Just as the word suggests, an adhesion template is used to ‘glue’ a wax model to a branch. Whenever a wax model is injected using a single series matrix, this must then be “treed up”. This is done by placing the products in an adhesion template. The product is then joined to the branch with a hot soldering iron. This means that all products are glued on to the tree in the same way and with a constant intermediate distance. This ensures a uniform method of adhesion and stable product quality.

After the steel products have been cast, the ceramic layer is removed and the products are vibrated or sawed off the steel trees. After the product has been sawn off, a larger “remnant” gate remains attached to the product. By using a chopping jig, the product is always set up and sawn off in exactly the same way. This also keeps the products from being sawn through by accident or from having various lengths of remnant gate remaining attached to the product. Moreover, this prevents damage.

After the product has been sawn or vibrated off, a small “remnant” gate remains attached to the product. This remainder can be sanded off using a sanding jig. As with the chopping jig, the product is always sanded in the same manner, so that every product is identical. By working with a sanding jig, you are guaranteed high precision and constant product quality. The cut can no longer be found on the product after sanding.

CIREX has the knowledge to develop product-specific alignment jigs. This allows the casting to be signed to correct the measurements even more accurately. Sometimes even mechanical post-processing can be prevented. The use of an alignment jig is necessary for this. The mold is closed using a hydraulic press. By loading the product under pressure, plastic deformation occurs and the casting takes the shape as defined in the alignment jigs.

After the products have been sawn off, sanded and blasted, they are inspected for their functionality and dimensions. Products are placed in an inspection template to make sure that they fit during assembly. Using an inspection template makes it impossible for products to be delivered that do not comply with the specifications for dimensions and functionality. With this approach it is not necessary to measure all the products separately on a measuring machine. Proper dimensioning of the precision castings produced by CIREX is nonetheless safeguarded. An inspection template need not be developed for every product. The requirement depends on the functionality, geometry and dimensions. These are the specifications that define the function of the component.

After casting steel components, additional bench work processing may be necessary. This may be milling or routing, or drilling and tapping threaded holes. In order to perform a process well, a clamping jig is developed and produced for each product. A clamping jig is a tool to clamp the products securely and then to guarantee a stable process
