We machine our own manifolds, fittings and gun bodies, wind our own heated hoses and test every assembly before it ships. One supplier for foam machines, spray guns, heated hoses and CNC parts.
Documented quality system and material control behind every heated hose, spray gun and machined component we export.
Each line is produced in our own facility, so specifications, thread standards and spare parts stay consistent across hoses, guns, machines and machined components.
Heated HoseHX-38 / HX-50 / HX-75
PTFE-lined heated hose with an evenly wound heating element, holding material temperature along the full length for foam and polyurea spraying.
Heated HoseHX-P38 / HX-P50
Heated hose assembly supplied with a digital temperature controller and sensor, for cold-climate job sites that need a documented set point.
Spray GunAG-300
High-pressure airless gun with a CNC-machined body, in-line filter and reversible tip, built for continuous coating work on steel and concrete.
Spray GunSG-210
HVLP gun for fine finish work on wood, furniture and small metal parts, with gravity feed cup and three-pattern adjustment.
Outsourcing the fluid body or the manifold means outsourcing the tolerance. We keep machining, hose winding, assembly and testing under one roof in Ningbo.
±0.01
mm holding tolerance on milled parts
Manifolds, gun bodies, fittings and heater housings are machined in our own workshop, so critical dimensions are not outsourced.
25,000
metres of heated hose per month
PTFE-lined hoses are cut, heated-element wound, pressure tested and fitted with connectors on a dedicated line.
Every
gun leak-tested at working pressure before packing
Every gun is leak-tested at working pressure and spray-pattern checked before it leaves the assembly bench.
3,000
spray guns and machines shipped yearly
Two-component foam rigs are assembled, heated, calibrated and run-tested with customer hose lengths.
Customer names are withheld under confidentiality. Results below are taken from order records and buyer feedback after delivery.
Building insulation · Spray foam contractor, Poland
A foam insulation contractor working on roof and façade projects in Central Europe lost material temperature over long hose runs during winter. Viscosity rose near the gun, output dropped and partially cured material blocked the hose, forcing crews to cut and replace sections mid-project.
The hose holds temperature all the way to the gun, and the fittings matched our machine without adapters.
Automotive coating · Coating line integrator, Mexico
An integrator building underbody and primer lines for automotive suppliers was using mixed gun brands. Operators changed tips between stations, clogging was frequent and spare parts inventory had grown to cover four different gun designs.
Industrial equipment OEM · Equipment OEM, Australia
An Australian equipment maker needed hydraulic manifolds for a foam spraying unit. Their local machine shop quoted long lead times and could not hold the bore position tolerance required for the cartridge valves, which delayed assembly of finished machines.
First-article data arrived before the batch, so our assembly line was never waiting on inspection.
Certification is the entry requirement. What buyers actually receive is documented inspection at four stages, from incoming material to the sealed container.
Accredited third-party certification body
Quality management system covering design, machining, assembly and export of spray equipment
Notified body assessment
Spray foam machines and heated hose assemblies supplied to the European Economic Area
Material testing laboratory
Restricted substance control on electrical components, heaters and cable assemblies
Material testing laboratory
Polymer liners, hose covers and coating-contact parts declared against the SVHC candidate list
Four documented checkpoints, each producing a record that can be shared with the buyer before shipment.
Steel, aluminium and polymer batches are verified against mill certificates; heaters and cables are sampled for resistance and insulation.
First-article inspection with CMM report, then patrol checks on bore diameter, thread gauges and surface roughness every 20 parts.
Hoses are tested at 1.5 times working pressure, guns and machines at rated pressure with a documented hold time.
Function run, cosmetic check, packing verification and photo report sent to the buyer before the container is sealed.
Export documentation, trade terms and packing method are confirmed in the quotation, so there is no surprise between order and container loading.
Trade terms
EXW / FOB / CIF / DDP
FOB Ningbo and FOB Shanghai are the default; DDP is quoted on request for EU and North America.
Lead time
20 - 35 days
Samples 5 - 7 days. Standard hoses and guns 20 - 30 days. Custom CNC parts 25 - 35 days after drawing approval.
Minimum order
From 1 set
Heated hose from 100 metres, spray guns from 50 pieces, foam machines from 1 set, CNC parts from 20 pieces.
Payment terms
T/T 30% + 70%
30% deposit with the purchase order, 70% balance before shipment. Irrevocable L/C at sight is accepted for orders above USD 30,000.
Packing
Export carton + plywood case
Hoses are coiled and bagged, guns are boxed with foam inserts, machines are bolted into fumigation-free plywood cases.
Documents
CI / PL / B/L / CO
Commercial invoice, packing list, bill of lading and certificate of origin are issued with every shipment; CE files on request.
Our factory sits in Beilun, next to Ningbo port. Containers are loaded at the factory, photographed and the pre-shipment report is sent before the container is sealed.
Specification guidance written by our engineers, covering hose selection, gun setup and machining procurement.
Hose length, liner material, heating element pitch and controller placement decide whether foam reaches the gun at the right viscosity. This guide explains which specification to check before ordering for cold-weather projects.
Ask our engineers
Airless guns deliver high output on thick protective coatings, while HVLP guns give better transfer efficiency on fine finish work. Here is how to match gun type, nozzle size and air supply to the coating you apply.
Ask our engineers
Tolerance, inspection data, material certificates, batch size and packing method decide whether machined parts arrive ready for assembly. Use these five questions to compare machining suppliers before the first order.
