Equipment Capabilities

Liquid silicone rubber consists of two material components that are accurately metered, mixed, and delivered to the injection unit. The material is injected into a heated mold, where it cures to form flexible components with fine geometries and stable functional properties.

ARBURG configures its ALLROUNDER machines for silicone processing with material-specific dosing, temperature-controlled cylinder and nozzle systems, and process-control functions designed to prevent premature curing before the material enters the mold.

The equipment supports the production of:

• Medical-related silicone components
• Seals, gaskets, and diaphragms
• Flexible valves and functional parts
• Electrical insulation components
• Small precision LSR products
• Silicone overmolded components
• Mold-trial and repeat-production parts

Automated Production Cell

The machine is operated with auxiliary equipment for LSR metering and automated part handling. After each molding cycle, the handling system can remove the finished component or runner and transfer it to an inspection, collection, or downstream processing area.

This arrangement helps maintain repeatable cycle timing and reduces unnecessary manual contact with newly molded components. ARBURG provides silicone-processing systems ranging from process-equipped ALLROUNDER machines to integrated turnkey production cells.

Role in Our Manufacturing Process

The German ARBURG ALLROUNDER 370 S forms part of our in-house liquid silicone manufacturing workflow, connecting mold preparation, material dosing, injection molding, automated handling, inspection, and controlled product transfer.

Operators monitor material ratio, injection conditions, mold temperature, curing time, demolding, and component appearance during production. Finished parts are inspected for incomplete filling, flash, deformation, contamination, and surface irregularities before proceeding to trimming, cleaning, assembly, or packaging.

Actual molding conditions are determined according to the LSR formulation, mold structure, component geometry, cleanliness requirements, dimensional tolerances, and project specifications.
