Cost effective solutions to reburbish and repair your equipment
As the South Island licensee for TEI (NZ) Ltd, we are trained and certified to carry out electroplating repairs using the SIFCO process
onsite or at our workshop in Parkhouse road.
Parkhouse road workshop
Our team work from their Christchurch based workshop.
From here they can meet all your repair requirements with a rapid response and turn-around time.
You can deliver or courier your metal components to us to carry out the work as per your requirements.
Onsite repairs
In some circumstances the component requiring repair may be too large and awkward to transport, or it may be very expensive to dismantle and need a part of building to be demolished or dismantled to get it lifted out.
We provide a professional mobile service where we can bring our equipment to the work site and carry out the repair with the minimum of dismantling and disruption.
For all your hydraulic ram repairs, cylinders, worn seal or bearing diameters, general machining or engineering, Contact us to see how we can help.

The Sifco Process ®
With over 50 metal and alloy solutions to meet the most demanding selective plating applications.
The SIFCO Process® has been utilized for over 50 years on both OEM components and on parts requiring refurbishment in the aerospace, oil and gas, power generation and general industry.
Released by Sifco’s Marketing Department demonstrates The SIFCO Process®. The video combines digital animation and actual video footage of plating to better demonstrate the process and highlight its unique features and benefits.
Over the years I have developed a wealth of experience in the engineering and now the selective electroplating industry.

I have worked for M.S.Coombes for 6 years, completing a national certificate in mechanical engineering, Fitting and Turning.
Further adding 6 years for PSL Total Air specializing in compressed air, vacuum and pneumatics.
Then spending 2 years with Zealandia Horticulture carrying out maintenance and ground works on all equipment.
September 2023 taking over TEI South Island from Barrie Newenham and being trained in the selective electroplating process.
Electroplating is a process commonly known as Electrolysis. Electrolysis producing a chemical change by passing an electrical current through to the electrolyte (solution). The ions migrating to the electrodes, the positive ions which are the metal being deposited are attracted to the negatively charged electrode (the part being plated). The negative ions are attracted to the positive electrode (Anode) and given off as gases.
What is Brush Plating?
The theory of brush plating is very basic. The part to be plated is given a negative (-) charge through a flexible wire lead from a special D.C. power pack. The plating tool or “brush” is positively ( ) charged from the same power pack by a second insulated flexible lead. The plating tool assembly consists of an insulated handle with a graphite or stainless steel anode. The anode is covered with an absorbent material such as Dacron felt. The plating tool is then dipped into the desired plating solution and rubbed over the area where the coating is desired the plating only takes place where the anode contacts the part. The operator must maintain movement between the anode and the part to ensure sound metal deposits.
Which industries and applications can use it?
Navy & Marine
Aircraft & Aerospace Industries
Printing Industries
Electrical & Electronic Industry
General Engineering including mould and die making.
What advantages does Brush Plating have?
Portability
Ease of operation
Rapid metal build up
Disassemble of machines
Plating of larger parts that won’t fit in a tank
Excellent Adhesion
Dense coatings
No thermal distortion
Minimize hydrogen Embrittlement and reduces waste
What disadvantages does Brush Plating have?
Difficulty in plating complex shapes. In most cases, only one part at a time and it is a very labour intensive operation.
What is the meaning of Selective Plating?
Selective plating means that you can selectively plate an area by the means of masking off areas that need not be plated with either masking tapes or masking paints. Just like painting the material on. The job becomes the canvas or Cathode and the brush is the Anode and the paint is the metal.
Does Brush electroplating have the same approvals as tank plating?
Brush plating is approved to many standards. Brush plating has many of its own approvals and these can be supplied from Sifco on request. Many marine, electrical, aircraft and military bodies approve brush plating.
