What is the REINER® casting method particularly good for?

What is special about the Z410 zinc die-casting alloy?

The Z410 metal mix was developed as early as the 1930s. It is a special alloy for hot-chamber zinc die-casting with 3.8-4.2 % aluminium, 0.7-1.1 % copper and 0.035-0.06 % magnesium. This zinc die-casting alloy is suitable for very thin walls in stable forms and offers special surface properties. The material is suitable for all the common surface refinement procedures.

How expensive is the zinc die-casting method?

Parts can be produced in small or medium-sized batches at REINER®. Our dedicated tool development, mould and tool construction keep the costs for REINER® relatively low. Depending on the use case, this production method requires no mechanical post-processing, which also reduces costs.

Precise statements on this are not possible, of course, since this always depends on the customers' requirements and the number of parts produced. The zinc die-casting method used by REINER® is generally deemed a cost-efficient option.

How environmentally compatible is zinc die-casting?

The material is a heavy metal. Zinc die-casting at REINER® is therefore subject to special environmental provisions. Since the environment is important to REINER®, we place special value on re-using any residues that arise.

The good strength-weight ratio of the die-casting parts and a relatively low casting temperature greatly reduce the strain on the environment. Material savings by thin-walled casting and longevity of the cast parts makes this method highly resource-efficient and sustainable in the long run.

What is zinc die-casting?

In zinc die-casting, REINER® presses the liquid zamac into a pre-fabricated, customised mould at high pressure. 
The cast parts made by REINER have a very high quality subject to continuous review.
Additionally, we offer subsequent surface treatments through our comprehensive partner network, including galvanically/chemically treated surfaces, coatings (e.g. KTL), powder-coatings, etc.

What parts can be made by zinc die-casting?

This method can be used, e.g., to cast the following small parts:
  • Parts for electronic components, such as plug connections
  • Small parts for engineering
  • Medical accessories, such as pump housings, spatulas, stethoscope parts, parts for microscopes
  • Complex pressure wheels
  • Zippers
  • Toy cars
  • Model train parts
  • And many other parts

What are the advantages and properties of zinc die-cast parts?

The resulting zinc parts are highly resilient against corrosion and other normal atmospheric conditions. Even moist, industrial and oily environments are not an issue. Resilience can be improved further with the matching surface treatment. REINER® zinc-cast parts do not produce sparks and are not magnetic, but conduct heat and electricity.
