How to Send Drawings for a Custom Chute Liner Quote
Sending drawings for a custom chute liner quote is the fastest way to move from a general product inquiry to a practical quotation. A supplier can quote much more accurately when the RFQ includes plate dimensions, material grade, thickness, hole pattern, quantity, application condition and replacement goal.
For chute liners, hopper liners, bolt-on liner plates and processed wear plates, the drawing package does not need to be perfect at the first step. A PDF drawing, DXF file, hand sketch, worn liner photo or measured sample can all be used for initial review if the key dimensions and working condition are clear.

Quick answer: what should be included in the RFQ?
| RFQ item | What to send | Why it matters |
|---|---|---|
| Drawing or sketch | PDF, DWG, DXF, STEP, hand sketch or measured photos. | Confirms outline, holes, bend direction, tolerances and part orientation. |
| Photos | Existing liner, chute position, worn area, bolts, backing plate and installation access. | Shows material flow, impact zone, failure mode and site constraints. |
| Material grade | NM400, NM450, NM500, high chrome, ceramic rubber or current liner certificate. | Controls hardness, processability, impact resistance and price. |
| Thickness | Current thickness, preferred thickness or allowable space. | Affects wear life, weight, bolt length and handling. |
| Hole pattern | Bolt size, hole diameter, pitch, countersink angle/depth, slot details or plug weld holes. | Changes drilling, countersinking, inspection and installation fit. |
| Quantity | Pieces per drawing, full liner-set quantity or annual replacement quantity. | Used for material nesting, MOQ, unit cost and lead time. |
| Application condition | Handled material, particle size, impact height, moisture, temperature and current service life. | Helps select material and fixing method. |
| Destination and documents | Country, port, delivery term, packing, certificates and inspection reports. | Affects packing, logistics and documentation cost. |
Drawing formats accepted for first review
| File or input | Best use | What to check before sending |
|---|---|---|
| PDF drawing | Clear quotation when dimensions, hole pattern and material are already defined. | Make sure scale, units, revision number and tolerance notes are visible. |
| DXF / DWG | Cutting, nesting and repeat production review. | Confirm the file matches the latest approved drawing revision. |
| STEP / 3D model | Curved, bent, cast or assembled liner parts. | Provide 2D critical dimensions as well, especially holes and thickness. |
| Hand sketch | Early RFQ when no formal drawing exists. | Include length, width, thickness, hole coordinates and orientation. |
| Photos with dimensions | Replacement liner review or reverse-engineering discussion. | Put a ruler or key dimension in the photo and mark the wear side. |
| Old liner sample | When drawings are missing and exact fit matters. | Send photos first, then discuss sample shipping if needed. |
Material information to include
If the current liner material is known, include the grade and certificate. If it is not known, describe the application and current service life. The supplier can then compare options such as NM400 wear plate, NM450 wear plate, NM500 wear plate, high chrome cast liner or ceramic rubber composite liner.
| Condition | Common starting option | RFQ note |
|---|---|---|
| General sliding abrasion | NM400 or NM450 wear plate | Good starting point for processed chute liner plates. |
| Heavier sliding abrasion | NM450 or NM500 wear plate | Confirm impact level and hole processing requirement. |
| High impact transfer point | Thicker NM plate, modular design or rubber-backed review | Send photos of impact zone and worn liner shape. |
| Severe abrasive flow with repeat geometry | High chrome cast liner or ceramic composite review | Confirm temperature, impact and whether bolting is required. |
| Fast replacement during shutdown | Bolt-on chute liner plates | Send bolt pattern, access direction and part numbers. |
Hole pattern details that prevent quotation delays
Many chute liner RFQs slow down because the plate size is clear but the hole details are incomplete. For bolt-on liner plates, the hole pattern should be treated as a manufacturing feature, not as a small note.
| Hole detail | What to specify | Why it matters |
|---|---|---|
| Through holes | Hole diameter, bolt size, pitch and edge distance. | Controls fit and replacement speed. |
| Countersunk holes | Countersink angle, head diameter, depth and remaining thickness. | Prevents bolt-head projection and weak remaining plate section. |
| Slots | Slot width, length, radius and orientation. | Allows adjustment but changes cutting and inspection time. |
| Plug weld holes | Hole diameter, pitch, weld side and grinding requirement. | Important when rear bolting is not possible. |
| Tolerance | General tolerance and critical hole-position tolerance. | Tight tolerance increases inspection and processing cost. |
How the quotation process normally works
- RFQ review: drawings, photos, material, thickness, quantity and application are checked.
- Technical clarification: missing hole details, fixing method, inspection documents or packing requirements are confirmed.
- Material and process suggestion: NM wear plate, cast liner, composite liner or processed plate route is selected.
- Quotation: price is calculated by material, thickness, cutting, drilling, countersinking, quantity, inspection and packing.
- Drawing confirmation: production drawing, revision and part list are confirmed before manufacturing.
- Manufacturing and packing: plates are cut, drilled, inspected, marked and packed for shipment.
