Planning Multi-Category Appliance Manufacturing in Southeast Asia
Adding refrigerators to a washing machine manufacturing operation changes more than the assembly layout. It introduces new component dimensions, forming requirements, tooling and production schedules. Before ordering equipment, manufacturers need to establish which resources can be shared, which processes need dedicated machinery, and how both will meet the required output.
Midea’s manufacturing expansion in Indonesia provides a timely example of this broader planning challenge. In its September 9, 2026 announcement, the company described local operations covering air conditioners, refrigerators and washing machines. Its washing machine facility exceeds 17,000 square meters, with twin-tub production and plans to introduce top-loading models.
Midea’s separate announcement about its Karawang refrigerator factory describes a site exceeding 150,000 square meters, with a designed annual capacity of more than two million units. The planned range includes side-by-side, double-door and single-door refrigerators, alongside chest freezers.
For companies planning appliance manufacturing in Southeast Asia, the equipment decisions depend on their own product range, existing assets and local operating conditions. The following guide examines those decisions, focusing on sheet-metal components, stamping equipment and assembly processes.
1. Decide Which Processes Can Be Shared
Material preparation, selected stamping operations, warehousing and factory utilities are candidates for sharing. Drum forming, refrigerator foaming and other product-specific operations generally require dedicated process arrangements. Whether sharing works depends on material compatibility, equipment capacity and production scheduling.
| Manufacturing resource | Potential for sharing | Main conditions to check |
| Sheet-metal preparation | Possible across compatible materials and sizes | Coil or blank dimensions, thickness range, surface protection |
| Stamping presses | Possible with suitable tooling and available capacity | Forming requirements, die fit, handling clearance, scheduling |
| Warehousing and logistics | Often suitable for shared infrastructure | Part identification, storage protection, delivery frequency |
| Inspection resources | Some equipment and data systems may be shared | Measuring range, accuracy, dedicated gauges and test methods |
| Drum forming and joining | Usually configured around a defined component family | Drum geometry, material, joint design, assembly requirements |
| Refrigerator foaming | Requires a dedicated process arrangement | Cabinet design, fixtures and process controls |
2. Check Whether Existing Presses Can Support New Parts
An existing press can be considered for another appliance component only when both its technical suitability and its available production time have been established. Nominal tonnage alone is insufficient.
| Item to check | What the assessment should establish |
| Forming load and press capacity | Whether the press can provide the required force at the relevant working position |
| Available energy and operating speed | Whether the forming process can run at the proposed production rate |
| Bolster and slide dimensions | Whether the die can be properly supported, mounted and clamped |
| Stroke and die height range | Whether forming, opening and part removal can be accommodated |
| Die dimensions and weight | Whether installation and handling remain within equipment limits |
| Feeding arrangement | Whether coils or blanks can be supplied accurately without damaging the material |
| Transfer and unloading clearance | Whether the workpiece and handling devices have sufficient space |
| Controls and machine interfaces | Whether the press, feeder and transfer equipment can operate together |
| Equipment condition | Whether wear, maintenance requirements or control limitations affect the application |
3. Plan Stamping Dies Around Assembly and Model Changes
Appliance stamping dies should be specified against the finished component and its downstream assembly requirements. Part geometry, material, production volume and available presses then guide the choice of progressive, stage or transfer tooling.
- Material grade, thickness and surface condition.
- Critical dimensions and their relationship to mating components.
- Forming sequence and proposed press arrangement.
- Inspection methods and acceptance criteria.
- Expected production volume and model range.
- Tool maintenance and replacement wear components.
IDO’s sheet-metal stamping dies include applications for washing machine drums, cabinets and panels, as well as other appliance components.
IDO’s front-loading washing machine drum assembly line with lock-seaming is one relevant equipment category.
4. Match Automation to Volume, Product Mix and Maintenance Capability
| Planning factor | Why it affects the automation decision |
| Required output and shift pattern | Establishes the production rate and available operating time |
| Number of models and batch sizes | Determines how often fixtures, programs or handling devices must change |
| Part dimensions and surface requirements | Influences gripping, positioning and protection methods |
| Downtime and recovery arrangements | Determines how interruptions affect the rest of the line |
| Maintenance skills and spare parts | Affects the factory’s ability to sustain operation |
| Labor and operating costs |
Supports a location-specific investment calculation |
5. Define Supplier Responsibilities Before Installation
Before placing orders, establish who is responsible for:
- Site preparation, foundations and utilities.
- Equipment installation and connections between machines.
- Controls integration and operating documentation.
- Tool trials and component quality verification.
- Operator and maintenance training.
- Spare parts and technical support after handover.
For a project involving refrigerator production equipment, define the exact process scope in the quotation.
6. Prepare an Expansion Brief Before Requesting Quotations
| Information to prepare | Details to include |
| Product range | Appliance categories, initial models and planned additions |
| Production targets | Annual demand, peak requirements, shifts and ramp-up schedule |
| In-house manufacturing scope | Components and operations to be retained internally |
| Component information | Drawings, material grades, thicknesses, tolerances and samples |
| Existing machinery | Press specifications, condition, current utilization |
| Factory layout | Available space, handling routes, storage areas |
| Model changeovers | Batch sizes, expected frequency and required adjustments |
