Most factory losses are visible. A machine stops. Production slows down. Material gets wasted. Dispatch is delayed.But one of the most expensive losses inside a manufacturing plant often remains invisible until a customer complains.

The product may have passed inspection. The order may have been dispatched on time. The production report may look completely normal. Then the calls begin.

The coating starts peeling. Corrosion appears earlier than expected. The finish looks inconsistent. The product does not perform the way the customer was promised.

According to surface-finishing entrepreneur Raunak Parashar, the customer complaint is rarely where the problem begins. It is simply where the factory finally notices it.

The Problem Starts Much Earlier

Raunak Parashar is the Founder of DTRA Engineers, a company specialising in industrial paint shop solutions and turnkey surface-finishing systems.

With decades of family and professional exposure to the industry, Parashar has worked closely with manufacturers across automotive components, architectural aluminium, home appliances and several other industrial categories.

DTRA Engineers has worked on more than 2,000 installations and client requirements across India. Its portfolio includes powder coating plants, liquid painting lines, pretreatment systems, CED coating systems, industrial ovens and customised surface-finishing equipment.

Through this experience, Parashar has observed that many quality failures begin long before the finished product reaches the customer.

The problem may start with inadequate pretreatment, incorrect curing parameters, inconsistent coating application, an unsuitable plant layout or equipment that was never designed around the factory’s actual production needs.

Yet because the line continues to operate, the problem often remains unnoticed.

Conveyors keep moving.

Components continue entering and exiting the paintshop.

Production targets may still be achieved.

But beneath that visible activity, rejection, excess powder consumption, energy waste, repeated handling and inconsistent finish quality may already be affecting the business.

When a Running Line Is Not a Healthy Line

One of the biggest misconceptions in manufacturing, Parashar believes, is that a running paintshop is automatically a performing paintshop.

A line can remain operational while quietly losing money every day.

The losses may initially appear too small to attract attention. A few rejected components. Slightly higher fuel consumption. Occasional rework. Minor variations in finish quality.

Over time, these “small” issues begin affecting production costs, maintenance requirements, delivery commitments and customer trust.

By the time complaints reach senior management, the factory may have already paid for the problem several times over.

This is why manufacturers must evaluate paintshop performance beyond output alone. The right questions are not limited to how many components the line produces, but how consistently it produces them, how much rework it creates and what it costs to maintain that quality.

The Lowest Quotation Can Create the Highest Cost

Factory owners often compare paintshop solutions through their initial investment.

But the cheapest equipment or layout does not always create the lowest operating cost.

A decision that saves money during installation can increase long-term expenses through maintenance, production stoppages, energy inefficiency, material wastage and customer rejection.

Parashar’s approach at DTRA Engineers begins with understanding the manufacturer’s component size, production target, available space, coating requirement, quality expectations and expansion plans.

The objective is not simply to recommend machinery. It is to design a system around the result the manufacturer needs to achieve consistently.

This changes the conversation from:

“Which machine should we purchase?”

to:

“What must this paintshop deliver every day?”

Building Accountability Into the Paintshop

Turnkey surface-finishing systems require several processes to work together.

Pretreatment must prepare the surface properly. Material handling must support the required throughput. Coating application must remain consistent. Ovens must maintain the correct temperature profile. Operators must understand the process, and the equipment must remain serviceable over time.

When these elements are planned separately, accountability becomes fragmented.

DTRA Engineers’ one-window model connects consultation, design, manufacturing, installation and commissioning through a single solution provider.

For Parashar, the desired result is not merely an installed paintshop. It is a system that protects production quality, operating efficiency and the manufacturer’s reputation.

“A customer complaint is often treated as the beginning of a problem. In reality, it is usually the final warning. The loss may have been building inside the paintshop for months,” says Parashar.

His message to manufacturers is direct: do not wait for customers to reveal what the factory should have identified earlier.

Because the most dangerous factory loss is not always the one that stops production.

Sometimes, it is the one that allows production to continue while quality, money and customer trust quietly disappear.
