What are WHIMS coils?
WHIMS stands for Wet High-Intensity Magnetic Separator.
A WHIMS coil is an electrical coil used inside wet high-intensity magnetic separation equipment. Its role is to help generate the magnetic field used to separate weakly magnetic material from slurry during mineral processing.
In plain English, the coil helps the separator do the work of separating material. If the coil is not performing correctly, the separator cannot perform as intended.
A WHIMS coil is therefore not a basic spare part. It is a key component in the separation process. It must be manufactured correctly, insulated properly, protected for the operating environment, and tested before it is returned to service or supplied as a replacement.
What does a WHIMS coil do in a mineral processing plant?
A WHIMS coil supports the magnetic field inside a Wet High-Intensity Magnetic Separator. This magnetic field is used to separate weakly magnetic particles from non-magnetic particles in a wet slurry. This matters because mineral processing plants rely on controlled separation. The coil must support consistent operation, often in harsh plant conditions where heat, water, vibration, electrical load, and continuous production demands are part of normal operation.
If the coil fails, the plant may face:
- Unplanned downtime.
- Reduced separator availability.
- Maintenance pressure.
- Delayed production.
- Emergency procurement.
- Longer lead times if a replacement is not available.
- Uncertainty around whether the failed coil can be repaired.
This is why WHIMS coil manufacturing in Cape Town should be handled by a manufacturer with direct experience in industrial coil work and WHIMS coil applications. Like CAW.

Why WHIMS coil manufacturing quality matters
WHIMS coils work in demanding conditions. They are exposed to electrical load, heat, moisture, mechanical handling, vibration, and continuous plant use. A coil may look correct from the outside, but still fail if the winding, insulation, materials, protection, or testing are not right. Quality matters because a WHIMS coil must perform electrically, mechanically, and physically in the separator.
A well-manufactured WHIMS coil must:
- Fit the equipment correctly.
- Meet the electrical requirement of the application.
- Be wound accurately.
- Be insulated properly.
- Be protected for the operating environment.
- Withstand heat and load during operation.
- Be tested before supply.
- Be supported by a controlled manufacturing process.
In a production environment, coil reliability directly affects plant availability.
A poor-quality coil can create expensive problems. The plant may lose production time, maintenance teams may have to repeat work, procurement may need to source another replacement, and the separator may remain unavailable for longer than planned.
What makes WHIMS coils technically demanding?
WHIMS coils are technically demanding because they need to operate reliably in equipment that works under wet, high-intensity, heavy-duty conditions. Here are the main technical challenges.
Electrical load
The coil must support the magnetic field required by the separator. The conductor, winding, insulation, and construction must be suitable for the electrical demand of the application.
Heat
Coils generate heat during operation. The coil must be manufactured with this in mind. Poor insulation, incorrect materials, weak construction, or manufacturing faults can increase the risk of heat-related failure.
Moisture and contamination
WHIMS equipment operates in wet mineral processing environments. The coil needs suitable protection and insulation integrity to reduce the risk of moisture-related damage.
Mechanical stress
Coils are handled, transported, installed, and operated in heavy industrial environments. The coil must be manufactured and protected with the working environment in mind.
Fitment
A WHIMS coil must fit the separator correctly. Dimensional accuracy matters. If a coil is not manufactured to the correct physical requirements, installation and operation can become difficult or unreliable.
Testing
A coil should not be supplied on appearance alone. Testing helps confirm whether the coil is suitable before it is installed or returned to service.
What types of WHIMS coils do we manufacture in Cape Town?
We manufacture shim and round wire WHIMS coils.
This is important because different WHIMS coil applications may require different manufacturing approaches. The correct solution depends on the existing coil design, the equipment requirements, the available specifications, and the operating conditions.
We can work from the information you have available. This may include drawings, dimensions, photos, existing coil details, electrical specifications, or the failed unit itself. If you do not have complete documentation, you can still enquire. We can guide the next step based on what is available.
What goes into WHIMS coil manufacturing?
WHIMS coil manufacturing is a controlled process. It is not simply a matter of winding conductor into shape. The coil must be built for a specific application, separator, electrical requirement, and working environment.
The manufacturing process should consider the following.
1. Understanding the requirement
Before manufacturing starts, the coil requirement must be understood. This may include:
- The type of WHIMS equipment.
- The dimensions of the coil.
- The electrical specification.
- The existing coil design.
- The conductor type.
- The insulation requirements.
- The operating environment.
- The urgency of the replacement.
- Whether the coil must be manufactured, repaired, or refurbished.
Where a coil has failed, fault finding is important. It helps identify what went wrong and whether repair, refurbishment, or replacement is the most practical option.
2. Working from available information
In some cases, a plant has full drawings and specifications. In other cases, the information is incomplete, especially where equipment is older or where the original coil has been in service for many years.
A practical WHIMS coil manufacturer must be able to work with the information available and advise what else is needed. This may include measurements, photos, technical checks, or inspection of the failed coil.
3. Material and component planning
The materials and components used in WHIMS coil manufacturing affect the final quality of the coil. The conductor, insulation, protection, and supporting components must suit the application.
We hold stock of materials and components to support quicker turnaround times. This helps when a plant cannot afford unnecessary delays caused by material availability.
4. Controlled winding
Winding accuracy is central to coil quality. The winding must be controlled, consistent, and suitable for the coil design. Our designated coil winding department supports this process. It means the work is handled by a focused department with the equipment and experience needed for coil manufacturing.
5. Insulation and protection
Insulation helps prevent electrical failure. In WHIMS coil manufacturing, insulation must be selected and applied with the operating conditions in mind. This is especially important because WHIMS coils operate in wet, industrial environments. Poor insulation can lead to premature failure, safety concerns, and repeat downtime. Protection is also important. The coil must be prepared for handling, installation, heat, moisture exposure, and plant conditions.
6. Quality control
A controlled manufacturing process helps reduce defects and improves consistency. We follow a QCP to support a quality product. A quality control plan gives structure to the manufacturing process and helps ensure the correct checks are carried out.
7. Testing
Testing is essential before the coil is supplied or returned to service. It helps identify faults and gives the plant more confidence before installation. We use winding and testing equipment as part of our WHIMS coil manufacturing and refurbishment capability.
8. Reporting
When a coil has failed or has been refurbished, reporting gives your team better visibility. It helps maintenance, engineering, and procurement teams understand what was found and what work was done.
We provide photographic reporting and fault finding. This supports clearer decision-making and gives your team a better record of the coil condition and work completed.
Manufactured, refurbished, repaired or replaced WHIMS coils
When a WHIMS coil fails, the first question is usually practical: can it be repaired, should it be refurbished, or does it need to be replaced? The correct answer depends on the condition of the coil.
WHIMS coil repair
Repair may be suitable when the damage is limited and the coil can be restored to a reliable working condition.
WHIMS coil repairs in Cape Town may be considered when:
- The fault is clearly identified.
- The damage is localised.
- The conductor is still suitable.
- The insulation can be restored safely.
- The mechanical condition is acceptable.
- The repair makes sense based on cost, time, and risk.
WHIMS coil refurbishment in Cape Town
Refurbishment may be suitable when the coil needs more extensive work but does not require complete replacement.
Refurbishment may be considered when:
- The coil has aged but remains recoverable.
- Insulation or protection needs attention.
- The plant wants to extend the usable life of the coil.
- The coil is still mechanically suitable.
- Testing and inspection support the decision.
WHIMS coil replacement
Replacement may be the right decision when repair or refurbishment is not practical, safe, or reliable.
Replacement may be considered when:
- The coil has severe electrical damage.
- The coil has severe mechanical damage.
- Insulation failure is widespread.
- The coil has overheated badly.
- The coil has failed more than once.
- The risk of returning it to service is too high.
- The plant needs a more reliable long-term solution.
New WHIMS coil manufacturing in Cape Town
A new manufactured WHIMS coil may be required when the original coil cannot be restored, when a spare is needed, when lead times are too long, or when the plant wants a locally manufactured replacement. A manufactured coil should be based on the correct technical information, controlled winding, suitable insulation, proper protection, and testing before supply.
How our WHIMS coil solutions help your plant
Our WHIMS coil manufacturing and refurbishment capability is designed to support the real problems plants face.
When your separator is down
A failed coil can stop or limit production. We help you assess the failed coil, identify the practical route forward, and support repair, refurbishment, or replacement where suitable.
When lead times are a problem
Long lead times can put pressure on maintenance and production schedules. Our stock holding of materials and components supports quicker turnaround times where possible.
When you do not know whether to repair or replace
A failed coil is not always an automatic replacement. It needs to be assessed. Fault finding and photographic reporting help you make a more informed decision.
When drawings or specifications are incomplete
Older equipment does not always come with complete documentation. We can work with available information and guide you on what is needed to assess the coil requirement.
When procurement needs a reliable local supplier
Procurement teams need more than a quote. They need a supplier that understands the requirement, communicates clearly, and can support the plant with practical manufacturing and refurbishment capability.
When maintenance needs a technical answer
Maintenance teams need to know what failed, what can be done, and what the risk is. Fault finding, inspection, and reporting help support that decision.
