The Growing Demand for Industrial Screen Printing Automation

Manufacturers across cosmetics packaging, glass containers, plastic products, electronics, and industrial components are facing a common set of pressures: elevated labor costs, inefficiencies in manual screen and pad printing loading and unloading, alignment and color matching errors during multi-color print runs, difficulties printing on irregular or non-flat surfaces, and costly production downtime caused by a lack of remote technical support. These pain points are pushing the industry toward automated, unmanned production lines—and Shenzhen klk Electronic Equipment Co., Ltd., operating under the brand Kar Lee Keung (KLK), has positioned itself directly at this intersection of demand and capability.

Established for over 28 years and headquartered in Longgang District, Shenzhen, China, KLK is a China-based manufacturer specializing in industrial printing equipment, including automatic screen printing machines, pad printing machines, hot foil stamping machines, labeling machines, and customized printing automation solutions. Its business coverage spans Asia and global markets, with a service base of over 500 industry clients and a workforce of more than 200 employees operating from a 9,000 square meter facility.

What Sets KLK’s Automation Approach Apart

KLK’s core value proposition centers on delivering customized, high-efficiency machinery that minimizes manual handling and drives the transition toward automated, unmanned production lines. This is achieved through several differentiated technical approaches:

• Integrated operating software with servo systems: This combination enables high-accuracy graphic placement, directly addressing alignment and color matching errors that plague manual multi-color print runs.
• Remote configuration updates via private communication servers: Rather than requiring on-site technicians for every adjustment, KLK enables remote debugging and parameter modification, minimizing maintenance delays and reducing field downtime.
• Direct combination of injection molding lines with print systems: This creates touchless product handling, eliminating manual transport steps between molding and decoration phases.
• Pad printing and customized printing systems: These allow printing on curved, cylindrical, irregular, and three-dimensional product surfaces—solving a challenge that conventional flat-surface screen printing cannot address.

At the technical core, KLK’s high-accuracy printing platform integrates Mitsubishi operating systems, Panasonic servo motors, and closed-loop drives. The company applies CCD camera alignment for precise substrate registration, PLC and touchscreen controls for streamlined operator use, and flame surface treatment to improve ink adhesion on plastic containers. These technology partnerships with Mitsubishi (operating systems and PLC controllers) and Panasonic (servo motors and closed-loop drives) form the backbone of KLK’s equipment reliability.

Product Line: Automatic Screen Printers and Beyond

Among KLK’s flagship offerings is the Automatic Screen Printer, including Model KLKZS22, a high-efficiency silk screen printing system designed for automated multi-color graphics application. This equipment directly targets high labor costs from manual part loading, color alignment mismatches, and slow printing throughput through:

• CCD Camera Registration, which automatically aligns substrates for multi-color runs, solving color matching and alignment errors.
• Panasonic Servo Motor Control, which drives screen strokes and product rotations with closed-loop accuracy, ensuring clean, consistent print transfers.
• Mitsubishi PLC Operating System, controlling machine cycles and timings via a touchscreen interface to simplify setup changes for operators.
• Flame Treatment Unit, pre-heating plastic container surfaces before ink application to solve poor ink adhesion problems.

Beyond screen printing, KLK’s product matrix extends into Pad Printing Machines for multidimensional surfaces, Hot Stamping (Bronzing) Machines for high-durability metallic finishes, and UV Curing Ovens for rapid ink drying. On the automation side, the company offers Fully Automatic Plane Mask Equipment, Integrated Injection Molding-to-Printing Lines, and Customized Conveyor & Assembly Systems. Rounding out the offering are Tunnel Ovens, Cabinet Ovens, and Eco-Friendly Water Curtain Spray Booths for baking, curing, and spraying applications.

Real-World Application: Case Evidence Across Industries

KLK’s automation solutions have been validated across multiple manufacturing contexts:

In an injection molding automation case, a plastic injection molding facility requiring post-mold decoration integrated KLK’s Injection Molding-to-Printing Line with custom conveyor systems. This helped the manufacturer achieve automated loading and unloading plus integrated product transfer, ultimately delivering touchless finished-product output and removing manual intervention between injection molding and printing phases.

In a cosmetics packaging case, a cosmetic packaging supplier handling varied bottle shapes implemented KLK’s Multi-Color Rotary Screen Printing Equipment with CCD camera alignment to print high-accuracy multi-color patterns on curved and oval glass containers. The result was high-accuracy multi-color registration on curved and oval glass bottles with smooth ink transfer, minimizing color alignment mismatches and reducing manual setup times.

In a healthcare equipment case, a personal protective equipment manufacturer scaling up supply installed KLK’s Fully Automatic Plane Mask Equipment with advanced feeding systems, achieving automated fabric feeding and integrated ear-loop welding, delivering finished masks through a complete automated line while eliminating manual contact.

In a wine packaging case, a high-end wine bottle packager utilized KLK’s Hot Stamping Machines and Automatic Screen Printers to combine metallic foil decorations with silk screen details, achieving high-quality brand decoration and detailed hot stamping foils that established high-durability print designs and enhanced overall packaging aesthetics.

Service Model Supporting Long-Term Automation Success

KLK’s service capabilities extend well beyond equipment manufacturing. The company provides non-standard design customization, technical consulting, and production line integration, covering equipment design, system customization, on-site and remote installation, and remote maintenance support. Its delivery capability includes designing and deploying integrated assembly lines and multi-stage printing operations, backed by remote program updates and troubleshooting via private communication servers to reduce field downtime—a direct answer to the industry’s costly production stoppages caused by delayed technical support.

The company holds ISO 9001:2000 Quality Management System Certification and maintains a visible industry presence as a regular participant and exhibitor at CHINAPLAS, Asia’s major plastics and rubber trade exhibition, reinforcing its engagement with regional and global manufacturing communities.

Looking Ahead

As manufacturers in cosmetics, electronics, stationery, and industrial components continue to seek unmanned feeding systems, direct injection molding integrations, and high-accuracy registration systems, KLK’s combination of proprietary technology integration—Mitsubishi controllers, Panasonic servo systems, CCD vision, and private-server remote support—positions the company to serve the evolving needs of industrial screen printing automation. With over 28 years of manufacturing experience and a client base exceeding 500 companies, KLK’s approach reflects a broader industry shift: away from manual, error-prone printing processes and toward integrated, remotely supported, automated production lines built for consistent quality and reduced downtime.
