Production
Cutting, rolling, welding, coating and assembly sit in the same hall, so a sprayer travels metres between stations instead of weeks between suppliers. That is how we hold a 15-day lead time on standard models without buying finished goods from another yard.
The workshop runs one shift of 40 people with a second shift added from September to January, when orchard orders for the next season arrive. Frames and tanks are built to stock in the quiet months, then configured to order — tank size, boom width, pump and nozzle set — so a customer never waits for the steelwork.
Every machine carries a build card with the welder's stamp, the pump serial number and the test readings. If a machine comes back for service three seasons later, we can tell you who built it and what it measured on the day it left.

Process
01
Laser-cut plate and a three-roll bender turn flat steel into tank shells and boom sections. 4 mm and 6 mm plate are cut in-house so wall thickness is never a guess.
02
HDPE tanks are rotomoulded by a partner to our mould; steel tanks and frames are MIG-welded on jigs, then leak-tested at 2 bar for 30 minutes.
03
Two coating lines, seven-stage pre-treatment and a 180 °C cure. Standard colours are our red and graphite; OEM orders run to your RAL code.
04
Diaphragm and plunger pumps are assembled and bench-run before fitting; valve blocks are pressure-tested and gauges checked against a master.
05
Boom, plumbing and electrics fitted, then a 30 minute wet test at working pressure with a pattern check at three settings.
Quality control
| Check | Standard |
|---|---|
| Tank leak test | 2 bar, 30 minutes, no drop |
| Pump flow | Within 5 % of rated 100 L/min |
| Spray pattern | CV below 10 % across the boom |
| Boom fold cycle | 20 open/close cycles, no leak |
| Paint adhesion | Cross-hatch 1 mm, no lift |
| Fastener torque | Checked against the build card |
The pattern table is a sheet of water-sensitive paper under the boom. If the dots are not evenly spaced across 12 metres, the machine does not leave — and the nozzle supplier hears about it the same day.
