Welding Processing in Die CorrectionIf the velocities between the outside of the profile and the central portion are close tobeing equal and the pressure within the die is great enough then a eutectic weld between consecutive billets will be achieved. The outer friction, as already discussed, is gen

Brief introduction of deformed Aluminum alloy1.1 Classification of deformed aluminum alloyAluminum alloy root its chemical composition of the production process characteristics of different, can be divided into casting aluminum alloy and deformation aluminum alloy. Deformed aluminum alloy has high

Porthole Die Stress checking.This is a quick and simple method used to check if a given die design has sufficientstrength and the likelihood of failure of the die during the die’s life time. This system isbased on the calculation that is used by the Die-maker and has been adjusted to a tableform. Th

Why Dies Perform DifferentlyIt has long been a mystery as to why some dies turn out to be a major problem for theTechnician and the Production team. These particular dies can be to produce a relativelysimple profile but can be the cause of many discussions and possibly heated exchangesbetween Techni

WHY WEB (BRIDGE) GET CRACKED EXTRUSION DIEAfter several production runs the mandrel will begin to deflect with the resultingcracks appearing on the weakest part of the webs ( maybe noticeable more quickly ondies with a high extrusion ratio ). The cracks if left unattended will worsen and in severeca

How to improve extrusion die lifeThere are many factors that can affect industrial aluminum extrusion die life of, in addition to the extrusion die structure design and strength, mould materials, hot and cold processing and electrical processing technology, heat treatment and surface treatment techn

Detailed explanation of production steps of industrial aluminum profileTo produce aluminum extrusions, we must use aluminum extrusion production line equipment, a complete set of aluminum extrusion production line equipment a total of 6 parts: aluminum extrusion machine, billet cutting hot furnace,

Factors that should be considered in extrusion die design1 In accordance with the structure of the aluminum extrusion machine, die designers must consider aluminum products surface, the choices of the press machine, the customer product requirements, service condition , the complexity of the produ

Principles and steps of aluminum extrusion die designDetermine design cavity parametersFirst of all, designers get the section drawings, the first is to determine the machine, according to the extrusion ratio, section section of the maximum circumfluence is how much, and complexity to decide which m

Structure of Aluminum Extrusion DieAluminum extrusion die is made of H13 steel.The die can be used after nitriding.The whole die is composed of three parts: die feeder, die plate and backer. Now let’s focus on the structure of normal dies.1. Working beltThe working belt is perpendicular to the worki

Process Flow

Die correction is an important factor in aluminum extrusion processing, there is no 100% perfect die, first pass rate only 60% for the average. Only through die correction, product quality and processing efficiency can be improved continuously.Last time we discussed some die corrections about hollow

Die life is related to die type and structure, it is a certain period of die material performance, die design and manufacturing level.The comprehensive reflection of die heat treatment level and use and maintenance level.To a certain extent, die life reflects the level of metallurgical industry and

Two kinds of extrusion process characteristics of aluminum extrusion machineA, Hot extrusion process characteristics:1) Hot extrusion is an early extrusion forming technology used in several extrusion processes. It is a kind of extrusion forming of metals under hot forging temperature with the help

Introduction to light wave die furnaceI Main body structure of furnaceFurnace body: outer sealing plate + stainless steel inner liner +1160 high temperature insulation cotton.Heating component: infrared ray tubeDoor: stainless steel lining + steel frame + silicate fiber cotton +3mm outer sealing pla

Since the aluminum profile was born, it has experienced a vigorous development, and every year with a speed of nearly 20 ~ 25% in the development. With the progress of The Times and the development of science and technology, improving production efficiency has become the greatest competitiveness of

Production Guide for Heat Sink Aluminum Profile As we all know, aluminum alloy has good heat dissipation performance, in our daily life, aluminum alloy heat sink is widely used, and the heat sink market is also very large.As a producer, heat sink profile is a kind of high difficulty and high cost o

Introduction to Heat TreatmentThe aluminum extrusion dies use hot steel as the base material. It needs to go through the heat treatment procedure to improve the hardness and toughness to meet the extrusion conditions of high temperature and high pressure.Generally, during heat treatment, in order to

Some problems about hollow dies and die corrections 1.Twisting and side bending of square and round tube diesThe causes of torsion and side bending defects of aluminum extrusion profiles are mainly caused by uneven flow velocity caused by uneven metal supply.The picture below is a schematic diagram
