Quality Control
Tile Backer Board Quality Control Process
ANGESEN manages quality from raw material review and in-house XPS core control to finished board inspection, packaging readiness, and shipment documentation.
Quality Overview
How does ANGESEN control tile backer board quality?
ANGESEN supports tile backer board quality control through raw material checks, in-house XPS core production, production monitoring, finished board inspection, carton or pallet packaging review, and shipment documentation for distributor and OEM/private label supply.
Process
Quality checkpoints from core material to shipment
Raw Material Check
Review incoming materials, approved specifications, and batch identification before XPS core or finished board production.
XPS Core Control
Check in-house XPS core density, weight, dimensions, appearance, and applicable environmental test records before composite production.
Composite Process Control
Monitor coating, fiberglass mesh, bonding, board formation, surface condition, and process consistency during composite production.
Finished Board Inspection
Inspect length, width, thickness, diagonal, flatness, weight, surface, edge, bond performance, and order-specific marking by batch.
Packaging and Loading Check
Review carton or pallet condition, labels, protective materials, quantities, pallet condition, container loading, and agreed shipment evidence.
Batch Inspection Plan
Five quality stages from incoming material to container loading
ANGESEN separates quality review into raw material, XPS core, composite process, finished product, and packaging/loading stages. The sampling basis follows the batch, approved product specification, and order requirements.
| Stage | Typical Checks | Inspection Basis |
|---|---|---|
| Raw material | Incoming condition, approved material reference, supplier or batch identification, and production readiness. | Checked by batch and against the approved order or internal material requirement. |
| XPS core | Density, weight, dimensions, thickness, flatness, appearance, and applicable environmental test records. | In-house core checks by batch; environmental testing is also arranged periodically through third-party laboratories. |
| Composite process | Surface coating, fiberglass mesh condition, bonding, dimensions, forming condition, and visible process consistency. | Production monitoring and batch checks during finished board manufacture. |
| Finished product | Length, width, thickness, diagonal, flatness, weight, surface, edge, bond strength, compressive strength, water absorption, and thermal conductivity where applicable. | Sampling follows the batch, product specification, and order requirement rather than one public fixed percentage. |
| Packaging and loading | Board or carton marks, barcode and batch data, carton or pallet condition, protective materials, quantities, container condition, and loading record. | Reviewed against the approved packing and shipment plan before release. |
In-house Inspection Capability
Equipment used to support product and batch review
Compressive strength testing
Equipment is available for checking compressive performance against the applicable product or order requirement.
Bond and pull-off testing
Bond-strength and pull-off testing equipment supports review of the board surface and composite structure.
Water absorption testing
Immersion testing equipment is used for applicable water-absorption checks and product review.
Density and weight control
Density and weighing equipment supports XPS core and finished product consistency checks.
Dimensions and flatness
Length, width, thickness, diagonal, and flatness tools are used for batch and order-specific dimensional checks.
Thermal conductivity testing
Thermal-conductivity equipment supports applicable technical review and product-data confirmation.
Buyer evidence available by order
Evidence is prepared for the applicable order scope. Buyers should confirm the required inspection and document package before production or container booking.
- Product inspection data prepared for the applicable order scope
- Packaging photographs showing carton or pallet condition and markings
- Container-loading photographs and a loading quantity list
- Video inspection when agreed before shipment
- Cooperation with a buyer-appointed third-party inspection company
Procurement Inspection Matrix
What procurement teams should ask during tile backer board QC review
A useful quality review connects the product specification with the buyer's market, application, packaging, and documentation needs. For distributor and OEM programs, the goal is repeatable board supply, not a one-time visual check.
Review focus
Tile backer board procurement QC should review XPS core consistency, board dimensions, surface condition, application fit, carton or pallet packaging, and document scope before wholesale or OEM approval.
| QC Checkpoint | What Is Reviewed | Buyer Question |
|---|---|---|
| XPS core consistency | Core material condition, density consistency expectations, board structure, and whether the core is suitable for the requested board program. | How does the factory control the core material before finished tile backer board production? |
| Board dimensions and surface | Board size reference, thickness target, surface condition, edge condition, and visible defects before packaging. | Can the supplier keep the same board size and surface presentation for repeat distributor orders? |
| Application and system fit | Whether the product scope matches shower walls, bathroom floors, wet rooms, shower trays, niches, curbs, or accessories. | Is the requested product being reviewed for the correct application instead of being quoted as a generic board? |
| Packaging readiness | Carton or pallet packaging, label content, handling needs, private label scope, and export readiness. | Will the packaging work for warehouse handling, local distribution, and contractor-facing sales? |
| Document scope | Product data sheet, installation reference, certificate facts within product scope, sample notes, and shipment documents. | Which documents should procurement review before approving a 40HQ wholesale or OEM order? |
Buyer Checklist
What buyers should confirm before quality review
Quality review is more useful when buyers define the intended market, product scope, and shipment plan before requesting documents.
Quality Control FAQ
What does ANGESEN check before tile backer board shipment?
Factory-side checks can include raw material condition, XPS core consistency, board dimensions, surface condition, packaging readiness, and shipment documentation.
Why is XPS core control important for waterproof backer board buyers?
The XPS core affects board consistency, weight, handling, and repeat-order stability. ANGESEN's in-house XPS core workshop helps the factory manage core material before finished board production.
Can ANGESEN provide quality documentation?
Yes. Depending on the agreed order scope, ANGESEN can provide product inspection data, packaging and loading photographs, a loading quantity list, video inspection, and cooperation with a buyer-appointed third-party inspector.
Does ANGESEN use one fixed sampling percentage for every product?
No single public percentage applies to every product and order. Sampling is arranged by batch and according to the product specification, customer requirement, and agreed inspection scope.
How are nonconforming products handled?
Nonconforming products are isolated from conforming goods and reviewed before disposition. They are not released as conforming shipment goods without an approved handling decision.
Are inspection instruments maintained or calibrated?
ANGESEN maintains calibration or maintenance records for applicable inspection equipment as part of factory quality control.
Does ANGESEN publish public prices or guaranteed performance claims on quality pages?
No. Pricing depends on specification, packaging, quantity, and shipment plan. Performance and certification information should be reviewed within the correct product scope.
Who should use the quality control page?
The page is designed for distributors, importers, wholesalers, OEM/private label buyers, contractors, and builders evaluating tile backer board factory supply.
