Production Flowchart

The complete paper forming solution includes PART I laminating & die cutting, PART II forming, and PART II sealing. Multi-layer paper is coated, hot-pressed, die-cut, formed, sealed, dried and finally collected as finished paper cutlery.

PART I

Laminating & Die Cutting Section

Multiple paper rolls are coated with environmental water-based glue or plastic-free coating paper, then hot-pressed and laminated before die cutting. The die cutting mold is replaceable, and semi-finished blanks are discharged by conveyor.

STEP 01

Single Layer Gluing

Each paper roll is coated with environmental glue or plastic-free coating.

STEP 02

Hot Press Laminating

Multiple paper layers are hot-pressed into one high-stiffness composite sheet.

STEP 03

Die Cutting

The replaceable die cutting mold cuts blanks for knife, fork or spoon forming.

STEP 04

Stacking

Die-cut semi-finished blanks are stacked and prepared for the next process.

STEP 05

Waste Rewinding

Remaining material is rewound after die cutting for cleaner production.

PART II-A

Forming Section

The die-cut semi-finished blanks are placed into the jig. The manipulator picks and transfers them to the forming station. The forming mold is replaceable, and the formed products are sucked by the manipulator and output by conveyor.

STEP 06

Temperature Module Setting

Set temperature modules for stable hot forming preparation.

STEP 07

Forming Mold Placement

Place the replaceable forming mold based on target product shape.

STEP 08

Working Parameter Setting

Set working parameters before automatic forming and transfer.

STEP 09

Robotic Suction Transfer

The manipulator places the semi-finished blank into the forming mold.

PART II-B

Sealing Section

The formed semi-finished products are placed in the jig. The manipulator picks and inserts them into the rail-type clamp device. The chain drives products through hot pressing, optional gluing, drying and final output for collection and packing.

STEP 10

Hot Press Sealing

The formed product is hot-pressed for structure fixing and sealing.

STEP 11

Gluing Optional

Optional gluing is available according to product structure requirements.

STEP 12

Drying

Products pass through drying by chain transmission before final output.

STEP 13

Final Product Collection

Finished paper cutlery is output for collection and packing.

Application Scenarios

Packaging Components

Formed and sealed paper inserts for box and carton packaging.

Molded Paper Products

Used after lamination & die cutting to shape and seal molded paper pieces.

Composite Paper Structures

Applications where sealing and forming enhance structural performance.

Why OYANG Machines Last Longer & Run Faster

Every OYANG machine is built on three manufacturing pillars that competitors simply cannot match — delivering measurably better stability, precision and service life.

World-Class CNC Precision Machining

OYANG is the only packaging machine manufacturer in China to invest $30 million in a world-class CNC machining center — equipped with Japanese MAZAK flexible production lines for 24/7 automated processing and Okuma systems. Every wall panel, flange and structural component is machined to micron-level tolerances, ensuring long-term machine stability and consistent quality.

Key Benefits:

MAZAK flexible lines run 24/7, reducing human error in core part production

Okuma systems ensure sub-micron dimensional accuracy on flanges and wall panels

Consistent part quality across every machine — no batch variation

Longer component lifespan, with annual spare parts cost of around $400 USD compared with an industry average of $1,500 USD

Full Servo-Driven Motion Control

Unlike conventional machines that rely on mechanical cams and pneumatic timing, OYANG machines use full servo motor control across all critical axes. Each motion is independently programmable, enabling instant parameter adjustment, faster changeovers and real-time feedback correction.

Key Benefits:

Independent servo axes eliminate mechanical wear from cam-driven systems

Bag size changeover can be completed through the touchscreen, with no manual tool adjustment

Real-time closed-loop feedback maintains ±0.5 mm positional accuracy

Lower energy consumption and reduced heat generation compared with hydraulic or cam systems

Monolithic Cast-Iron Core Structure

While many manufacturers weld or bolt together multiple steel plates, OYANG uses one-piece integral casting for all core structural components. This eliminates joint stress points, dramatically improves rigidity and ensures the machine frame remains stable even after years of high-speed operation.

Key Benefits:

No weld joints — eliminating the leading cause of long-term frame deformation

Superior vibration damping helps maintain stable high-speed output at 90–100 pcs/min

Maintains geometric precision over 10+ years of continuous production

Every new product passes 10,000 rigorous tests before market release

OYANG Machines vs. Typical Industry Standard

OYANG Machines

MAZAK & Okuma CNC — micron-level part accuracy

Full servo control — instant parameter changeover

Integral cast frame — zero joint stress and 10+ year lifespan

Annual spare parts cost: around $400 USD

Typical Industry Standard

General CNC — variable tolerances between batches

Cam / pneumatic driven — manual retooling required

Welded steel frame — joint fatigue after 2–3 years

Annual spare parts cost: around $1,500 USD
