, Europe or the Far East.

Lead times for the mould tool depend on the size and complexity of the mould tool and the location it is being made.

High quality tooling produced in fully hardened steel should be expected to produce 1 million shots before extensive refurbishment cost.


You don’t need to. This is a specialist area where a design agency would be able to assist you, but we can also help. Here’s a list of things to consider when designing for injection moulding: wall thickness, polymer to be used, draft, side features and feed point/aesthetics.

We require STEP or IGIS files to produce an accurate quotation. However, even if you have a PDF or rough sketch, we can still help with our in-house design service. For more on our design service, see here.

Yes, we can assist with design changes ourselves, or work with your design team.

Yes, we can offer in-house design services. This means together we can take your idea and make it into a workable injection moulded part.

Project Management

This includes our entire injection moulding service. We have the capability to take your idea and produce a finished product with in-house design, prototyping, tooling, manufacture and assembly.

Turnkey means something is complete and ready to use immediately. This means we have the ability to supply you with the complete finished product you require.

To complement our moulding service we can also provide complete sub-assembly of your product and packaging. We also offer pad printing and ultrasonic welding.

Ultrasonic welding is a process which uses pressure and high frequency vibration to create frictional heat to melt and bond separate parts together.

Typically we supply all parts in standard brown cartons. However, working with you or any other customer we assess all options available.

Yes, this is typical within our injection moulding service for current customers as we plan production and stock around your annual quantity and order frequency. If you do not have warehousing ability, then long term stock holding can be discussed.

Yes and no. No we cannot dropship direct to an end-user. Yes, we can dropship pallet and box quantities to your customer after prior discussion.
