Manual cylindrical screen printer

Types of manual cylindrical screen printers

A manual cylindrical screen printer is a printing machine that uses a curved surface to print images, logos, or text. They come in various types and designs.

• Direct-to-Object Screen Printer: This printer is designed to print directly onto objects. It uses custom tooling to hold and rotate the cylindrical object. It also uses a specialized screen or ink system that accommodates the curved surface of the object. Direct-to-object screen printers are commonly used for printing on bottles, cups, containers, and other cylindrical products.
• Manual Rotary Screen Printer: This type of printer uses a rotary mechanism to hold and rotate the cylindrical object, allowing for 360-degree printing. It is a simple, cost-effective way to achieve consistent prints on cylindrical surfaces. Manual rotary screen printers are commonly used for printing on drinkware, cosmetic tubes, candles, and other cylindrical products.
• Flatbed Screen Printer: While primarily designed for flat surfaces, some manual flatbed screen printers can be modified with a jig or fixture to accommodate cylindrical objects. The cylindrical printing attachment holds and rotates the object while the screen is pulled down to print. This method is sometimes referred to as “screen printing on the round.” While not as common as dedicated cylindrical screen printers, this modified setup can be a more affordable option for businesses looking to print on both flat and cylindrical surfaces.
• Manual Indexing Screen Printer: This versatile screen printer allows for manual loading and unloading of cylindrical objects onto a rotating platen. The operator indexes the platen to each station where the screen is lowered for printing. While more automated options are available, manual indexing screen printers are a cost-effective solution for lower-volume production runs of cylindrical objects.

Specifications and Maintenance of Manual Cylindrical Screen Printers

These are some of the specifications of a manual cylindrical screen printing machine.

• Screen Size

Manual cylindrical screen printers come with different screen sizes. This is the maximum area that the machine can print. Common screen sizes are around 300 mm by 400 mm. Larger screen sizes can be used to print bigger images on cylindrical products. However, the size of the print area is limited by the circumference of the cylindrical product.

• Maximum Print Length

The maximum print length is the length of the cylindrical product that the machine can print. This is limited by the vertical movement of the print carriage. Manual cylindrical screen printers have a print length of between 260 mm and 500 mm. These machines can be used to print on different lengths of cylindrical products, such as bottles, mugs, and containers.

• Maximum Diameter

This is the maximum diameter of the cylindrical product that can be printed. It is determined by the size of the holding fixture or chuck. The maximum diameter is usually between 60 mm and 120 mm. Manual screen printers can be used to print on small to medium-sized cylindrical products. Larger diameter cylindrical products can be printed using a manual screen printer with a large holding fixture.

• Construction

The machine is made of strong and durable materials, such as steel, to ensure that it lasts for a long time. Steel is also resistant to corrosion, which is an essential property when dealing with printing inks and cleaning solvents.

• Weight

The weight of the machine is an important feature when it comes to portability. A heavy machine is difficult to move around and requires a fixed place for operation. On the other hand, a lightweight machine can be moved around and placed on different surfaces.

Maintenance tips for manual cylindrical printers

Follow these maintenance tips to ensure that the machine works well and lasts for a long time.

• Keep it Clean

It is important to keep the machine clean at all times. This prevents the buildup of ink and dust that can clog the printing screen and moving parts. A clogged screen results in poor print quality, while clogged moving parts can cause damage to the machine during cleaning. It is important to use the right cleaning solvents and tools to avoid damaging the machine.

• Lubrication

Lubricating the moving parts is important to ensure smooth operation of the machine. This includes the print carriage, squeegee mechanism, and registration system. The type of lubricant and frequency of lubrication will depend on the manufacturer's instructions. It is important to avoid over-lubricating the machine, as this can attract dust and cause clogging.

• Regular Inspection

It is important to perform regular inspections of the machine to identify any issues before they become major problems. This includes checking for loose bolts and screws, worn parts, and damaged components. Worn parts, such as the printing screen and squeegee, should be replaced immediately to prevent poor print quality.

• Storage

When the machine is not in use, it is important to store it properly to prevent damage. The ideal storage place is in a clean and dry environment. This protects the machine from dust and moisture, which can damage the sensitive components.

• Operator Training

Proper training for operators is important for the long-term use of the manual cylindrical screen printer. This training helps to avoid common mistakes that can damage the machine. The operator should read the manual carefully and follow all of the manufacturer's instructions.

Manual cylindrical screen printer FAQs

Q1: What are the differences between manual and automatic screen printers?

A1: Manual cylindrical screen printers are operated by hand, making them suitable for small-scale projects. In contrast, automatic screen printers work well on a large scale and are more efficient.

Q2: What are the benefits of using a screen printer to print on round objects?

A2: With a screen printer, it is possible to print high-definition images, logos, and other designs on various round objects. This includes items made of plastic, glass, metal, and more. The image can be up to 360 degrees. Screen printing is also scratch resistant and long-lasting.

Q3: What is the best way to maintain a cylindrical screen printer manually?

A3: Regular cleaning is the best way to maintain a manual cylindrical screen printer. Wipe the ink residue off the frame, stencil, and squeegee immediately after printing. This can help prevent build-up and prolong the machine's life. Thorough cleaning of the machine should be done at regular intervals.

Q4: How does the screen printing process work?

A4: Screen printing involves pushing ink through a mesh stencil onto a surface. This process creates a printed design. The image is split into distinct colors that are then printed in separate layers. These layers combine to create the final design. Colors are printed one at a time. The screen is dried between each color application to ensure that the colors align correctly.
