About / Quality & sustainability

Control the process, not only the final test.

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

Inspection through the manufacturing chain.

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.

01

Incoming materials

Supplier controls, material identification and inspection requirements before production release.

02

Compound batches

Controlled weighing and mixing, batch identification and required semi-finished material checks.

03

Carcass preparation

Checks on fabric, steel cord, calendared components, adhesion systems and dimensional consistency.

04

Building & vulcanisation

Process parameters, construction arrangement, thickness and cure controls matched to the belt design.

05

Finished belt

Appearance, dimensions, identification and specified physical, adhesion or construction tests.

06

Release & traceability

Order documentation, reel allocation, certification, packaging and release against agreed requirements.

Management systems

Quality, safety, environment and energy considered together.

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.

Production visibility

Manufacturing execution and production-control systems support consistent process information.

Material movement

Automated weighing, intelligent warehousing and AGV/RGV logistics reduce manual handling and improve traceability.

Release evidence

Inspection, test and identification requirements are assembled around the belt and customer specification.

Sustainability

Efficiency across production and product life.

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

Define what must be demonstrated before manufacture starts.

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.
