Principle of Frozen Trimming Machine

The automatic jet type frozen trimming machine is a kind of ultra-low temperature using liquid nitrogen to rapidly embrittle the flashes of rubber, plastic products and magnesium alloy products, and in this state, the high-speed jetted frozen particles hit the product's edges. It is a special trimming device that can remove the flashes of the products with high quality and high efficiency while maintaining the physical properties of the rubber, plastic products.
During the processing, the temperature (-130℃~0℃, LSR parts should be -110℃), speed (0-7200r/min), and wire diameter of the plastic particles (0.3-1.5mm, provided by Supplier) can be adjusted to ensure that the products are not frostbitten and bruised to ensure good quality of the products.

Project Analysis of Frozen Trimming Machinery
Product: LSR Tip
Status: After being frozen trimmed
Project-Analysis-Product-LSR-Tip-Status-After-Being-Frozen-Trimmed
Step 2: Put the basket filled with the products into the frozen trimming machine Step2 Step 4: After the automatic cycle is completed, the device alarms the notification, and the operator opens the door and takes out the products. Step4
Step 3: After setting the parameters, close the door, start automatic mode, and automatically process the products.
Note: After the parameters are set, there is no need to reset any subsequent cycle processing.
Step3 Step 5: Remove the products from the basket and clean the surface of the products. After cleaning is complete, you can use the products.  

Production Capacity of 60L Frozen Trimming Machine
Calculated in 8 working hours per day:
Daily capacity = single batch throughput (kgs) * number of processing per hour * working hours

=4*6*8

=192kgs

Conservative estimation, based on working hours, the 8-hours daily processing capacity is 192kgs

Technology and Advantages of Frozen Trimming Machinery
Advantages of the frozen trimming machines:
1. High processing efficiency: To process products in batches in a short time, and its efficiency is much higher than manual operations'. High-efficiency and high-yield can greatly save the cost of employing people and create more profits.
2. The processing quality is reliable: The products are processed by the machine, in the whole process of operations, the participation of worker is very low, the processing quality of the products is not affected by the state of the worker, and the quality can be maintained consistently.
3. Reducing scrapping: The workers processing soft rubber products, in the event of mistakes, may damage the appearance of the products, resulting in products scrapping, and the process of freezing and trimming can maintain accurate processing and eliminate unnecessary cost waste.
4. The applicability of the machine is wide: The machine can not only deal with the burrs of soft rubber products. For other zinc alloys, rubber, silica gel and specific plastic products, as long as the burrs can be controlled within a reasonable thickness range, the process can be used.
5. The equipment uses liquid nitrogen as the refrigerant (the liquid nitrogen returns to the atmosphere after gasification), and has a dedicated dust collector, which is absolutely environmentally safe.
