Pump magnetic cylinder

The Pump magnetic cylinder is produced by Aunov Tech from stainless steel, formed and finished under one roof. In operation, the fuel pump component seals the fuel-wetted chamber and locates the pump internals. Forming, machining and inspection share one floor, so the approved sample defines every later batch under one roof.

Product overview

For this metal pump, the drawing centres on, wall thickness control, flange geometry and the sealing surface, all held to the drawing and verified at first article.

Forming, machining and finishing for this metal pump happen on one site, so a change of wall or hole does not restart the programme, and the same die can be re-cut from the original data.

From coil to finished part

Manufacturing runs on a controlled process path: Coil is blanked and then drawn down in successive stages; after drawing, critical faces are machined and the part is degreased and gauged.

Route cards follow each pump magnetic cylinder batch through the shop, so the next run starts from the data that already worked. Any change to the pump magnetic cylinder drawing is re-approved and re-verified before production continues.

Materials and finishing

Materials kept on the floor cover carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal pump is costed in carbon steel or stainless.

Coating selection follows the duty – indoor, outdoor or under-hood: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this metal pump, so the decision never has to be made twice.

Route cards follow each pump magnetic cylinder batch through the shop, so the next run starts from the data that already worked. Any change to the pump magnetic cylinder drawing is re-approved and re-verified before production continues.

Quality control

An ISO 9001 certified system governs production: mill certificates cover every delivery of stock, the CMM measures the first article dimension by dimension, and run inspections follow an agreed sampling plan. On the fuel pump component itself, leak testing is available on request, and every first article is measured for bore finish and groove geometry. Torque, leak and pressure tests are available where the assembly needs them, and the batch file carries the results.

Typical applications

The metal pump is specified into fluid power and pump assemblies for OEM and Tier-1 customers.

One drawing for this metal pump is commonly applied to several programmes, so the tightest tolerance in the family sets the spec, and the die does not have to change.

DesigningSend drawings, or send a sample to be measured – DFM notes are returned before any tooling is cut; the same drawing is used for every repeat order.
ToolingProgressive and drawing dies are designed and built in house, so a die can be re-cut against the approved drawing, and first-article timing is measured from the tooling start date.
SamplesSamples are issued for approval before the run, so the sample is retained as the master, and the signed sample is kept for future reorders.
MaterialsMaterials held include carbon steel, 304 / 316 stainless, aluminium and brass; mill certificates and heat numbers accompany the first article.
Surface finishFinish selected from the drawing: plating, coating, anodising or passivation; finish thickness and adhesion checked on the first article.
ProcessingProgressive drawing through several stages, annealed between draws, then trim and pierce; every stage is logged against your part number.
Equipment5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line, backed by CNC turning centres and a climate-controlled inspection room.
Tolerance+/-0.05 mm on drawn diameters, tighter bands confirmed against the drawing; GD&T per drawing, PPAP-style reports on request.
Delivery termsFOB, with DDP offered for EU and US addresses, payment by T/T, L/C at sight or D/P; call-off schedules are supported.
