Incoming materials
Supplier controls, material identification and inspection requirements before production release.
About / Quality & sustainability
Double Arrow describes quality control as a whole-process system covering incoming materials, semi-finished components, production, finished belt testing, identification and release.
Quality approach
Finished-belt testing is important, but it cannot replace control of compound preparation, carcass construction, vulcanisation and traceability. The required control plan and evidence are aligned with the product, applicable standard and customer specification.
Supplier controls, material identification and inspection requirements before production release.
Controlled weighing and mixing, batch identification and required semi-finished material checks.
Checks on fabric, steel cord, calendared components, adhesion systems and dimensional consistency.
Process parameters, construction arrangement, thickness and cure controls matched to the belt design.
Appearance, dimensions, identification and specified physical, adhesion or construction tests.
Order documentation, reel allocation, certification, packaging and release against agreed requirements.
Management systems
Company information identifies a framework of management systems supported by digital production, warehouse, logistics, energy and customer-management tools. Project requirements are still confirmed through the order specification, inspection plan and agreed evidence package.
Manufacturing execution and production-control systems support consistent process information.
Automated weighing, intelligent warehousing and AGV/RGV logistics reduce manual handling and improve traceability.
Inspection, test and identification requirements are assembled around the belt and customer specification.
Sustainability
Double Arrow's public company materials identify photovoltaic generation, intelligent energy management, greenhouse-gas verification and carbon-neutrality work for factory and product scopes. Production improvement also targets material efficiency, energy use and process consistency.
For long-distance conveyors, low rolling-resistance belt development can support system energy studies. Any project benefit must be based on defined conveyor loads, speed, temperature, idler configuration and operating assumptions.
Low rolling resistance ↗Project evidence
Applicable standard, inspection and test plan, witness or hold points, certificate content, identification and document format should be confirmed with the order—not reconstructed after production.
