The BP-4530-3 Automatic Stacking Tofu Molds Machine is a complete turnkey solution designed for manufacturers entering the molded fiber packaging industry or product development. This system differs from the standalone machines in that it integrates all the components required for full-scale production, thereby eliminating the challenge of acquiring and interfacing separate machines.
The 3-template automated transfer system accelerates production by transferring molds through the forming, pressing, and cooling phases on autopilot. This shift in labor reduces the amount of manual work needed, decreases the chances of human error, and provides reliable uniformity in the quality of the end products in a single production run. The system can work uninterrupted in a continuous cycle, with one mold being formed, one pressed, and a third in the cooling stage. This ongoing process inversely decreases the amount of idle time for the system.
A range of adjustable mold sizes between 300 and 470 mm offers versatility. This feature allows manufacturers to produce different sized products without the added expense of purchasing numerous machines. Flexibility extends to the maximum product height of 100 mm, from shallow trays to deeper containers. This design feature makes the system adaptable to a range of market needs.
A 5-ton hot-press pressure system with a robust interface to pulp and product requirements helps the 5-ton system handle different densities. Uniform temperature distribution—which is key for consistent product quality and adequate moisture evaporation for proper finish—is ensured by the action of the dual 8 KW heating elements (upper and lower). This capacity also greatly decreases the time and energy needed for drying.
This machine is distinguished mainly because of the standard complete production line construction. The pulp-mixing pump and bucket set up a consistent pulp slurry, and the pulping machine then performs the processing of the raw materials. The combination of the cold and hot vacuum pumps performs simultaneous and efficient air moisture extraction. For the entire production, the pulp refluxing pump and bucket ensure the maintenance of the proper production pulp consistency. The vacuum water refluxing tank autogenic water refluxing system is designed to manage the recovery of water to reduce waste and operational cost. Last touches on the products are done by the trimming machine to provide the finishing touches.
This system is appropriately sized to handle small batch commercial production, custom orders, and product development for a daily output capacity of 50-100 kg. The limited footprint of this machine enables the use of facilities with restricted production space while the complete integration provided eliminates the need to manage multiple separate systems.

Most Frequently Asked Questions

Q1: What products can this complete production line manufacture?
This system manufactures a range of molded fiber products which include food containers, egg cartons, fruit trays, electronics packaging, protective inserts, eco-friendly tableware and other similar items. It can also handle the adjustable mold size range of 300 to 470 millimeters in width and 100 millimeters in height which permits a greater range of designs and products to be produced for varied industry requirements.
Q2: Are there any specific skills needed for using this equipment?
The automated system does make operation easier to some extent, but some basic training is advisable. We also offer complete operator training for each component of the system- pulping, mixing, forming, pressing, trimming. Integrated systems are easier to learn, as opposed to learning how to operate different systems in isolation.
Q3: What raw materials does this production equipment operate on?
This system is capable of processing different plant fibers and even recycled paper along with bagasse, bamboo pulp, wheat straw, and some other agricultural waste materials. Different types of fibers can be used in the pulping machine and mixing system. This gives you some flexibility in the types of materials you can source and the characteristics of the end product.
Q4: What is the system’s power and water requirement?
The machine needs dual 8 KW heating power (16 KW total) plus some more for the pumps and automation controls. It also needs an industrial level electricity supply and water supply. A vacuum water re-fluxing tank is in place to conserve water. Our installation team gives you all the necessary info regarding the utilities.
Q5: What kind of warranty, backup, and declaration of support do you have?
All system components and the main machine, pumps, tanks, and trimming equipment have warranty coverage, and we provide complete training and professional installation. While our support team offers all maintenance to keep the system running, troubleshooting, and even providing assistance with modified parts, we offer shipping with warranty details, and shipping info as well.
