How to Choose a Softgel Encapsulation Machine for Your Factory

The best softgel machine is not the model with the highest published speed. It is the machine that can produce your formulation, dose, capsule format, and annual volume at a stable quality level within the limits of your factory.

Before comparing quotations, review the available softgel machine models against a written user requirement. This prevents the purchasing decision from being reduced to price or theoretical capsules per hour.

This guide follows the buyer's real decision path: product definition, capacity calculation, dosing, tooling, formulation compatibility, supporting equipment, utilities, compliance, service, and total ownership cost.

Define the Product Before Selecting the Machine

Begin with the capsule, not the equipment catalog. Document:

• Intended application and market
• Shell material
• Fill type
• Single-capsule dose
• Capsule shape and dimensions
• Active-ingredient sensitivity
• Expected batch size
• Cleaning and cross-contamination requirements

An oil solution, a high-solids suspension, and a heat-sensitive semi-solid do not create the same dosing and handling requirements. Similarly, animal-gelatin and plant-based shell systems may need different operating ranges and tooling details.

Calculate the Required Hourly Output

Use annual demand and effective production time instead of selecting a machine by its maximum catalog speed.

Required hourly output = Annual demand ÷ Planned production days ÷ Effective operating hours ÷ Expected yield

Example:

• Annual demand: 120,000,000 saleable capsules
• Planned production: 250 days
• Scheduled time: 16 hours per day
• Effective operating factor after changeover, cleaning, maintenance, and stops: 75%
• Expected yield: 95%

Effective operating hours are 250 x 16 x 0.75 = 3,000 hours.

Required gross output is approximately:

120,000,000 ÷ 3,000 ÷ 0.95 = 42,106 capsules per hour.

The calculation should then include:

• Startup and shutdown losses
• Product changeovers
• Cleaning time
• Preventive maintenance
• Unplanned downtime allowance
• Seasonal peaks
• Planned business growth

Do not simply add an arbitrary percentage. Build a production calendar that shows when the machine is genuinely available.

Select the Appropriate Machine Scale

Laboratory and development projects

Prioritize low material consumption, controllability, cleanability, data collection, and a credible scale-up path.

Small-batch commercial production

Prioritize changeover time, flexible tooling, simple cleaning, operator access, and efficient production of varied products.

Medium-volume production

Balance output with flexibility. Review the number of plungers, tooling width, automation, drying capacity, and expected campaign length.

High-volume production

Prioritize repeatable continuous operation, stable material supply, preventive maintenance access, redundancy strategy, and the ability of dryers and inspection equipment to accept the output.

Match Capacity to Capsule Size and Tooling

Output depends on more than die-roll speed. Capsule size, shape, pocket arrangement, die width, number of plungers, and usable line speed all influence production.

The URMACHINE parameter table illustrates why the test basis matters:

These are reference outputs for named capsule formats and speeds, not guaranteed stable output for every product.

Ask suppliers to separate:

• Rated machine capability
• Reference output for a sample tool
• Output demonstrated during FAT
• Stable saleable output during an agreed continuous run

Evaluate Dosing Accuracy and Material Loss

Filling performance matters for dose consistency and cost. It is especially important when the fill contains expensive oils or high-value active ingredients.

The supplied URMACHINE model table lists a dosing specification of 1.5 ml, ±1.5% for the identified models. During evaluation, confirm:

• Whether the value applies to your dose range and fill material
• How accuracy is calculated
• Sample size and sampling interval
• Whether results are reported as individual variation or an average
• Performance at startup, stable speed, and restart
• The amount of material remaining in tanks, lines, and pumps

A machine with a lower purchase price can be more expensive if it consistently overfills or produces a higher reject rate.

Check Tooling and Changeover Flexibility

Tooling determines capsule shape, size, and pocket layout. Review:

• Supported die-roll dimensions
• Available oval, oblong, round, and special shapes
• Minimum and maximum practical dose
• Die and wedge changeover procedure
• Time required for cleaning and setup
• Number of operators required
• Tool storage and protection
• Delivery time for new tooling
• Inspection and refurbishment service

If the factory will produce many small campaigns, changeover efficiency can create more annual capacity than a modest increase in maximum running speed.

Confirm Fill and Shell Compatibility

Oil solutions

Review pumpability, temperature sensitivity, oxidation control, and material compatibility.

Suspensions

Confirm particle-size limits, mixing requirements, service-tank agitation, transfer behavior, and resistance to sedimentation.

Semi-solid fills

Evaluate the temperature-viscosity relationship and whether the fill remains stable through the pump and wedge.

Plant-based shells

Ask for evidence using the intended shell system. Confirm the available temperature-control range, ribbon formation, tooling design, sealing behavior, and drying process.

Compatibility should be demonstrated with a meaningful trial, not assumed from a general statement.

Compare Automation and Control Features

Useful controls may include:

• Touchscreen or PLC interface
• Coordinated die and pump control
• Gelatin-level management
• Temperature monitoring
• Alarm history
• Recipe storage
• User access levels
• Production-data recording
• Remote support capability

Automation should make the process more repeatable and diagnosable. It should not hide poor mechanical access or make basic maintenance dependent on unavailable specialist support.

The supplied models use different control approaches, including standard control, touchscreen systems, and Siemens PLC platforms. Buyers should review these differences together with service capability and factory standards.

Identify All Supporting Equipment

A standalone encapsulator cannot complete the process. A project may require:

• Gelatin melting and service tanks
• Fill mixing and service tanks
• Homogenization or milling
• Transfer and filtration systems
• Tumble dryers
• Trays, racks, drying rooms, or drying tunnels
• Inspection and polishing equipment
• Packaging equipment
• Chilled water and compressed air
• HVAC and dehumidification

Ask every supplier quotation to state what is included, excluded, or supplied by others.

Check Factory Space and Utilities

Use equipment drawings to plan:

• Installation footprint
• Operating space
• Tool-removal space
• Cleaning and maintenance access
• Material and personnel flow
• Drainage
• Electrical supply
• Chilled-water capacity
• Compressed-air requirements
• HVAC and humidity control
• Floor loading

The supplied URMACHINE model dimensions range from the RGY2-15 at 1,400 x 800 x 1,750 mm to the HTMBRG1316DD at 2,400 x 1,250 x 2,200 mm. These dimensions describe the machines, not the total room area needed for operation and service.

Verify GMP, Safety, and Documentation

Depending on the project and market, request:

• Product-contact material certificates
• Surface-finish information
• Electrical drawings
• Mechanical drawings
• Instrument and calibration lists
• Operating and maintenance manuals
• Cleaning guidance
• Spare-parts lists
• Risk assessment
• FAT protocol
• SAT support
• IQ/OQ documentation or support
• Safety devices and interlock descriptions

The exact package should be stated in the purchase agreement.

Compare Total Cost of Ownership

Total cost includes more than the machine:

TCO = Purchase + Tooling + Utilities + Installation + Qualification + Labor + Consumables + Maintenance + Spare Parts + Downtime + Quality Loss

Compare:

• Material loss during startup and shutdown
• Overfill
• Reject rate
• Changeover labor
• Cleaning time
• Energy and environmental-control demand
• Planned maintenance
• Critical spare-parts inventory
• Remote and onsite service
• Lost output during downtime

Use a common calculation period and production forecast for all suppliers.

Frequently Asked Questions

What is the best softgel encapsulation machine?

There is no universal best machine. The correct choice is the model that matches the product, capacity, quality system, utility limits, maintenance capability, and ownership-cost target.

Should a startup buy a laboratory or commercial machine?

The answer depends on whether the goal is formulation development, pilot batches, or saleable commercial output. Regulatory, drying, inspection, and packaging requirements should be considered before selecting a scale.

How much extra capacity should be reserved?

Reserve capacity should come from a documented production calendar covering changeovers, cleaning, maintenance, expected downtime, yield, peaks, and growth. Avoid an unsupported blanket percentage.

Should I buy a standalone machine or a complete line?

Choose a standalone unit only if compatible preparation, drying, inspection, utilities, and integration capability already exist. Otherwise, a coordinated line may reduce interface risk.

Can one machine produce several softgel sizes?

Yes, if appropriate tooling, dosing components, and process settings are available. Changeover time and validation requirements should be included in the decision.

Select the Machine Around Your Product

Softgel machine selection should convert a product and business plan into measurable equipment requirements. Define the capsule, calculate effective capacity, verify accuracy, examine tooling and compatibility, confirm the complete line, and compare ownership cost.
