Compact Dual-Station Laboratory Spin Coater for Pulp Molded
Prototype Development
Composition of Production Line
Product Description
The Compact Dual-Station Laboratory Spin Coater is a
space-efficient, user-friendly benchtop coating system designed
specifically for research laboratories, university pulp molding
programs, product development centers, and small-scale prototype
shops. Unlike larger industrial units, this compact system
prioritizes rapid prototyping and iterative experimentation, enabling fast sample-to-sample optimization of new coating
formulations for molded pulp food containers, protective packaging,
electronics inserts, and compostable tableware prototypes.
The dual-station design, controlled through a single intuitive
touchscreen, allows operators to load two samples and run them
sequentially or simultaneously, significantly accelerating the
R&D cycle compared to single-station machines. Each spin head
can be programmed independently—supporting different substrates,
coating types, or parameters within the same run—while the compact
footprint occupies minimal laboratory bench space-1.
This system is specifically engineered to address the unique
challenges of pulp molded substrate coating R&D—products that are porous, three-dimensional, and often irregular
in shape. The customizable fixturing options ensure stable sample
holding without damage, while the adjustable spin speed and
acceleration profiles accommodate a wide range of coating
viscosities, from low-viscosity water-based barriers to
higher-viscosity bio-polymers. Integrated data logging captures all
process parameters, ensuring each experiment is fully documented
and repeatable-10.
The straightforward operation, combined with flexible recipe
storage, makes this system equally suitable for student
researchers, experienced coating chemists, and manufacturing
engineers. Its simple clean-up and maintenance design also makes it
ideal for multi-user institutional laboratory settings, where ease
of use and reliability across a variety of coatings and substrate
types is paramount.

Features
Compact Benchtop Footprint: Small size (approx. 500 × 450 × 450 mm) occupies minimal
laboratory bench space, ideal for shared facilities and teaching
labs where space is at a premium.
Dual-Station Efficiency: Two independently programmable spin heads to process two samples
simultaneously (parallel) or staggered (alternating) for up to
twice the throughput of single-station equivalents—accelerating
R&D timelines.
Intuitive Touchscreen Control: Single 7-inch color HMI controls both stations with
straightforward, walk‑up‑and‑operate UI pre‑loaded with standard
pulp molding coating recipes, reducing training time and setup
errors.
Programmable Recipes per Station: 5 programmable spin stages per station with speed, acceleration,
and duration control—easily saved, recalled, and edited. Different
recipes can run simultaneously on each station.
Customizable Fixture Compatibility: Vacuum chucks and custom fixtures accommodate a wide range of 3D
pulp molded shapes, including those with curved surfaces, deep
recesses, and asymmetric outlines, ensuring secure sample holding
without damage.
Visible Spin Process: Transparent acrylic chambers allow direct observation of coating
behavior during spin-up, without opening the lid—critical for
diagnosing edge effects, spiral patterns, and droplet ejection
during parameter development.
Solvent Safety & Cleanup: Built-in exhaust ports connect to facility fume extraction;
removable collection bowls and solvent-resistant chamber design
simplify cleaning between coating material changes.

FAQ
Q: What types of 3D-shaped pulp molded products can be coated on this
system?
A: With custom fixtures, the system can accommodate a wide range of
3D shapes including bowls, plates, trays, cups, food containers,
electronics packaging inserts, and specialty molded products. The
key is the sample fixture, which we can design specifically for
your product geometry, including those with curved surfaces, deep
recesses, or asymmetric profiles. Typical size limit approximately
100 mm footprint with 50 mm height.
Q: Can this system handle both thin-film coatings and thicker barrier
coatings?
A: Yes. The broad speed range (300–8,000 RPM, extendable to 10,000
RPM) combined with programmable acceleration profiles allows
processing of low-viscosity solutions for thin films (e.g.,
PFAS-free oil barriers,coatings) as well as higher-viscosity
dispersions for thicker barrier layers (e.g., PLA, PHA) by using
lower speeds and longer dispense/dwell times. Dispense volume and
spin time are fully adjustable.
Q: Is the system easy to clean between different coating types?
A: Yes. The removable collection bowls are interchangeable, and each
chamber can be cleaned independently. The chamber interiors and
spin heads are designed to be wiped down quickly without
disassembly. We also provide a detailed cleaning protocol for
common coating chemistries to avoid cross-contamination.
Q: Does the system require a dedicated compressed air supply?
A: No. The system operates on standard AC power only, with an
integrated vacuum pump for substrate holding and manual dispense
(or optional automated syringe pump). No compressed air is
required.
Q: What safety features are included?
A: Each station is equipped with a lid interlock that stops the spin
motor when the lid is opened, preventing exposure to rotating parts
and splashing hazards. The system also includes emergency stop
buttons per station, overcurrent protection, and a safety interlock
for vacuum loss. For solvent safety, the exhaust ports connect to
facility fume extraction. All electrical components are
CE-certified.
Q: Can this system be used for student training and multi-user lab
environments?
A: Yes. The intuitive touchscreen interface, lockable recipe storage,
and straightforward cleaning protocol make it ideal for multi-user
academic and industrial lab environments. Different researcher
profiles and password protection are available to prevent
unintended parameter changes across projects.
