As a professional aluminum profile and accessories manufacturer with more than ten years of industry experience, Chengdu Zhuanchuang Aluminum can provide customers with spot wholesale and retail, customized deep processing services, complete specifications and mature technology, which can meet the aluminum profile processing needs of different industrial scenarios. This article will give you a comprehensive introduction to the relevant knowledge of industrial aluminum profile processing from three dimensions: processing type, hole location distinction, and accuracy standards.
Common Aluminum Profile Processing Methods
From raw materials to finished frames, the core processing processes of industrial aluminum profiles include cutting, drilling and tapping. The functions of each process are clear and clear:
Most standard industrial aluminum profiles are 6 meters long. Cutting means cutting the entire profile into a specified length according to the customer’s project requirements. If it is a frame with a special structure, the corners will be cut at the corresponding angle to lay a good foundation for subsequent assembly.
According to the design requirements, holes of different specifications and types are processed at the predetermined position of the profile to meet the subsequent connection and accessory installation needs. Various hole types such as through holes, threaded holes, and waist holes can be processed.
Also called tapping, internal threads are generally processed in the center hole of the profile section to facilitate subsequent screw-in installation of casters, hoofs, connectors and other accessories to ensure the stability of the connection.
The Distinction and Use of Common Aluminum Profile Processing Holes
Different types of hole locations correspond to different installation and connection requirements. The six most commonly used types of hole locations in industrial scenarios have different characteristics and uses:
The hole has a tapered design and is mainly used to install hexagon socket bolts. After processing, the bolt head can be kept flush with the surface of the profile without protruding from the surface of the profile and affecting the overall beauty of the frame. During installation, you only need to pass the hexagon socket bolt through the countersunk hole and fix it to the center hole of the end face of another profile. It is a commonly used hole type when assembling large equipment protective covers, industrial workbenches, and safety fences.
It is a hole that completely penetrates the profile. Together with the countersunk hole, it is an indispensable matching hole position in the cross connection of the profile. Its main function is to facilitate the wrench to pass through the profile and tighten the semi-round head bolts hidden in the profile groove. Through holes can be divided into two types: positioning holes and screw through holes, which are suitable for positioning and conventional connection scenarios respectively.
Specially designed for hidden connections, used to install built-in connectors. After processing, the connectors can be completely hidden inside the profile to achieve the aesthetic effect of not exposing the accessories. Most projects with high requirements for the appearance of the frame will use this type of hole.
Similar in function to built-in holes, they are also used for concealed connections inside profiles. The difference is that anchor holes are specially designed for installing anchor connection pins and can adapt to profile connection needs at different angles.
Standard internal threads are processed in the holes to facilitate direct screwing of bolts or screws. They are the basic hole type for the installation of various external accessories. Before installing casters, handles, movable hinges, joint hoofs and other accessories, threaded holes of corresponding specifications need to be processed.
They are holes that are incompletely penetrated. They are only processed at the specified depth of the profile and will not open up the entire profile. They are mostly used for the installation of aluminum profile door frame accessories. When door handles, handles, hinges and other accessories are fixed with semi-circular head bolts or self-tapping bolts, blind holes are generally processed.
Aluminum Profile Processing Accuracy Standards
Processing accuracy directly affects the smoothness of subsequent assembly and the stability of the frame structure. Chengdu Zhuanchuang Aluminum strictly follows the industry’s high standards to control processing errors:
Conventional processing control error is within ±0.5mm. For projects with higher accuracy requirements, it can be controlled within ±0.3mm to avoid installation failure due to length deviation.
All angle cutting errors are controlled within ±1°, ensuring that door frames, conveyor lines and other structures that require angles can be assembled smoothly.
All hole processing is performed strictly in accordance with the engineering drawings provided by the customer. The hole size and depth are determined according to the accessory model, and the error is controlled within a reasonable range to avoid problems such as failure to install and excessive splicing gaps, and ensure a stable and beautiful frame structure.
