ProPlas Technologies

Custom Injection Molding of Ultrasonic Dental Instruments

A customer in the dental industry commissioned ProPlas Technologies to fix issues with a custom 2 piece handle for an ultrasonic dental instrument. The existing tooling was optimized, and PC/ABS alloy was selected as the molding material. Scientific molding techniques were utilized in an 85 ton electric injection molding machine to eliminate existing cosmetic and fit issues and produce product which met the customer’s expectations. The tightest tolerances of ±0.004” were easily achieved during manufacturing. Overall finished part dimensions were approx. 5” in length, with a diameter of 5/8”. Throughout the process, dimensional, functional and visual testing methods were implemented to ensure quality and integrity.

Turnaround time for this project was 3 weeks, with 2,000 units produced per month and shipped to the customer’s location for final assembly and ultimate shipment throughout the World.
