Peristaltic Pump, stepper motor bracket
This ultra precise, peristaltic pump has been developed for use in a specific chemical analysis device for the beet sugar industry, a so-called Analyser. For this purpose, the pump needs to have an highly precise repeatability. Because of this, it is equipped with a stepper-motor for precise motion control of the main rotor drum.
In the old situation the motor was mounted with 4 stainless steel rods. The mounting rods were all CNC machined .
In the new situation, the optimized single part, replaces all 4 rods. Like the rods, the new, optimized bracket is also designed for stainless steel. The printproces of choice for this part is SLM printing.
For the new bracket a weight reduction of 19% was realized, compared to the old situation. The manufacturing costs dropped by 57%, comared to the old situation.
The new optimized bracket consists of one single part, printed with SLM print technique, in stainless steel.
Weight reduction: 19%
Manufacturing cost reduction 57%
Old situation, consisting of 4 CNC machined, stainless steel rods.
