DSC – Dip Spin Conveyor

With the use of our DSC coating system, the goods are transferred from the electroplating process to the centrifuge drum immediately after the electroplating process. The Dip Spin Conveyor transport trolley has an integrated rotating mechanism, the parts are coated in the bath, circulated and then spun. In the case of a double version of the electroplating drums, the DSC is manufactured as a double trolley.

DSC – the centrifuge that can drive

As a post-treatment system in the electroplating sector, we have had the DSC transport trolley in our modular product range since 2002. It is equipped with an integrated rotating mechanism that enables parts to be coated in a centrifuge basket in the bath, circulated and then spun off over the bath. The maximum speed is 300 rpm with a basket diameter of 900 mm, which is sufficient to transfer the goods to the next treatment bath without dripping. Individual treatment baths can also be placed in interchangeable containers in the system. This means that the customer can exchange media via the containers at short notice and without any conversion work. The smaller volume of the interchangeable containers means that the chemical elements used remain comparatively low.

Passivation process for top coats

Outsourcing the passivation process from the electroplating shop to the centrifuge post-treatment system makes sense, not least because of the additional surface sealing with TopCoats that is required.

In order to achieve comparable corrosion protection properties with the Cr6-free passivations as with those containing Cr6, the use of additional sealants is necessary.

TopCoat coating

Processing such media in the electroplating drum is extremely problematic, as the product carrier has to be cleaned again after treatment. Furthermore, spinning in the electroplating drum is not possible, meaning that a homogeneous surface cannot be produced. For this reason, TopCoat coating and drying is outsourced to the centrifuge post-treatment systems anyway. The problem here is the transfer process of the still wet, passivated product from the electroplating shop to the centrifuge basket. The sensitive surface is damaged in the process.

WMV offers optimal solutions for these problems

When using the WMV system, the goods are transferred from the electroplating shop to the centrifuge basket immediately after the electroplating process. Further treatment processes, such as passivation with the necessary rinsing processes, TopCoat coating and drying, can then take place without any further transfer processes.

Practical and time-saving: After emptying the centrifuge basket, it is washed in an integrated cleaning station and is ready for reloading.

Functional principle

01
Diving

Immerse the basket while turning it slowly.

02
Circulate

Incline the basket to circulate the fabric in the drum.

03
Skidding

Centrifuging with the drum in a straight position to remove excess coating material.

Steps 1 to 3 can be repeated as often as required. The direction of rotation, the drum speed (max. 150 rpm) and the swivel angle can also be adapted to the product to be coated.

The swivel-mounted drip tray prevents liquids from being carried over as far as possible. In addition to processing drum goods, it is also possible to coat rack goods in the DSC.

DSC as a double carriage

With a double version of the electroplating drums, the dip spin is also produced as a double trolley. In this case, the product is transferred from the two halves of the electroplating drum into one drum each of the WMV system and both are fed through the system at the same time.

The Dip Spin coating system can be integrated into the WMV Apparatebau modular system, i.e. existing systems can also be easily retrofitted.

Available original spare parts and our 24/7 support protect your investment.

Questions & Answers

How many top coats can be applied in one DSC system?

Countless top coats can be applied in a DSC system. DSC systems are configured individually according to requirements and set up with as many containers as the coating process of the goods requires.

What is a dip spin process?

The Dip Spin process is a dip-spin process for the uniform coating of components and bulk material in microscopic areas.

What is a dip spin conveyor?

A dip spin conveyor is a transport trolley in a coating system that is designed as a centrifuge. The highly efficient Dip Spin Conveyor is as intelligent as it is flexible: it selects the most suitable container from a variety of containers, moves to it, dips the material in, spins it off and moves the basket directly to the drying or dumping station without delay.
