Powder Metallurgy · Sintered Part Manufacturing
Blueprint to Production: Precision Sintered Metals
Green Metalurji develops custom powder metallurgy solutions for gear components, functional mechanical parts, and self-lubricating bronze bearings. We plan the entire process—from technical feasibility to die design, and from sample approval to controlled series production—based on your application’s performance requirements.
Technical Feasibility
The part’s suitability for powder metallurgy and mass production is evaluated from a technical perspective.
Project-Specific Mold
A custom mold is developed taking into account the part geometry, tolerances, and production volume.
Batch Production
We provide a mass production infrastructure to ensure consistent quality and controlled unit costs.
Sampling & Quality Control
Pre-production samples are precisely measured, evaluated, and submitted for client approval.
Project-Specific Sintered Parts
Every application has different load, friction, speed, tolerance, and operating conditions. For this reason, we work together to design the part geometry, material composition, and manufacturing process to ensure optimal performance for the specific system in which it will be used.
Sintered Gear Parts
Helical, planetary, chain, ring, and custom gear solutions for gearboxes, motors, pumps, automation, and power transmission systems.
Bronze Beds
Bearing solutions that retain oil within their controlled porous structure, operate quietly, provide low friction, and significantly reduce overall maintenance requirements.
Sintered Mechanical Parts
Pump assembly parts, shaft hubs, cams, rotor and stator components, piston washers, and project-specific functional mechanical parts.
Door, Window, and Lock Systems
Advanced, compact, precision-engineered sintered gears and mechanism parts suitable for mass production, designed for smart window and door locks as well as mechanical security systems.
The Right Manufacturing Method for Your Project
Powder metallurgy is a strong manufacturing alternative for projects where the same geometry is repeated regularly, production volumes are moderate to high, and the cost per part needs to be controlled. Our technical team evaluates your part—whether it is currently produced via CNC, casting, or another method—in terms of moldability, material structure, tolerances, operating conditions, and annual production volume.
If your part has several of the following characteristics, powder metallurgy may be a suitable manufacturing alternative:
- The need for regular production at medium or high volumes
- Maintaining the same dimensions and geometry in every part
- Part design requiring multiple CNC operations
- The current production method, which results in high material waste
- Complex gear, channel, hub, or stepped geometries
- The need for controlled density or a porous structure
- The goal of reducing unit costs through mass production
- Regular orders of the same item over a long period of time
Controlled and Traceable Production Process
We approach every project not merely as the production of a single part, but as a holistic engineering process comprising materials, geometry, tolerances, tooling, processes, and quality criteria, and we offer you customized solutions.
Technical Analysis and Feasibility Study
The part’s technical drawing, function, operating conditions, tolerances, and annual production volume are reviewed to assess its suitability for powder metallurgy.
Material and Process Planning
The production steps are determined based on the expected strength, wear resistance, density, porosity, and friction properties of the part, as well as the operating environment, using the appropriate metal powder.
Mold Design and Preparation
The part geometry is adapted to the pressing direction and mass production conditions. The die set is prepared according to critical measurement points and target tolerances.
Powder Compaction
The prepared metal powder is compacted within a mold under controlled pressure to form the part’s rough geometry and achieve the desired density structure.
Controlled Sintering
The pressed parts are sintered in controlled-atmosphere furnaces at a specified temperature for a specified duration. This process results in the formation of metallurgical bonds and the attainment of the required mechanical properties.
Calibration and Secondary Operations
Depending on the application's requirements, dimensional calibration, oil impregnation, heat treatment, surface treatment, or complementary mechanical operations are performed.
