Frequently Asked Questions
How does CZT ensure dimensional repeatability across large production batches?
CZT uses hardened steel tooling with controlled shot parameters including injection pressure, temperature, and cooling time. Statistical process control (SPC) is applied to critical dimensions, and CMM inspection is performed on a sampling basis per batch to verify conformance to drawing tolerances.
What is the thermal conductivity of the die-cast alloy used in QSFP Structural Part 5?
Zinc alloys used in this application typically exhibit thermal conductivity of 100–115 W/m·K, while aluminum alloys offer 140–160 W/m·K. The specific alloy is selected based on the module's thermal budget and mechanical requirements, and can be specified by the customer.
Does this part require secondary machining after die casting?
Most critical features are net-shape from the die casting process, minimizing secondary operations. However, CZT can provide post-cast CNC machining for features requiring tighter tolerances than die casting alone can achieve, such as precision bore diameters or threaded inserts.
