Our Production Process: From Design to Delivery
We design our products, we own the moulds, and we control how they are made.
Sino Concept has been manufacturing traffic safety equipment, event equipment and street furniture since 2009. We are not a trading company. We do not buy finished products from a catalogue and resell them. Every product we sell is our own design, made with our own moulds, to our own material specifications.
Our products are made through our own production network in China. Each factory in this network is specialised in one technology: rubber, plastic, or steel. We choose the right one for each product, we supply the moulds and the specifications, and our own staff work inside those factories.
This gives us the control of a manufacturer without the limits of a single plant. When demand grows, we add capacity where the process already runs well, instead of rebuilding a production line. It makes us faster and more flexible: we can move quickly on a new product, on a large order, or on a technology we do not use every day.
We have two centres in China:
Qingdao (Shandong Province)
Production and operations. Design, moulds, supplier management, planning and export.
Taizhou (Zhejiang Province)
Production and quality control for the factories in our network in that region.
Plastic-Rubber Composite Moulding
Hard-wearing products at a competitive price
Plastic-rubber composite is our most used process. Recycled rubber and recycled plastic are mixed and heated until the compound is soft. It is then loaded hot into the mould and compressed. The part takes its final shape as it cools inside the mould.
The result is a heavy, solid product that resists impact, UV and frost, at a lower cost than vulcanised rubber.
Process: material preparation → mixing and heating → hot compound loaded into the mould → compression → cooling in the mould → demoulding → trimming and finishing → inspection.
Materials: recycled rubber and recycled plastic. The mix is set by us and adjusted for each product.
Products made with this process:
- Speed bumps and speed humps
- Speed cushions
- Wheel stops and parking blocks
- Lane separators
- Standard range cable ramps: 2-channel, 3-channel and 5-channel
Vulcanised Rubber
For products that take real punishment
Vulcanised rubber is used where a product has to bend, take heavy loads and stay outside for years.
Here the heat works the other way round: the rubber compound is placed in the mould, then cured under heat and pressure. This changes the structure of the material itself. The part becomes flexible but very strong, and it keeps its shape under vehicle loads.
Process: rubber preparation → compound mixing → mould preparation → vulcanisation under heat and pressure → surface finishing → inspection.
Materials: selected recycled rubber. We control the compound for each product, to keep quality, hardness and odour consistent from one batch to the next. Our rubber materials comply with REACH (EU).
Products made with this process:
- Heavy-duty cable ramps and cable protectors
- Rubber protection products for industrial sites
Cable ramps are one of our main product families. They are used on construction sites, in industrial buildings and at events, where cables and hoses have to survive vehicle traffic.
Plastic: Injection and Blow Moulding
Light products, precise shapes
Some products need to be light, bright and easy to stack or carry. For these we use injection moulding for solid parts with precise shapes, and blow moulding for hollow parts such as bases and bodies that can be filled with water or sand.
Process: material preparation → moulding (injection or blow) → cooling → trimming → assembly and finishing → inspection.
Materials: PP, PE, PVC, EVA and PU, including recycled grades where the product allows it.

Steel Fabrication and Surface Treatment
From raw tube to finished, coated product
Steel products are made to our drawings, from raw tube and sheet through to the final coating. Surface treatment is not an option on these products: it decides how long they last outdoors.
Process: cutting → stamping → bending → welding → assembly → surface treatment → inspection.
Surface treatments: zinc plating, hot-dip galvanising, powder coating, or galvanising plus powder coating for coastal and de-icing salt environments.
Materials: steel tube and sheet, ductile iron.

Customisation and Contract Manufacturing
Around 30% of our production is custom-made
Because we own the moulds and the designs, we can change them. Around 30% of what we produce is not a catalogue product.
Customising a standard product
The fastest route. We start from a product we already make and adapt it:
- Your logo moulded or printed on the product
- Custom colours
- Custom reflective film layout
- Your own cartons, labels and barcodes
This lets you sell the product under your own brand, with no mould investment and no long development.
Contract manufacturing
For a product that does not exist yet, or for a product you already sell and want to move to a new supplier.
We can start from a technical drawing, an existing sample, or just a sketch and a specification. We then handle design and design-for-manufacturing, mould and tooling development, material selection, samples, and mass production.
We work in rubber, plastic and steel, from first prototype to full container production. Your project stays confidential, and moulds developed for your project are used for your products only.
Quality Control at Every Step
Checked in the factory, not on paper
Our quality control staff are on the production floor every day, in Qingdao and in Taizhou. They check:
- Incoming raw materials
- The first article, before the run starts
- Dimensions and weight during production
- Surface finish, coating thickness and reflective film position
- Assembly and function
- Packaging and labelling
- Container loading, before the doors are closed
Products are checked against the specification agreed with you, not against a general standard. If something is wrong, it is found in the factory, while it can still be fixed.
