TRANSFORMER CORE & COMPONENT MANUFACTURING
From Precision-Cut Laminations to Assembled Components
MOOPEC supports transformer-component manufacturing from precision-cut CRGO laminations to assembled laminated cores, wound-core configurations, semi-finished active parts and custom HV/LV windings.
Manufacturing Support for Your Required Delivery Stage
Customers do not always require the same delivery stage. Some projects need prepared laminations, others need an assembled core, a wound-core configuration, a semi-finished active part or a winding package. MOOPEC reviews the drawing, material, transformer type, voltage class, capacity, dimensions, target performance, inspection plan and destination before defining the supply scope.
Transformer Core Manufacturing Flow
| Step | Manufacturing Stage | Process Description |
|---|---|---|
| 01 | Precision blanking | Prepare CRGO laminations to the customer drawing and cutting plan. |
| 02 | Lamination stacking | Build the required core geometry in the specified stacking sequence. |
| 03 | Alignment and fit-up | Control lamination alignment, joint fit and core dimensions before final assembly. |
| 04 | Clamping and assembly | Secure the core according to the specified construction and delivery requirement. |
| 05 | Dimensional inspection | Check critical dimensions and assembly condition before release. |

Wound-Core Options
Continuous wound silicon steel core options are available for customer-specific transformer designs. The appropriate construction is selected according to the drawing, dimensions, material, winding arrangement, required delivery stage and application requirements.
Core option
UNI Core
Custom UNI Core configuration manufactured to the customer drawing and project requirements.
RACE Core
RACE Core option for customer-defined dimensions, material and application requirements.
Octagonal / 3D Wound Core
Octagonal or three-dimensional wound-core configuration for custom transformer designs.
Deep Processing
Extended Manufacturing Scope
01
Semi-Finished Active Parts
For projects that require fewer production interfaces, MOOPEC can coordinate core processing, winding integration, active-part assembly and inspection within an agreed semi-finished transformer scope. The quotation should define the included components, customer-supplied information, assembly stage, inspection points, documentation and packing method.
02
Custom HV & LV Windings
MOOPEC produces custom high-voltage and low-voltage windings according to customer drawings and order specifications. Enquiries should include the transformer type, voltage class, rated capacity, winding dimensions, conductor and insulation requirements, terminal arrangement, quantity and inspection plan.
03
Inspection and Traceability
Inspection is defined for each product and delivery stage. It may include incoming-material verification, dimensional measurement, mechanical-property testing, in-process checks, assembly inspection, data logging, production records and batch traceability.
Third-party or SGS reports can be included in the order with the test items, sample plan, acceptance criteria and report format clearly stated.
04
Packaging and Export Preparation
Packaging is selected according to the product, handling method, transport route and storage requirement. Master coils may be prepared using horizontal or vertical packing with protective materials, edge protection, strapping and a suitable base. Finished cores, wound cores, windings and semi-finished assemblies require product-specific protection and secure export packing.
