Redesign

Effective powder metallurgy design starts with knowledge. Burgess-Norton's combined expertise in best-practice manufacturing techniques and world-class engineering drives our results-focused PM solutions.

Burgess-Norton designs the PM part in the context of the whole assembly process. We understand the parts assembly challenges, we know where and how to apply the right PM technologies to optimize product performance and drive value to your bottom line.

We closely collaborate with our customers starting with the initial PM part concept stages. Our engineers begin by first examining your assembly operation's identifying critical areas of opportunity to reduce waste, optimize assets and elevate productivity. PM Prototypes are then designed and tested to examine performance in assembly. High value is placed on the designer's manufacturer interaction. Our critical design and testing process accelerates the development cycle and optimizes your performance requirements.

Specifying a PM Part

Let Burgess-Norton take a fresh look at how and where powder metallurgy can be utilized to make the most of your capabilities.

When requesting a quotation, accurate part performance specifications must be provided. In describing a part, be sure to stress its function and critical requirements for satisfactory service. See the checklist below for guidelines for specifying a PM part.

Checklist for Specifying a PM Part

This checklist has been created to give those considering the use of PM technology an idea of the information often needed to design a typical part.

1. Part drawing.
2. Subassembly drawing to illustrate where and how the part is used within the total design.
3. What are the estimated annual quantity requirements and at what quantity level will the weekly or monthly release be?
4. Identify current successful material (if already established).
5. Identify any problem with the current design.
6. Identify the critical performance requirements, e.g., strength, wear resistance, corrosion properties, impact resistance, weldability, pressure tightness, magnetic response, thermal conductivity, applicable to your part.
7. Identify critical tolerance issues.
8. Identify the need for special surface treatment, e.g., corrosion protection (oil dip, plating, paint, phosphating), shot peening, and so on.
9. Identify the need for properties of heat treatment, e.g., hardness (case/case), wear resistance, increased strength and lower density, and so on.
10. Identify any special test requirements, e.g., special test fixture or equipment, performance level of current design, static or dynamic, and so on.
11. Gears have unique requirements that dictate the need for specific data such as the following:
    1. Number of teeth
    2. Diametral pitch
    3. Pressure angle
    4. Measurement over wires
    5. Tooth thickness
    6. Root and tip radius
    7. Helix angle and hand
    8. AGMA-quality class
    9. Mating gear data and nominal center distance
    10. Inspection requirements runout; pitch; profile and lead tolerance; or tooth-to-tooth, total composite tolerance and testing radius
