Gravity Die Casting

Aluminium CastingAluminium CastingAluminium CastingAluminium Casting

Gravity die Castings are manufactured by pouring molten metal into cast-iron moulds. These moulds are permanent and produce a higher casting rate than Sand Castings. The tooling however is significantly more expensive – with the unit prices significantly lower. Medium to high batch sizes are ideal and can provide great savings.

 

Tooling

It is well known that Gravity Die Casting Tooling is high cost. However, the initial high start up costs can quickly be eradicated because of the low cost unit prices available for high batch sizes.

All tooling is manufactured using state of the art CNC Machinery and fully inspected before production runs can go ahead.

Foundry

A variety of Major Non-Ferrous metal alloys are available for your Gravity die Castings requirements.

Aluminium Alloys – LM5, LM6, LM9, LM16, LM24, LM25, LM27 and LM31

Zinc Alloys – ZL3, ZL8, ZL12 and ZL27.

Finished Casting

Castings are hand finished by our highly skilled work force and checked for accuracy and consistency using specific gauges and jigs. A final shot-blasting process enables anodising, alochroming or painting to be applied without further surface finishes required.

Inspection

Our Aluminium Castings are individually inspected during production and on completion, with Certification and Inspection Reports provided as appropriate, all in accordance to our ISO 9001:2015 standards.

Machining

In-house machined components are thoroughly inspected prior to delivery. Certificate of Conformance or Inspection Reports can be provided as appropriate. We have a fully equipped in-house machine shop that boasts CNC Milling and CNC Turning capabilities. We can, if required, also offer conventional methods of machining!

Surface Finishes

We supply your components complete to drawing specification. This includes a wide variety of post cast finishes. We work with a small group of local companies that are approved suppliers. We have a great relationship and share high levels of trust. We can offer heat treatment (to varying specifications), X-ray, Crack Detection, Anodising, Alochroming, Impregnation, Hot Isostatic Pressing and Plating. We have in house painting services and can offer wet paint or powder coat finishes to a very high standard.

Tolerances

The basic tolerance for Gravity die Castings up to 25mm for both Aluminium and Zinc based alloys is ±0.4. The additional tolerance for each further 25mm is ±0.075.

Quality Control

Stringent quality control procedures apply through the production process, as reflected in our ISO 9001:2015 standards.

Pattern Equipment Manufacture – Combining traditional skills with 3D CAD/CAM facilities to produce high quality tooling and components, quickly.

Packaging

All of our components are packed carefully and securely to ensure they arrive to you in the condition they left us. We use leading courier services and deliver using Express Service (next day delivery). If you require a different type of service, please let us know.

Your Enquiry

Please send us your enquiries via email or give us a call if you would like to discuss your requirements. Ideally, 2d PDF documents will be available and these will be supported by 3D IGES/STEP files. Once we have received your files we will take a look to familiarise ourselves and will give you a follow up phone call. We will then work on a quotation and get this over to you as soon as possible. We are here to help.
