Manufacturing process

From requirements to production

Each project begins with the buyer's product requirements. Chandar then reviews feasibility, tooling, sampling, production, inspection, packaging, and shipment needs.

  1. 01

    Project requirements

    The buyer provides a drawing or sample photo, target quantity, surface requirement, packaging need, and destination market.

  2. 02

    Feasibility review

    Chandar reviews casting feasibility, tooling needs, finishing requirements, inspection expectations, and other project requirements.

  3. 03

    Project quotation

    Chandar prepares a quotation based on design complexity, tooling requirements, material, surface finish, packaging, and order quantity.

  4. 04

    Tooling and sample plan

    If custom tooling or a sample is required, Chandar confirms the tooling, sampling, and approval plan before production.

  5. 05

    Production requirements

    Chandar confirms the casting, finishing, surface-treatment, inspection, and packaging requirements against the approved sample or specification.

  6. 06

    Inspection and shipment preparation

    The agreed project plan defines the dimensional, surface, packaging, labeling, and pre-shipment checks required before dispatch.

Quality control

Checks defined for your project

Inspection and testing requirements are agreed for each project from the drawing, finish specification, packaging plan, destination, and applicable document requirements.

  1. 01

    Material requirements

    The buyer identifies any material grade, composition, traceability, or batch-document requirements, and Chandar confirms what can be supported for the project.

  2. 02

    Tooling and sample approval

    When custom tooling or sampling is required, the buyer and Chandar agree the approval criteria before production.

  3. 03

    Casting criteria

    The project specification can define casting and visible-surface criteria appropriate to the part and its application.

  4. 04

    Dimensions and fit

    The buyer marks critical dimensions, fit surfaces, and assembly interfaces so Chandar can confirm the applicable inspection plan.

  5. 05

    Surface finish requirements

    The confirmed specification defines the coating or surface-finish requirements and any related acceptance criteria.

  6. 06

    Packaging and pre-shipment review

    The buyer provides packaging, labeling, carton or pallet, and destination requirements so Chandar can confirm the project-specific pre-shipment plan.
