Industry Background

In the automotive sector, electronic components such as sensors must consistently perform under demanding environmental conditions, including thermal cycling, vibration, humidity, and chemical exposure. To ensure durability and reliability, manufacturers rely on two-component (2K) epoxy potting, which provides mechanical protection and environmental sealing.

As production volumes grow, maintaining precision, consistency, and efficiency in adhesive dispensing becomes critical to ensure product quality while controlling operational costs.

Customer Introduction

The customer is a Bengaluru-based manufacturer specializing in high-performance automotive sensors. Serving major OEMs and Tier-1 suppliers, their production exceeds 2,000 units per shift. Each unit requires a precisely metered 1.2-gram application of two-part epoxy adhesive having 4:1 mixing ratio. The epoxy potting compound is purchased in bulk containers and refilled into self-metering dual cartridges for final dispensing on the assembly line.

Understanding the Problem

Despite high output and stringent quality requirements, the customer was using a basic benchtop cartridge dispensing system that failed to meet production demands due to the following challenges:

  • Inconsistent and inaccurate dispensing, leading to variation in potting volumes.

  • Frequent rework and material wastage due to unreliable shot delivery.

  • The valve did not have a fixed mounting method resulting in poor ergonomics and product inconsistency.

  • Excessive adhesive dripping post-dispensing, resulting in significant material loss and mess.

  • High maintenance need due to adhesive curing and clogging in valves.

These limitations compromised process reliability and significantly impacted operational efficiency and cost-effectiveness.

ADoST Solution

To address these challenges the customer partnered with the ADoST and the ADoST team conducted a thorough evaluation of the application process and recommended the ADoST CDS PRO — a purpose-built, precision dispensing system designed specifically for two part epoxy cartridge applications.

  • Precision-controlled volumetric dispensing, delivering ±0.006 gm shot repeatability for high process reliability.

  • Drip-free dispensing via the engineered ADoST Pinch Valve, minimizing adhesive loss and improving cleanliness.

  • Fixed valve positioning system through a robust ADoST valve stand, enhancing ergonomic consistency and application accuracy.

  • Auto purging feature reduced the risk of curing inside static mixers and optimizing consumable usage.

  • Reduced cycle times enabled by fast, repeatable dispensing with minimal manual intervention.
  • Maintenance-friendly design, reducing cleaning frequency and equipment downtime.

Customer Experience

Post-implementation of the ADoST CDS PRO system, the customer reported significant improvements:

  • Improved accuracy and repeatability of adhesive shots, ensuring consistent potting across all units.

  • Complete elimination of adhesive dripping, resulting in cleaner operations and reduced material consumption.

  • Reduced adhesive waste, translating into direct cost savings.

  • Enhanced operator efficiency, owing to ergonomic valve positioning and simplified handling.

  • Lower maintenance requirements, significantly reducing production interruptions.

Conclusion

The deployment of ADoST CDS PRO transformed the customer’s adhesive dispensing process from a manual, error-prone operation into a high-precision, reliable system. By solving key issues such as shot inconsistency, dripping, and maintenance complexity, the CDS PRO delivered measurable improvements in both quality and cost-efficiency.

This case reinforces ADoST’s commitment to delivering tailored, high-performance dispensing solutions that address real-world manufacturing challenges in the automotive electronics industry.
