Engineering & simulation

We don't just develop the coating. We engineer the production process.

Savroc models every TripleHard® project on the customer's own parts before equipment is ordered, from a converted open-tank line to a new continuous line, designs it with the customer's engineers and commissions the process in the customer's plant.

How a project runs

We design it with you. Our partner builds it.

    Savroc with you
Blue steps are Savroc's, alone or with your team. The white step is the build: a new line by our equipment partner, or your existing line converted to our plan. Every phase is described on Working with Savroc.

Every phase, step by step

Simulation before deployment

Modelled for your parts before anything is built.

Every project is modelled on the customer's parts before equipment is ordered, whatever the coating work: an open-tank line being converted or a new continuous line. Electrolyte flow, gas and the current field in one model of the bath or the cell. A design change is a new run, not a new prototype, so variants are compared in hours.

3D flow paths in a plating cell: jets from the inlet ring run along the rod inside the anode, leak out through the anode mesh and circulate back through the tank
One plating cell, one model: flow paths from the inlet jets along the rod, out through the anode mesh and back through the tank. Colour is velocity.
  • Side section of the plating cell with streamlines: a fast band along the rod and large circulation loops above and below it

    Where the electrolyte flows

    Side section of the whole cell: the fast stream along the rod and the two large circulations above and below the anode that keep the tank floor moving.

  • Heat map of gas fraction between the rod and the anode along the cell length

    Where hydrogen collects

    Gas fraction around the rod along the cell. Hydrogen gathers where the flow is weakest, so the flow is designed around it, not the other way round.

  • Current field streamlines at the entry and exit of the anode, with the bushings at both ends

    How current reaches the rod

    Current field at the entry and exit ends, with the gas included. It shows where the layer builds evenly and where an end effect needs a design answer.

  • Enlarged flow streamlines inside the entry and exit bushings of the cell

    What the bushings do

    The rod passes through a bushing at each end of the cell. The model shows the flow inside them, so nothing is left to guesswork where the rod enters and leaves.

Scenarios, one model

Change one thing and see what it does.

The same model with a different setting: more flow, a shorter anode, another part. Pick one and the flow paths change, and with them what the part gets along its whole surface. Each variant is an answer in hours, not a trial on the line.

From model to printed part

Five variants on screen. One ring on the printer.

Hydrogen gathered around the rod in the second half of a cell. Five inlet-ring designs were compared in the model, and the best one was 3D-printed and fitted.

Sized for your volumes. Configuration, size and line speed come from simulating your diameters, coating thickness and volumes, not from a catalogue.

Savroc does not offer contract coating. TripleHard® is already tested and in industrial use, so a project starts from the simulation of your parts; samples are coated only on special request.

Engineering questions

What does Savroc need to start a simulation?

Part drawings or a diameter and length range, the specifications the parts must meet, the target annual volume and coating thickness, and for a new line the plant: the floor area and height available, power and water supply, and ventilation.

Can simulation images be shared?

Simulation results are customer-specific and shared only with that customer. Published examples are approved, non-customer-specific images.

Does Savroc build the line?

No. Savroc designs the process and the line concept with the customer and commissions the process in the customer's plant. A new continuous line is built and delivered by our industrial equipment partner, and the customer orders the line from them.
