What Information Is Needed for an OEM Industrial Blade Quotation?
A complete request for quotation reduces clarification time and helps the manufacturer evaluate manufacturability, material, heat treatment and inspection requirements. You do not need to have every answer, but clearly separate confirmed requirements from information that still needs engineering review.
1. Provide a drawing when available
Preferred formats include PDF for viewing and DXF, DWG or STEP for engineering reference. The drawing should identify units, revision, material, heat treatment, surface requirements, tolerances and critical dimensions.
Mark any dimensions that directly affect installation or cutting clearance. Do not rely on a scaled print for production dimensions.
2. If no drawing exists, send a sample
A physical sample can be measured and reviewed, but the sample condition must be explained. Indicate whether it is new, used, reground, deformed or damaged. If the sample is worn, original dimensions may need to be reconstructed from the machine interface or multiple samples.
3. Identify the machine
- Machine manufacturer and model
- Serial number or production year, if relevant
- Blade position and quantity per machine
- Rotor, shaft or holder photographs
- Original part number, if available
4. Describe the application
Explain what the blade cuts, the size and condition of the feedstock, contamination, operating hours, cutting speed if known and the main production objective. Photographs and short operating videos can reveal details that are difficult to describe.
5. State material and hardness requirements
If the material is fixed by an approved specification, provide the full designation and required certification. If the current grade is unknown, explain the current failure mode and allow the supplier to propose options.
Do not specify hardness alone. The manufacturer also needs the steel grade, blade section and impact condition to evaluate a suitable heat-treatment target.
6. Confirm quantity and delivery plan
State the trial quantity, expected annual demand and required delivery date. Prototype and volume production may use different process planning. If the order is urgent, identify the exact quantity needed to restore operation.
7. Define inspection and documentation
Before quotation, identify any required material certificate, hardness report, dimensional report, first article inspection, marking, packing or traceability requirement. This avoids adding documentation after production has started.

Frequently asked questions
Can WALI quote from an original part number?
The part number helps identification, but a drawing, sample or confirmed dimensions may still be required before production.
Can the first order be a small trial batch?
Trial quantity can be discussed during quotation, particularly when a new material or geometry needs validation.
Will a customer drawing remain the production reference?
The approved drawing and revision should be confirmed before production and used as the agreed technical reference.
