Our Production Process
At Sino Concept, we control the entire production cycle, from design to packing.
We specialise in plastic-rubber composite, rubber, plastic, and steel products, with strict quality control at every stage.
We design over 90% of our products in-house, own our moulds and tooling, and set our material specifications to ensure consistent quality and full control over every step.
Our teams are based where production happens: our main operations centre in Qingdao (Shandong) and a second office in Taizhou (Zhejiang), where our quality-control team covers our partner factories in the region. Nothing is inspected remotely.
Rubber & Plastic-Rubber Composite
Rubber and plastic-rubber composite products are produced on dedicated lines at our partner factories, with our moulds and our material specifications.
Processes:
- Vulcanisation (rubber)
- Compression moulding (plastic-rubber composite)
Materials:
- Rubber: 90% recycled + 10% virgin rubber
- Plastic-rubber composite: Mix of recycled plastic and rubber
Products:
Speed bumps, wheel stops, cable protectors, speed cushions

Plastic Manufacturing
We also coordinate plastic production at our long-term partner factories, working closely with our partner factories for rubber and steel.
Processes:
Injection moulding, blow moulding
Materials:
PP, PE, PVC, EVA, PU, including recycled options
Products:
Traffic cones, drop-over cable covers, roadwork beacons, plastic sandbags

Steel Manufacturing
Steel products are produced by our long-term partner factories to our designs and specifications, from raw tube processing to surface finishing.
Processes:
Welding, stamping, bending, hot-dip galvanising, powder coating
Materials:
Steel tubes, ductile iron
Products:
Bike racks, crowd control barriers, street barriers, bollards, and street furniture

Custom Manufacturing
Looking for a custom product?
At Sino Concept, we offer tailor-made solutions developed according to your exact specifications, whether it’s a small adjustment or a completely new design.
Our in-house design team works closely with our long-term partner factories to ensure your product is not only technically feasible but also optimised for industrial production.
We focus on functionality, visual consistency, and compliance with international safety standards, to deliver practical, reliable, and well-designed products that match your needs.
This model gives us the control of a manufacturer without the rigidity of a single plant: we choose the right factory for each technology, and we can add capacity without rebuilding a production line.

Quality at Every Step
From raw material selection to final inspection, we apply rigorous quality control procedures to ensure that all products meet technical requirements and regulatory standards.
