Compact Dual-Station Laboratory Spin Coater for Pulp Molded Prototype Development

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.

Technical Parameters

Application

This compact dual-station spin coater is ideally suited for pulp molding R&D, pilot line, and small-scale lab environments:

• Prototype Sample Preparation: Coating of prototype and pilot-scale molded pulp products for customer presentation, regulatory testing (e.g., compostability certification), or performance validation prior to committing to full-scale manufacture.

• Process Parameter Optimization: Quickly determine the optimal spin speed/duration combinations for new coating materials or complex part geometries before scaling to production.

• Small-Batch Custom Coating: Producing limited runs of coated specialty products or artisanal pulp goods where production volumes do not justify full-scale automated lines.

• Chamber Material: Choice of transparent acrylic for process visibility (preferred for teaching and troubleshooting), stainless steel for chemical resistance and durability, or PTFE-lined for aggressive solvents.

• Hot Plate Integration: Pre-bake or post-bake hot plate module for drying or curing coatings (temperature range RT–150°C) built directly into one or both stations.

• Nitrogen Inert Capability: Inert gas purge port for oxidation-sensitive coatings or bio-polymers that require oxygen-free environments for optimal film formation.

• Automated Dispense: Upgrade from manual dispense to programmable syringe pump dispense for precise, repeatable coating volume control(10 步或更多自定义速度分层).

• Extended Speed Range: Motor upgrade to achieve spin speeds up to 12,000 RPM for ultra-thin film applications.

• Footprint/Layout Customization: Benchtop configuration can be customized for specific laboratory space dimensions or integrated into an existing hood or glovebox.

• Software Customization: Extended data logging formats, custom recipe naming conventions, or API connectivity for LIS integration for regulated research environments.

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.

• Low Vibration: Vibration-damped chassis and precision-balanced motors ensure minimal mechanical interference with film uniformity, even at maximum speeds.

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.
