Compact and flexible – our electroplating equipment and systems

Our wealth of experience in electroplating allows Heimerle + Meule to offer a series of top-quality and particularly powerful electroplating equipment.

Electroplating system
In addition to the standard equipment, we also offer systems for special applications, on request.

PGG 10 / 20 / 20 S4 / 60

These units are superbly suited to electrodeposition of precious metals such as gold, silver, rhodium and palladium, for example, as well as other metals with the exception of chromium. The equipment is easy to use, meaning that even people with no knowledge of electroplating can work with it with no problems.

While the small electroplating unit PGG 10 (1.5 and 3.0 l) are preferentially used for electroplating individual pieces, small electroplating units PGG 20 and PGG 60 are suitable for working with larger individual pieces and small-series production.

Compact electroplating unit JUNIOR 500 multiplate

The compact electroplating unit Junior 500 multiplate makes simple electroplating a possibility for even the smallest scale user.

Thanks to the flexible standard kit, it is possible to improve individual pieces of jewellery, either partially or completely, using the equipment supplied (plating pen/tweezers). 

The unit’s principal features:

  • Specially painted stainless-steel casing
  • Infinitely adjustable rectifier 1.5 A/15 V
  • The 500 ml plastic vessels
  • Removable plastic vessel locators
  • Platinised round anode
  • Stainless-steel round anode
  • Tweezers for picking goods
  • Plating pen

The Junior 120 pen plating unit

With the JUNIOR 120 pen plating unit ,gold, silver and rhodium plating can be applied very easily, economically and without appearing blotchy. The unit is particularly well suited for enhancing jewellery with highly complex shapes (e.g. clasps, rings, brooches, necklaces, watches), which would only be otherwise possible using the longer and more expensive covering method. Pen plating with the JUNIOR 120 allows application of layer thickness of around 0.1 μm.

This is how easy it is to work with the JUNIOR 120 pen plating unit: using the tweezers (cathode), connect the part to be electroplated to the pen plating unit, dip the felt tip of the electroplating pen (anode) in the electroplating bath and apply the electroplating liquid to the part to be electroplated. The tip should merely glide across the surface. The part is then rinsed under running water and dried.

Electrolytic polishing units and gold and silver polishing systems

Electrolytic polishing of gold and silver is an economic process for enhancing jewellery by means of polishing, especially for parts with complex shapes. Almost all silver and gold alloys – including centrifugal casting (with the exception of palladium-containing white gold) – can be polished in JUST 5–30 seconds. Even deep and hidden surfaces are given a beautiful sheen. 

You will find details of the required polishing salts under electroplating chemicals under Pretreatment.

PEG 40 polishing unit

The PEG 40 polishing unit was specially developed for easy use in workshops. One workpiece per operation can be polished by the PEG 40. The maximum surface area of a given piece should be no more than 10–15 cm².

PGG M polishing unit

The PGG M unifies two functions in one. The unit makes it possible to polish titanium and stainless steel and to electroplate instruments in the same unit at the flip of a switch.

EP 200 electrolytic polishing unit

Using this standard industrial production unit several parts with a total surface area up to 80 cm² can be polished per operation.

The rectifier’s diverse control options – such as ‘continuous manual’, ‘timer’ and ‘impulse’ – make the EP 200 particularly flexible. This means that both individual parts and whole series can be processed with this unit.

A dry-running monitor is installed on the EP 200 polishing unit to control the bath level. If the bath level falls below a defined minimum, the heating is automatically switched off. A thermostat-controlled heating and cooling system is integrated in the process bath and keeps the working temperature at the optimum level.

Quick and clean – the HT II centrifugal dryer

The HT II hot air centrifugal dryer by Heimerle + Meule allows you to quickly and spotlessly dry dripping-wet metal, glass or plastic parts. Thanks to its quick-acting cover heater, our HT II hot-air centrifugal dryer allows extremely fast, spotless drying – even for complex shapes.

Further information on the HT II can be found in the following table: 

Well designed and powerful – the KRW5 water treatment unit

Our KRW5 water treatment unit is suitable for cleaning loop water. In combination with a separate ion exchange cylinder, demineralised water can also be produced. The maximum throughput is 100 l/h.

The running drag-out rinse water to be cleaned flows under gravity into a raw water collection tank. The water is pumped from this basin, through anion exchange column containing mixed bed resins and to the running drag-out rinsers. Here, a magnetically coupled PP-H (polypropylene homopolymer) centrifugal pump is used. The loop water makes no contact with metal components, thus ruling out secondary reactions. The water quality can be monitored using an analogue conductivity meter at the head of the ion exchange cylinder. 

Further information on Heimerle + Meule’s KRW5 water treatment unit can be found in the following table: 

Fast and efficient precious metal recovery – ELECTROCLAIM

Electrolysis with the ELECTROCLAIM system is suitable for recovering precious metals which may present in moderate to high concentrations in drag-out rinses, spent electroplating baths and stripper solutions.

Up to 1,500 g of gold can be deposited on the three special cathodes in the cell of the ELECTROCLAIM precious metal recovery unit. In addition to the improved flow control in the recovery cell, the special Heimerle + Meule cathodes, in particular, achieve high deposit rates. This also ensures that solutions with precious metal concentrations in the grams range can be exploited to within just a few milligrams in a very short period.

The ELECTROCLAIM, with the rectifier, pump and recovery cell, is compactly packaged into a space-saving casing. The instruments and switches are clearly arranged on an instrument panel. The self-priming pump and easily removable special cathodes make the ELECTROCLAIM particularly user-friendly. Treatment of the special cathodes and recovery of the pure precious metal is carried out economically and professionally at our own refinery.

Details of the ELECTROCLAIM components can be found in the following table:
