Opportunities are still hard to find in Erdos


As a newcomer to the heavy truck industry, Changan ChongQing has been regarded by some people in the industry as lacking the ability to develop the national market and has only been able to live in Shanxi Province. However, in Erdos, the reporter discovered the dealer of Changan Heavy Duty Truck. As an important heavy-duty regional market, heavy-duty companies in Ordos battles almost all major domestic companies. Although there is great demand and many opportunities, in Ordos, can heavy truck "new recruits" share such a sales feast?

New brand is hard to stand on

“We talked about this project early this year. We will begin selling Chang'an heavy trucks in April and May, but sales have not yet risen.” Sun Jun, Deputy General Manager of Changchun Chongqi, Jindu Port, Ordos City, told reporters: “The reasons are many reasons. , It takes time for the new brand to be approved by the user."

Indeed, for any mature market, it is very difficult for “new recruits” to win the ideal market share at the first time, not to mention the heavy-duty market where local demand is different and users prefer different ones. It is not only difficult for Changan Heavy-Duty Trucks and other heavy-duty trucks to enter the initial stage of the "new recruits". Even many old heavy-duty truck companies have encountered "Waterloo" in the Ordos market. An unnamed heavy-duty truck dealer stated: “Before a certain heavy truck company made technical upgrades and product platforms changed, the company could not restore its market share in Ordos for a long time.”

It can be seen that the Erdos heavy truck market does not exclude the entry of new brands, but the acceptance of new brands is indeed not high. As a result, companies such as FAW Jiefang and Dongfeng Commercial Vehicles in the field of road transport, China National Heavy Duty Truck, Shaanxi Heavy Duty Truck and other companies in the field of engineering vehicles are not difficult to understand the strength. On the one hand, it is a booming market demand, on the other hand, it is a difficult entry barrier, which makes the heavy truck “recruits” love and hate the Ordos market. "It is precisely because of this that some companies have adopted some aggressive market operation modes and have achieved certain results in the short term, but they have also disrupted the normal market order," said heavy truck dealers who declined to be named.

New products difficult to promote

Not only is it difficult for new brands to enter the market, but the promotion of new products in Ordos has also encountered resistance. According to Sun Jun, the Changan heavy trucks sold by the company are all diesel vehicles instead of the natural gas vehicles that Changan Heavy-duty trucks promoted at this year's Beijing International Auto Show.

“Arguably, Erdos is known for its “elevated brilliance”, which includes abundant natural gas resources.” Sun Jun said: “In the Ordos market, natural gas trucks are difficult for users to accept.”

The replacement products of some companies also need to undergo two to three years of market cultivation to recover. This is of course due to the laws of the market, but it has brought about some inconvenience to the Erdos heavy truck market which is in a period of vigorous development. For example, if a new model of a company's focus on market changes is delayed due to promotion difficulties, it may result in the market still focusing on old models, and the structural adjustment of models will face greater difficulties.

Most of the taxis in Dongsheng District of Ordos have been refitted, usually dual-fuel vehicles, which also provides ideas for the promotion of natural gas heavy trucks. A person in charge of a special vehicle company said: “Users have doubts about the power of natural gas trucks. We do not think it is a big problem. However, we believe that the use of dual fuels is closer to market demand. On the one hand, this model can be used to a greater extent. The local gas source advantage can be utilized; on the other hand, the dual fuel design can also use different drive fuels depending on the specific road conditions to achieve the goal of reducing emissions and reducing fuel consumption as much as possible.”

For the market "sword to walk forward"

Up-and-coming youngsters must grab the site, hindering the promotion of new products and new brands; existing market leaders must consolidate their position and benefit from this inertia in sales. In order to compete for market share, many heavy-duty "recruits" companies have devoted themselves to Ordos. "Some companies are looking for a price war, and some companies provide financial services. In short, as long as they can enter the market as soon as possible and can stabilize their share, it can be said to be 'all show supernatural power'," said the heavy truck dealer who declined to be named.

“Before, there were more than 90 dealers with heavy-duty trucks in Ordos, and the chaotic market order was evident.” The distributor further introduced: “It is precisely because of the inertia of the heavy truck market in Erdos that the heavy truck brands The level of acceptance in the user's mind is different, leading to disorderly brand competition and burying hidden dangers in the heavy truck market."

According to the dealer’s analysis, after the “prosperity” of good sales but insufficient profits, the heavy-duty truck market in Ordos may face a “big reshuffle” in recent years, especially the layout of outlets is too unreasonable and the marketing methods are too utilitarian. Dealers are most at risk. He said: “The Erdos heavy truck market is currently in a period of rapid development, and it is very likely that it will enter the structural adjustment period in the near future. If the heavy truck 'recruits' can be deeply cultivated, they will not necessarily have no chance.”

CNC Milling

In general, computer numerical control milling machine (CNC) machining is a deductive manufacturing technique that programs 3-axis linkage, complex to 5-axis linkage, drives milling cutters to remove layers from solid blocks called blanks to produce finished parts. CNC milling is one of the main types of CNC Machining, which uses cutting tools that rotate at a speed of several thousand to tens of thousands of revolutions per minute (RPM) to precisely remove materials to obtain parts with complex surfaces. In addition to milling, CNC machining is also equipped with drills, boring tools, thread cutters and other tools to complete different part features at once. CNC machining produces parts based on a computer-aided design (CAD) model that is sent to a CNC machine through computer-aided manufacturing (CAM) software.

CNC Machining centers developed from CNC milling machines. The biggest difference compare to CNC milling machines is that the machining center has the ability to automatically exchange machining tools, by installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changing device in a single clamping device to achieve a variety of machining functions.

CNC milling accuracy

CNC milling centers and high-Precision Machining centers. Ordinary machining center, resolution of 1μm, maximum feed speed of 15 ~ 25m / min, positioning accuracy of about 0μm. High-precision machining center, resolution of 0.1μm, maximum feed speed of 15 ~ 100m / min, positioning accuracy of about 2μm. Between 2 and 10 μm, with a ± 5 μm more, can be called precision grade. FCE equipped with different grade and different size CNC milling center. Take in to account into both economic and quality in parallel.

CNC Finishing surface treatment

Post-processing is the final step in the CNC machining process. In a quick guide, we offer a lot of surface treatments to complete your final parts and get them to meet strict specific requirements. It should be noted that in CNC machining, post-processing is in optional, as the quality of the machined parts is already very high.

Anodized

The anodizing process allows the part to obtain excellent corrosion resistance, increasing the hardness and wear resistance of the surface. Anodizing is also the most common pre-painting treatment, which can help the painted surface to obtain good adhesion. We typically apply two types of anodizing in our production: Type II, corrosion resistant; Type III is thicker, adding a layer of wear resistance. Both anodizing processes can achieve a variety of color effects.

Polishing

Grinding polish, it offers the fastest turnaround parts and does not require post-processing. The surface finish of the grinding part is equivalent to 125 um in Ra, and the requirements can be increased to 63, 32 or 16 um Ra. Minor tool marks may still be visible on the last part.

Powder coatings

Powder Coating is thermoplastic powder spraying directly on the processed part. The sprayed parts are then baked in an oven to form a durable, abrasion- and corrosion-resistant plastic coating. In the powder coating process, its color, brightness, surface roughness can be customized.

Shot blasting

Shot peening is the high-speed spraying of beads of different hardnesses and sizes onto the surface of the part. To get different textures and brightness of the surface. Since the surface has been hit by similar forging beads, the hardness and wear resistance of the surface have also been enhanced.

Design of CNC machining

CNC machining is a universal machining process, especially parts that can be cut and machined can be achieved through CNC, from simple shape shapes to complex curved structures. However, as with every manufacturing technique, CNC machining has some design limitations. We break them down as follows to ensure that your products are optimally designed to better fit the CNC machining process.

General Tolerance

When designing parts, the size of each part is different according to the application environment, working conditions, etc., and the requirements for the machining accuracy of the workpiece are also different. Although CNC machining can achieve very high machining accuracy, we should also be aware that demanding machining accuracy and accuracy (strict product tolerances) usually mean Longer production times and higher costs. If a specific tolerance is not specified in the product design, we recommend choosing at the following levels.

The highest precision of our equipment is 0.001, and the recommended most precise machining requirements do not exceed +/-0.005mm

Interior angle

All internal vertical edges of our products need to have rounded corners instead of right angles. This is because the tools used in CNC milling are cylindrical, which means they cannot produce inner right-angled edges. The fillet required by this process is called the inner corner fillet. When designing parts, the larger the inner corner fillet, the more efficient the production process. Because of the larger fillets, larger diameter milling cutters can be used to increase milling speed, and fewer swaps can be made to improve accuracy.

Undercut

Undercut cannot be machined with standard milling cutters, so the use of retract slots for parts should be avoided when designing CNC machined parts. In particular, for non-standard inner contour shapes, customized machining tools are required, which will greatly increase processing time and costs. Secondly, if undercut can not be avoided, due to the limited length of cnc tools, the undercut can not be too deep. If they are too deep or the location is difficult to reach, they will not be able to be produced because the CNC tool cannot reach the machining location.

Chamber wall thickness

CNC machining requires your part design to meet minimum wall thickness requirements. In general, it is recommended to choose the thickest possible and avoid very thin or characteristic walls. This is because CNC tools processing thin-walled parts will cause vibration deformation, which may cause interruptions or damage, and the size is out of specification. The standard minimum wall thickness for CNC machined metals is 0.030" (0.76 mm) and for plastics is 0.060" (1.5 mm).

Thread

When designing parts, it is useful to choose the largest possible thread size because smaller taps have a higher risk of breaking during production. If possible, avoid using deep hole threads as they lead to higher production costs, especially when custom tools are required.

Metal

In principle, materials with high hardness are easier to process because better processing accuracy can be obtained, but they are limited by the hardness of processing tools, so the hardness of the generally recommended parts is 8 ~ 60HRC, and for metal materials, the hardness is greater than stainless steel Followed by cast iron, followed by copper, and finally aluminum, while the processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials. Fast production time.

Polymer

Although CNC can process thermoplastics, the material properties of polymers still have many difficulties for CNC processing. First, due to poor thermal conductivity, many thermoplastics melt or bend when in contact with CNC milling machines or drill bits. Secondly, the processing of plastics, because the hardness is low, the size accuracy caused by the knife during product clamping and processing is not high. For those parts that do not have special requirements for the strength and hardness of the metal, thermoplastics can provide a cheaper alternative.

Cost optimization of machined products

Simplify product design

Simplifying product design while taking into account functionality usually saves production time and reduces production costs. Because the manufacture of complex structures and surfaces often requires complex longer passes, more layering to obtain the same fine contour quality. This means higher production costs.

Reduce cutter changes

Using the same milling machine machining features, larger and same internal fillets, can reduce the number of tools used to reduce machining time. For example, if a workpiece needs a 10mm end face milling cutter to process some features, it also needs a spherical milling cutter to process a curved surface, and a 2mm milling cutter to process a fine groove, which will require repeated tool changes and reduce the machining efficiency

Proper material selection

The choice of raw material for machining can have a significant impact on production time and costs for CNC machining. If possible, choose a material with good processability, such as brass or aluminum. For those applications that do not require metal hardness and strength, CNC machining of engineering plastics like PMMA and ABS also helps to reduce costs because the material blank is cheaper, and the processing efficiency is higher.

Tolerance and wall thickness

Higher tolerances and thinner wall thicknesses also increase THE CORRESPONDING CNC machining costs, as it takes time to achieve higher precision cutting. If your product or component can accept a larger size range, choose a lower tolerance to reduce production time and costs. The same is true for wall thickness: a larger wall thickness margin should be chosen.

Choice of surface treatment

Surface treatment is often the final stage of the CNC machining process, which can also affect the cost of your entire project. Choosing less surface treatment for your part or product can lead to better time and cost efficiency. FCE can recommend to you how to optimize the surface treatment to balance the conflict between cost and quality according to your final needs.
