Meeting Points vs. Bumping


There are two different methods for producing wire-drawing dies. The first method is the meeting point while the other is bumping. Each has its advantages and drawbacks, which should be evaluated to make sure dies are produced to the highest quality with the least amount of time. This paper is intended to discuss both methods to help in the decision of which is best suited for each application.


Cost per Ton compared to Cost per Die


In most drawing factories the only analyzing of die cost is the actual purchase cost, die shop overhead, how many dies are made per operator or how fast the die can be re-worked. The real value the die holds is in the mills overall production efficiency and should be looked at in production not purchase cost or overhead terms. Simply put the more die changes, scrap and customer returns the less efficient the die shop or supplier is. This paper is intended to layout how dies should be analyzed, what effect the die has on production, problems with focusing on low cost die production and cost analysis of the dies in production.


Die Measuring Technology Overview


The die is the heart of any drawing operation and one of the most important factors in generating the wire or tube quality. It is one of the few items that can be inspected quickly to determine if it is causing a drawing problem. The die consists of two internal forms, conical angle and cylindrical bearing, that are very difficult to measure in diameters under .035” (0.9mm). The purpose of this paper is to cover the different inspection systems, techniques for measuring the different characteristics of the die, reality in getting accurate measurements and following inspection standards to ensure measurement results.


Coiled Bar Design

  Traditional die designs can cause many problems in drawing larger diameter wire. Current carbide nibs do not provide enough height to allow the use of proper drawing angles for most reductions taken on larger material, which, leads to poor material deformation, surface defects and customer rejects during forming. This paper is intended to suggest solutions to the current deficiencies, suggest practical solutions to existing dies and how to better design dies to draw larger diameter wire.


Why Choose Die Quip


Die Quip was founded as an equipment builder to make finishing dies faster and easier for an in-house die shop.  All of our equipment is designed using sound machine designs, time tested work holding methods and built on a rigid platform to consistently make heavy cuts. We are not a die shop that designed equipment for internal use for production of new dies. This makes our philosophy in building tungsten carbide draw die working equipment different than our competition. We have the widest diameter working range of any company in the industry and have products for the wire, bar and tube drawing industries.
