Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What materials are available for this insert? **A**: According to the directory, the insert can be made from H13 tool steel, copper alloy, or graphite. The choice depends on thermal conductivity, hardness, and operating temperature requirements. Confirm the exact material grade with the supplier. ### Q: What are the typical dimensions and tolerances? **A**: Reference ranges include length 50–300 mm, diameter 10–80 mm, and draft angle 0.5–3 degrees. Surface roughness is Ra 0.4–0.8 μm per ISO 1302. These are directory ranges; actual values must be verified for your specific application. ### Q: How is the insert removed after casting? **A**: The insert is removed through designated access points after the metal solidifies. The design includes draft angles and access features to facilitate removal without damaging the casting. The exact removal method depends on the mold design and insert geometry. ### Q: What standards apply to this component? **A**: Standards referenced include ASTM E18 for hardness, ISO 1302 for surface roughness, ASTM E8 for tensile strength, and ISO 9227 for corrosion resistance. These are verification references; compliance must be confirmed with the manufacturer. ## 6.
