2. What Is a DPH 280H Fully Servo Blister Packaging Machine

A DPH 280H Fully Servo Blister Packaging Machine is an automated blister packaging machine used to form cavities from plastic film or cold-form foil, fill those cavities with products, seal them with lidding material, and then cut or punch the finished blister packs into final formats.

The machine is commonly used for:

• tablet blister packaging

• capsule blister packaging

• softgel blister packaging

• medical device blister packaging

• consumer healthcare blister card packaging

• small hardware blister packaging

• diagnostic kit blister packaging

The phrase Fully Servo means the key motion points of the machine are controlled by servo motors rather than depending only on mechanical cams, chains, or simple pneumatic indexing.

The phrase 280H generally indicates a machine platform in the 280 mm class, often associated with:

• wider forming film

• larger forming area

• higher output potential

• broader format flexibility

• better suitability for industrial-scale production

3. Why the DPH 280H Class Matters

The DPH 280H class is important because it typically represents a strong balance between:

• compact enough for practical factory integration

• large enough for medium to high throughput

• flexible enough for multiple blister layouts

• powerful enough for industrial production

Publicly available comparable models in the 270–320 class show that machines in this segment often support 270–320 mm packaging material widths, larger forming areas, and significantly higher output than entry-level blister machines. For example, published references show DPH-280 platforms with 280 mm PVC and PTP width, 200 × 280 mm forming area, while a 320 class full-servo model lists 320 × 280 mm maximum molding area and a 280/360/380 class line lists 280 × 240 mm on the 280 version.

Why buyers search for the 280 class

Typical reasons include:

• more cavities per index

• better throughput for tablets and capsules

• higher production efficiency

• support for multiple plate sizes

• easier downstream integration with cartoning systems

4. What Fully Servo Means in Blister Packaging

A fully servo blister packaging machine uses servo motors to control the main synchronized motion axes of the packaging process.

Instead of relying primarily on:

• mechanical cam timing

• chain-dominant motion

• fixed-speed mechanical indexing

a DPH 280H Fully Servo Blister Packaging Machine may servo-control:

• web traction and indexing

• feed synchronization

• forming movement or positioning

• sealing registration

• punching timing

• print mark tracking compensation

• waste rewinding synchronization

• optional pick and place modules

Why this matters

Servo systems improve:

• positioning accuracy

• repeatability

• motion smoothness

• product changeover efficiency

• fault diagnostics

• line speed stability

• reduced mechanical shock

5. Main Working Principle

The DPH 280H Fully Servo Blister Packaging Machine typically follows a structured multi-station workflow.

Step-by-step operating sequence

1. Base film unwinding
   The machine unwinds the forming material, such as PVC, PVC/PVDC, ACLAR laminate, or cold-form foil.

2. Web guiding and tension control
   Guide rollers and traction systems maintain stable alignment.

3. Preheating
   In thermoforming mode, plastic film is heated before cavity formation.

4. Forming
   Cavities are formed by:

• pressure forming

• vacuum forming

• pressure plus vacuum assist

• cold-form stamping for alu-alu structures

5. Product feeding
   Products are placed into the formed pockets using a dedicated feeder.

6. Inspection (optional)
   Sensors or vision systems check for:

• missing product

• broken tablets

• empty pockets

• misfeeds

7. Lidding foil unwinding
   Heat-sealable aluminum foil or other lidding stock is aligned over the formed web.

8. Heat sealing
   The lidding material is sealed to the blister web under controlled heat and pressure.

9. Coding or embossing
   Batch code, lot code, or expiry information may be added.

10. Perforation or scoring
    Tear lines or separation marks can be introduced.

11. Punching or cutting
    Final blister cards are cut to size.

12. Scrap rewinding
    Waste trim is collected.

13. Finished blister discharge
    Packs are transferred to collection or downstream cartoning.

6. Machine Structure and Core Stations

A typical DPH 280H Fully Servo Blister Packaging Machine contains the following functional stations.

7. Key Features of a DPH 280H Fully Servo Blister Packaging Machine

A typical DPH 280H Fully Servo Blister Packaging Machine is expected to include:

• full servo drive system

• PLC control platform

• touchscreen HMI

• photoelectric registration tracking

• adjustable stroke length

8. Material Compatibility

Material compatibility is one of the most important selection criteria.

Public blister machine references in comparable classes commonly list compatibility with PVC, PVC/PVDC, PVC/AL/OPA, ACLAR, and heat-sealable aluminum foil, while some 270–280 class and larger lines also list cold formed aluminum foil or tropical foil support.

Common Forming Materials

• PVC rigid film

• PVC/PVDC laminate

• PVC/PE/PVDC laminate

• PVC/AL/OPA laminate

• ACLAR laminate

• PP film in selected designs

• Cold-form aluminum foil (Alu-Alu)

Common Lidding Materials

• PTP aluminum foil

• heat-sealable aluminum foil

• PVDC-coated lidding foil

• paper-based lidding laminate

• child-resistant foil

• peelable lidding foil

Typical Material Thickness Ranges

Comparable published machines list PVC ranges such as 0.15–0.45 mm, 0.15–0.50 mm, and PTP foil around 0.02–0.035 mm or 0.02–0.04 mm, which supports these reference ranges.

10. Thermoforming vs Cold Forming

A DPH 280H Fully Servo Blister Packaging Machine may be configured for thermoforming, cold forming, or in some cases both, depending on machine architecture and tooling.

Thermoforming

Thermoforming uses heated plastic film to create blister cavities.

Benefits

• transparent pack

• lower material cost

• strong visual merchandising

• often higher speed than cold forming

• good for OTC and consumer healthcare

Typical materials

• PVC

• PVC/PVDC

• ACLAR laminate

Cold Forming

Cold forming uses a laminated aluminum structure that is mechanically formed into cavities.

Benefits

• excellent moisture barrier

• excellent oxygen barrier

• full light protection

• ideal for highly sensitive pharmaceutical products

Trade-offs

• slower cycle potential

• higher material cost

• opaque blister

• larger cavity pitch often required
