How to choose a high quality sheet metal fabricator

1. Look at reputation:

When choosing a sheet metal processing manufacturer, you first need to understand whether the manufacturer's reputation in the industry is good, if there is a good reputation, then whether it is in the quality of the product, or after-sales service will be more guaranteed, otherwise, it is not recommended to choose.

2. Look at customer cases.

If the manufacturer has a wealth of sheet metal processing cases, then it is bound to accumulate rich experience, so it is much more reliable to have no customer cases.

3. Look at the manufacturer's service attitude.

Service is an intangible thing, but it is also a representative of the soft power of the manufacturer, is another image display of the manufacturer, for consumers, the manufacturer's service is good, the more timely communication with the manufacturer, timely response to the problems in processing, to solve the trouble, but if the manufacturer's service attitude is not good, not only directly affect the use, but also increase the cost of the enterprise.

High-quality processing plants have the following conditions 1: there is enough equipment configuration, that is, the so-called hardware is complete 2: there are enough staffing, there are technicians, quality inspectors, and other technical personnel of the software configuration.

3: The plant area is large enough to stack the finished products, so that the finished products are not easy to be damaged. 4:

Have your own logistics staff, so as to avoid losses on the way to delivery. Of course, few sheet metal factories have the above conditions.

First of all, it is necessary to see whether the production equipment of the factory is of high quality;

secondly, it depends on the partner of the factory;

The last thing is to look at the process;

Of course, the important thing is to look at the price.

Shenyang Xinyu innovative technology, specializing in customized sheet metal processing, non-standard sheet metal processing, etc.

New Domain Innovation Factory.

That's what our company does.

The sheet metal factory processes sheet metal parts, and the treatment depends on the ability. Sheet metal processing includes traditional cutting and cutting, blanking processing, bending forming and other methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operation methods, as well as new stamping technology and new processes. The processing of metal sheets of parts is called sheet metal processing.

Sheet metal processing is called sheet metal processing. For example, the use of plates to make chimneys, iron drums, oil tanks, ventilation pipes, elbow heads, round places, funnel shapes, etc., the main processes are shearing, bending buckles, bending forming, welding, riveting, etc., which require certain geometric knowledge.

Sheet metal parts are sheet metal fittings, that is, parts that can be processed by stamping, bending, stretching and other means, and a general definition is the parts whose thickness remains unchanged during the processing process. The corresponding parts are castings, forgings, machined parts, etc.

Commonly used materials:

1. Galvanized steel plate SECC

The substrate of SECC is a general cold-rolled steel coil, which becomes an electrogalvanized product after degreasing, pickling, electroplating and various post-treatment processes in the continuous electrogalvanizing production line. SECC not only has the mechanical properties and similar machinability of general cold-rolled steel sheets, but also has superior corrosion resistance and decorative appearance. It has great competition and substitution in the market of electronic products, home appliances and furniture.

For example, SECC is commonly used in computer cases.

2. Ordinary cold-rolled plate SPCC

SPCC refers to the continuous rolling of steel ingots into steel plate coils or sheets of the required thickness through a cold rolling mill. The surface of SPCC does not have any protection, and it is easy to be oxidized when exposed to air, especially in a humid environment, the oxidation rate is accelerated, and dark red rust appears.

3. Hot-dip galvanized steel plate SGCC

Hot-dip galvanized steel coil refers to the semi-finished product after hot-rolled pickling or cold rolling, which is cleaned, annealed, and immersed in a molten zinc tank with a temperature of about 460 °C, and the steel sheet is coated with a zinc layer, and then quenched and tempered and chemically treated. SGCC material is harder than SECC material, poor ductility (avoid deep pumping design), thicker zinc layer, and poor weldability.

4. Stainless steel SUS304

One of the most widely used stainless steels, it is more corrosion-resistant, heat-resistant, and has very good mechanical properties than CR (chromium) steels because of its Ni (nickel) content, no heat treatment hardening, and no elasticity.

5. Stainless steel SUS301

The content of CR (chromium) is lower than that of SUS304, and the corrosion resistance is poor, but it can obtain good tensile force and hardness in stamping after cold working, and has good elasticity, which is mostly used for shrapnel springs and anti-EMI.

The sheet metal factory is used to process sheet metal parts.

Sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing, punching, lamination, folding, riveting, splicing, forming (such as automobile body) and so on. Its distinctive feature is that the thickness of the same part is the same.

Generally speaking, the basic equipment of sheet metal process includes shear machine, CNC punching machine, laser, plasma, water jet cutting machine, bending machine and various auxiliary equipment such as: uncoiler, leveling machine, deburring machine, spot welding machine, etc.

Generally, the four most important steps of the sheet metal process are shearing, punching, rolling, welding, surface treatment, etc.

Sheet metal factories generally want sheet metal electric welding to be able to not just weld, now sheet metal factories generally do not use electric welding, with 2 welding treatment apprentices 1500 This is with your skills and work experience are president.

The salary is different in different regions, and in Ningbo, a better welder is 4000-6000 yuan a month.

The sheet metal factory mainly does sheet metal parts such as chassis and cabinets, including argon arc welding, electric welding, gas shielded welding, etc.

1. Automobile sheet metal is a job in automobile repair.

2. Mainly responsible for the body repair work after the collision of the car.

3. The general workflow is 1: body disassembly and assembly 2: body correction 3: body repair.

Equipment needed for sheet metal processing:1. Welding equipment: mainly for butt welding machine and argon arc welding machine.

3. Processing machinery and equipment: bending machine, plate cutting machine, plate rolling machine and punching machine, etc.

4. Other equipment: air compressor, grinder, and some painting equipment.

Generally, sheet metal factories have shearing machines, high-speed punching machines, bending machines, welding machines, plus some common polishing and polishing machines, such as cutting, grinding, polishing, etc. The actual choice is determined according to the manufacturing of goods to be made. High-precision sheet metal processing requires CNC machine tools, and ordinary sheet metal equipment that requires too low.

Processing steps: The processing steps of the processed parts in the sheet metal workshop are: product pre-test, product processing trial production and product batch production. In the process of product processing and trial production, we should communicate with the customer in a timely manner, and then carry out mass production of the product after obtaining the evaluation of the corresponding processing.

Laser perforation technology is the earliest laser technology to realize practical application in laser material processing technology. Laser drilling in the sheet metal workshop generally uses pulsed laser, with high energy density and short time, which can process 1 m hole, especially suitable for processing small holes with a certain angle and thinner material, and also suitable for processing deep holes and micro holes on parts with high strength and hardness or brittle and soft materials.
