AR CMC Manufacturing & Batch Quality Control
From cotton-linter sourcing to controlled CMC production, batch testing, COA traceability and export packing.
Quality Control Starts with Raw-Material Selection
Upstream cotton-linter resources in Xinjiang support more consistent raw-material selection before CMC production begins.
Cotton-linter quality influences cellulose purity, reaction stability and the repeatability of finished CMC performance. For this reason, raw-material control begins before the material enters our Foshan production process.
Incoming materials are reviewed against agreed requirements, recorded by source and batch, and stored under controlled conditions before production release.
Cotton-Linter Selection
Raw-material selection focuses on cellulose quality and suitability for the intended CMC production route.
Incoming Material Inspection
Appearance, identity and agreed incoming parameters are reviewed before material release to production.
Source Traceability
Supplier, source and incoming-batch information are recorded to support production traceability.
Storage Control
Materials are identified and stored to reduce moisture exposure, contamination and unintended batch mixing.
CMC Manufacturing Capacity & Production Control
Our Foshan production base combines dedicated processing lines, centralized process monitoring, finished-product handling and environmental support systems to sustain controlled commercial production.
From Cellulose Feedstock to Finished CMC
Eight controlled production stages connect raw-material preparation with finished-product packing.
01
Raw-Material Preparation
Cotton-linter feedstock is prepared for controlled processing.
02
Alkalization
Cellulose is activated under defined process conditions.
03
Etherification
Controlled reaction converts cellulose into CMC.
04
Washing & Purification
Residual materials are reduced through controlled washing.
05
Controlled Drying
Moisture is reduced before particle-size processing.
06
Milling & Sieving
Particle distribution is adjusted for consistent handling.
07
Batch Blending
Finished material is blended before batch sampling.
08
Packing & Release
Approved batches are identified, packed and prepared for storage.
Batch-Level CMC Testing Before Product Release
Finished batches are sampled and reviewed against confirmed specifications before packing and shipment preparation.
Reliable comparison requires clearly defined sample preparation, concentration, temperature, instrument and measurement conditions.
Finished-Batch Sampling
A representative sample is collected from the completed batch.
Agreed Test Method
Measurement conditions are recorded for comparable results.
Specification Review
Measured values are checked against the confirmed specification.
COA & Packing Release
Approved results support COA preparation and packing release.
Finished product moves to packing only after laboratory results have been reviewed against the applicable batch specification.
Finished Product Packing & Export Readiness
Approved products are packed, prepared and checked before container loading and export dispatch.
Industrial Packing
Finished products are packed in 25 kg bags, jumbo bags or other agreed industrial formats.
Warehouse & Pallet Preparation
Packed goods are organized and prepared according to the agreed order and loading arrangement.
Loading Verification
Product, quantity, packaging and loading status are reviewed before container dispatch.
Packing format, pallet requirements and container-loading arrangements can be confirmed according to the order, destination and handling requirements.
Send Your Product Requirement
Share the product name, application, quantity, destination and any TDS, sample photo or document you already have. FSX Chemical will review the information and recommend the next step for quotation, sample matching or product selection.
