- Screen printing machine: construction uses a plastic body, galvanized screws, and a bearing sleeve made of aluminum alloy. Available in three table sizes: 240 x 300 mm, 405 x 310 mm, and 590 x 440 mm. Maximum screen thickness 40 mm. Base thickness 1.37 mm; table thickness 1.46 mm. - Table upgrade: the back side of the manual printing table is now painted to improve rust protection. The reinforcement plate has been upgraded from a single-sided to a double-sided design, and the plate thickness increased from 0.84 mm to 1.46 mm. - High temperature baked enamel for the entire machine: the coating is less prone to peeling and provides better rust protection. The base, squeegee clamp, and counterweight block have been switched from spray coating to baked enamel. - Aluminum alloy bearing sleeve: the small screen printing machine has been upgraded from a recycled plastic bearing sleeve to an aluminum alloy bearing sleeve with a sealed bearing, improving rust resistance. Zinc plated screws have smooth threads, are easy to tighten, and are less likely to snag. - Use scenarios: ideal for small-batch screen printing in studios or workshops on textiles and plastics, with screen sizes up to 590 x 440 mm. Suitable for prototyping and test runs requiring durable rust protection and stable performance. Appropriate for educational settings and hands-on training to teach basic screen printing techniques and equipment handling.
