Investment Castings Guide 101: Questions & Answers

What does Hengke Casting focus on?

What information should I send for a quotation?

Send the latest drawing revision, alloy specification, quantity, critical dimensions, finish and delivery destination. These details help Hengke Casting define the scope of your casting enquiry.

How should I choose an investment casting alloy?

Compare the required grades against corrosion exposure, temperature, strength and machining needs. Follow the engineering drawing and application requirements when selecting a material.

How should castings be inspected?

Agree dimensional checks, material documentation and any non-destructive testing requirements before production. Identify critical features and define measurable acceptance criteria in the order.

Which certifications or approvals are required?

Requirements depend on the component and its intended use. Confirm the current certification scope and any project-specific approvals with Hengke Casting before placing your order.

What affects the delivery schedule?

Tooling, sample approval, quantities, machining, inspection and freight all affect timing. Agree a schedule after the technical requirements and delivery terms have been reviewed.

Can I request custom cast components?

Share your drawing, alloy and quantity with Hengke Casting. Custom geometry, machining and finishing requirements should be reviewed before the tooling scope and price are finalized.

How can I compare investment casting quotations?

Compare the same drawing, material, quantity, finish and inspection scope. Separate one-time tooling, unit pricing, packaging and freight so the proposals can be evaluated consistently.

Why review the design before making tooling?

Wall sections, transitions, holes and machining allowances affect the casting route. Early review helps identify features that require discussion before tooling and sampling.

What should sample approval cover?

Review the sample against the agreed drawing, material requirements, surface finish and inspection plan. Record any changes and confirm the drawing revision before repeat production.

How do I prepare a repeat order?

Keep the approved drawing, alloy specification, sample records and packaging requirements together. Confirm quantity, revision and delivery expectations with Hengke Casting for every new order.
