Profile Design

Aluminum extrusion die manufacturing is a critical task for productive improvement and increasing potential of competition in aluminum extrusion industry. It causes to meet the efficiency not only consistent quality but also time and production cost reduction. Die manufacturing consists first of die design and process planning in order to make a die for extruding the customer’s requirement products. The efficiency of die design and process planning are based on the knowledge and experience of die design and die manufacturer experts. This knowledge has been formulated into a computer system called the knowledge-based system. It can be reused to support a new die design and process planning. Such knowledge can be extracted directly from die geometry which is composed of die features. These features are stored in die feature library to be prepared for producing a new die manufacturing. Die geometry is defined according to the characteristics of the profile, is called product data, so we can reuse die features from the previous similar profile design cases. This paper presents the artificial neural network to assist aluminum extrusion die design and process planning based on collaborative design methodology. Product data can be shared and distributed in die design team members via computer network technology. This product data is used to support die design and process planning. Die manufacturing cases in the case library would be retrieved with searching and learning method by neural network for reusing or revising it to build a die design and process planning when a new case is similar with the previous die manufacturing cases. The results of the system are dies design and machining process.

Realistic Representation

Of the various boundary conditions that are relevant for the correct modeling of the extrusion process the realistic representation of the friction in the die is important since it has a significant influence on the profile temperature, the strain and strain rate distribution in the die. In order to investigate the influence of the die geometry, respectively the geometry of the die bearing, a four-hole die with exchangeable inserts was designed. Thereby each of the four inserts was equipped with a thermocouple to record the profile temperature at the die bearing. Through the combination of different die bearing geometries (cylindrical, 0.5° closing, 1° closing, 0.5° opening) in the same die the influence on the extrusion speed and profile temperature could be evaluated with the exact same extrusion conditions. The observed differences in the temperature and speed in respect to the geometry of the die bearing where evaluated and implemented in a FEM simulation in order to validate the underlying friction model.

Product Weight

Slide rails are usually fabricated by roll forming and are used in kitchenware and cabinets mostly. However the product weight of slide rails is increased because larger dimensions are required to bear larger load when they are used in dies and warehouses. International suppliers start to develop Aluminum slide rails to decrease the product weight in recent years. The manufacturing and functional feasibility of Aluminum slide rail were discussed in this study. The Aluminum slide rail was designed according to ready-made slide rail, and the aluminum alloy was selected with required mechanical properties. The suitable extrusion die was designed and direct extrusion parameters of extrusion ratio, extrusion temperature, extrusion speed and extrusion load are also considered. The extrusion process of aluminum alloy was simulated by CAE software to check the mold and process design. The extrusion part of aluminum slide rail was carried out by extruder to verify the simulation results.

Aluminum Profile Extrusion

According to the similar characteristics of structure, geometry and constraints conditions in the same type of extrusion process, the intelligent design system of a square tube aluminum profile extrusion forming process was established in this paper based on the VB programming language, with using parametric programming language APDL provides by ANSYS software. The parameterized optimization design plan of pre-treatment and post-processing of ANSYS analysis during a square tube aluminum extrusion forming process was achieved, and the program of a three-dimensional model of the extrusion die under Visual Lisp environment was also programmed. The human-computer interaction intelligent design system which combined with pre-processing of semi-finished product, finite element analysis of extrusion die strength, extrusion die temperature field analysis, structural optimization of the die was realized. The research results show that the system can provide program decision-making, structural design, performance analysis and graphics treatment for the actual extrusion productions of square tube aluminum extrusion process, which reduced the design time of the technical staff, and saved design cost.

Rheology of polymer-metal powder mixture containing a significant amount of metal powder loading determines its flowability through an extrusion die. To make sheets from such mixtures, geometries based on Coat-hanger, Fishtail and ‘T’ type designs are often used. Flow properties such as flow rate, viscosity, residence time, instantaneous velocity and pressure distribution in different type of dies have been used in simulations in Ansys (CFX or fluent). The present paper describes the special design of the fishtail type die geometry with adjustable part at lip land to make sheets from a polymer-metal powder mixture by extrusion. This also includes the design of primary manifold, tapered pre-land, secondary manifold and lip land geometries to obtain uniform velocity at the exit of the die and as uniform a pressure distribution as possible. It includes designing of suitable die profiles in each of these four zones based on the experimentally established constitutive equations using a Melt Flow Index tester.

Predicted Values

A viscoplastic model for extrusion is discussed which simultaneously predicts the deformation field, optimal die geometry, and plastic boundaries. The die geometry and plastic boundaries are expressed in terms of chosen trial functions that satisfy certain geometrical and physical constraints. The variational power integral is minimized in the trial plastic domain using FEM technique to determine the deformation field and shape coefficients for the die contour and plastic boundaries. The proposed method is implemented for the optimal design of an axisymmetric streamlined die. The predicted values are in reasonable agreement with the experimental observations and are in conformity with the results published earlier.
