SHOT BLASTING · SHOT PEENING · BLAST ROOMS · PAINTING LINES
Shot Blasting Equipment Manufacturer in Jiangsu, China
ABOUT DINGTIAN
We have built wheel blast machines, blast rooms and painting lines since 1998. From a 13,000 m² works in Dafeng District, Yancheng, a team of 126 — six of them design engineers — supplies steel fabricators, foundries, shipyards and pipe mills in more than 40 countries.
Every machine starts with your workpiece
A shot blasting machine is only right or wrong relative to the part you put through it. Before we quote, we ask for the part drawing, the batch weight, the surface standard and the throughput you need — then the wheel count, cabinet size, conveyor pitch and abrasive recovery follow from those numbers.
The same machine is sold under several names depending on where you buy: shot blaster in the United States, wheel blast machine or airless shot blasting machine in Europe, and shot blasting equipment in most tender documents. If you already know which term your specification uses, use it when you write to us — we will answer in the same language.
That is the difference between buying a catalogue model and commissioning a custom shot blasting machine built around your production line. Most of what we ship is the second kind: a standard platform with a modified envelope, a different wheel arrangement or an added paint module.
Standards, not adjectives
Surface preparation is measured, so we quote it as a measurement. In a wheel blast machine the shot blasting process is set by wheel speed, abrasive flow rate, blast time and the geometry of the wheels relative to the work — change any one of them and the finish changes with it.
Which is why our machines are set up to reach the grade and profile your coating system specifies — typically Sa 2.5 or Sa 3 to ISO 8501-1, with a roughness profile to ISO 8503-2.
| Surface cleanliness | Sa 2.5 / Sa 3 to ISO 8501-1 |
| Surface roughness | Rz to ISO 8503-2 |
| Abrasive media | ISO 11124; stainless shot to ISO 11124-6:2025 |
| Cast shot sizing | SAE J444 grading |
| Wear parts | Cast chrome and 40Cr, OEM-compatible |
| Quality system | ISO 9001 certified |
Four families of equipment
Every family below is a surface preparation tool first and a machine second — the question is which surface, at what volume, and to which standard.
- Descaling before coating. Roller conveyor lines for plate and sections, and combined blast-and-paint lines. Roller conveyor shot blasting machine
- Cleaning castings and forgings. Hanger type shot blasting machine and tumble belt shot blasting machine for batch work, plus trolley and turntable designs.
- Cleaning pipe, bar and wire. Steel pipe shot blasting machine for inner and outer wall, bar descalers and wire mesh belt machines.
- Beyond descaling. Shot peening machines, blast rooms with mechanical abrasive recovery, and industrial painting and coating lines.
What happens after you send an enquiry
Most buyers want to know how a Chinese supplier actually runs a project. Our sequence does not change much between a single machine and a full line:
- Application review — we read the drawings and confirm whether a standard model fits or a modified design is needed.
- Drawing and quotation — general arrangement drawing, technical description, price and delivery date, normally within three to five working days.
- Detail design — foundation loads, pit dimensions, power and compressed air demand, dust extraction connections.
- Fabrication and trial assembly in our Dafeng works.
- Factory acceptance test — run with your abrasive, video and dimensional records sent before shipment.
- Shipping, installation and commissioning — remote by video, or with an engineer on site.
Judged in year three, not on delivery day
Blades, control cage, impeller, liners, distributor and abrasive hoses are stocked in standard patterns and ship separately from a machine order, so a shot blasting machine spare parts requirement does not have to wait for a production slot.
We also supply wear parts that fit Wheelabrator, Pangborn and Sintokogio equipment, which matters if you run a mixed fleet. Service is handled by the engineers who build the machines: video diagnosis is free for the life of the equipment, and on-site attendance is quoted per trip with travel listed separately.
Where our machines work
Steel structure fabrication, foundries, shipbuilding and ship repair, line pipe and OCTG mills, wind tower production, automotive components and stone processing. Each industry judges a surface preparation line on a different number — anchor profile, cycle time, residual stress or cost per tonne cleaned — so the reference list we send is chosen to match your application rather than mailed as a catalogue.
Some of that equipment is a standard series machine; some is a bespoke surface preparation system built around a single production line or a single part family. Both are quoted the same way: drawing first, then price.
Today our equipment runs in more than 40 countries, with the largest concentrations in the Middle East, Mexico, Argentina, Brazil, the CIS, South Asia and Northern Europe — markets where buyers compare equipment on measured performance and total cost of ownership rather than on the lowest quoted price.
