Case Description

A well-known automotive paint manufacturer provides high-quality automotive coating products to many automobile manufacturers. Automotive paints have strict requirements for coating uniformity, gloss and durability, and any defects in the production process may affect the appearance and quality of the automobile. Before adopting Rotary Lobe Pump, the enterprise's traditional screw pumps were prone to shear force when conveying raw materials such as high-viscosity resins and hardeners for automotive paints due to the structural characteristics of the screw pumps, which led to the breakage of the resin molecular chain, affecting the curing performance of the automotive paints and the quality of the coatings. Moreover, the flow rate of the screw pump fluctuates greatly, making it difficult to precisely control the ratio of raw materials, which results in differences in the performance of different batches of automotive paints, and increases the difficulty and cost of the coating process for automobile manufacturers.

Solution

The company introduced 5 low shear Rotary Lobe Pump from Bonve. These Rotary Lobe Pump adopt the advanced low shear design concept, which can control the shear force to a minimum when conveying high viscosity raw materials, effectively protecting the integrity of the resin molecular chain and ensuring the curing performance and coating quality of automotive paints. Its stable flow output and precise flow control function can realize the precise proportioning of raw materials and ensure the consistency of the performance of each batch of automotive paint products.

The equipment supplier has established a long-term cooperative relationship with the enterprise, regularly carries out maintenance and repair of the equipment, and solves problems arising during the operation of the equipment in a timely manner. After the introduction of the Rotary Lobe Pump, the coating uniformity, gloss and durability of the automotive paint have been significantly improved, and the product quality has reached the international advanced level, which meets the strict requirements of automobile manufacturers for high-quality automotive paints, and further consolidates the leading position of the enterprise in the automotive paint market.
