Pre-production tool trials allows us to fine tune the production mold design, and provide a large number of prototype parts.
Once the tool production is complete, the tools are sampled for the initial evaluation of the product. ARC’s Process Engineers work to establish a stabile molding process. Samples of the initial trial are provided to our QA department for a complete dimensional analysis. Once the dimensional analysis is completed, the project leader verifies conformance to specifications. Once the initial samples are produced, actual dimensional shrinkage calculations are used to fine-tune the product to the targeted dimensions. If the tooling feature needs to be adjusted based on the initial trials, a subsequent sampling is conducted. Samples of the second trial are again provided to the QA department for dimensional analysis. This process continues until all customer requirements are satisfied.
At ARC Tooling we work with Haitian injection machines and trial all tools with clamping force below 360 Tons in-house. All machines with separate heaters, flow metering systems, and water cooling systems (7 BAR 15˚Celsius). Larger tools are trailed by ARC’s process engineers at selected trial shops. Full measurement reports and machine settings are always provided after each trial.
The purpose of this procedure is to document mandatory inspection points and to ensure compliance to Project requirements. The inspection is made in two separate steps. The Mould inspection and the Final inspection.
The Mould inspection covers 69 technical points from sprue bushing hardness to isolation plate tolerances. It is checked and approved by our tool inspector, Master builder, Project leader and Q supervisor. All to ensure each tool is up to ARC standard.
The Final inspection covers everything needed to approve a tool for shipment, such as pressure test to 20 Bar, Assembly, Cooling etc.
Every tool that leaves our factory will have been thoroughly tested and inspected to ensure it can run with maximum efficiency when it arrives.
