Customer Request

Customize a dedicated marking machine for giant screw drills to solve the three major pain points of difficult clamping, shallow engraving, and slow changeover in one stop.

The client is a domestic manufacturer specializing in downhole tools for oil extraction, mainly producing giant screw drill series products, which are mostly used in onshore and deep well oil and gas extraction projects. The original general-purpose marking equipment could hardly adapt to the production requirements of heavy-duty workpieces, and production problems were prominently concentrated:

Giant screw drills are long in length and relatively heavy in weight, so ordinary equipment cannot achieve workpiece rotary positioning. Conventional marking machines involve cumbersome clamping and can hardly achieve full-circumference engraving. Downhole tools operate for long periods in high-temperature, corrosive downhole environments, so product numbers, material codes, and factory steel grades require deep engraving. The standard marking pins on the original equipment are insufficient in hardness, resulting in inconsistent engraving depth, and the markings are highly prone to wear and blurring under the erosion of oil and gas media.

The company runs multiple non-standard downhole tool product lines in parallel, with a wide span of product specifications. General-purpose equipment requires long changeover and debugging cycles, dragging down the processing rhythm of the entire production line. After comparing and selecting among multiple options, the client intends to purchase localized equipment and gives priority to finding a technically mature Chongqing marking machine manufacturer to customize a dedicated solution that meets industry quality inspection and full-process product traceability requirements.

Solution

Tailored to the working conditions of petroleum workpieces and the client’s localized procurement needs, a customized complete marking machine solution was developed based on Chongqing’s local R&D advantages.

Customized tooling structure: Equipped with heavy-duty load-bearing roller brackets, suitable for the free rotation of giant screw drills several meters long, compatible with quick placement and positioning of multiple specifications of downhole tools, eliminating the workpiece disassembly process, and adapting to assembly line loading and unloading.

Core consumable upgrade: Carefully selected alloy steel marking pins, optimized impact force for the alloy steel base material of screw drills, accurately controlled engraving depth, with markings embedded into the metal matrix, resistant to downhole corrosion and impact, meeting petroleum equipment traceability standards.
 
Electronic control system optimization: A customized programmable control system stores marking templates for all categories of downhole tools in advance, allowing one-key parameter retrieval when switching models and greatly reducing changeover and debugging time.
Localized implementation service: As a professional Chongqing marking machine manufacturer, the company completed equipment assembly and sample polishing nearby, and conducted actual tests on hundreds of screw drill samples before delivery. After the equipment was completed, it provided on-site installation and debugging as well as on-site operator training.

Satisfaction

After the customized marking machine was officially put into production, it solved the client’s long-standing marking problems. The marking efficiency for a single giant screw drill increased by 65%, and the debugging time for changing product models dropped by 80%. The upgraded marking pins produce uniform and deep engraving, and all product markings successfully passed the factory quality inspection for petroleum equipment.

The client is highly satisfied with this customized Chongqing marking machine solution, product quality, and on-site after-sales service. The equipment has been selected as standard equipment for the new production line, and preliminary cooperation intentions have been reached for subsequent equipment for new downhole tool production lines.
The successful implementation of this customized marking machine project for giant screw drills is a successful practice of a local Chongqing marking equipment enterprise addressing the rigid demand of the oil extraction industry. In the future, the company will continue to iterate the structure of marking machines and marking pin processes, keep pace with the upgrading trend of downhole tool products, and rely on Chongqing’s regional intelligent manufacturing advantages to continuously provide customized marking solutions that are more closely aligned with actual production for the oil and gas equipment manufacturing field.
