Filter element
The filter element is divided into dry type and wet type, which are mainly used to remove impurities in the air required by the engine. The dry performance is made of paper or organic materials, while the wet filter is made of mesh wire.
Both are capable of filtering large and heavy impurities in the air and purifying the air with the synergy of the air guide vanes. The quality of the filter outer packaging on the outer packaging standard font is clear, the surface paint texture is smooth, the sealing effect is good, can protect the engine well, thus reducing the occurrence of engine inactivity due to dust accumulation. The inferior filter element is poorly made, the package font is ambiguous, the filtering effect is poor, the service life is short, and it is easy to be damaged.
Spark plug
Counterfeit spark plugs have poor electrode gaps and poor insulation properties, resulting in poor thermal conductivity and relatively low anti-conductivity. After use, they are likely to cause insufficient combustion, resulting in reduced engine power, increased fuel consumption, and overheating of the engine. It brings certain safety hazards in the car driving. How to tell the authenticity of the spark plug? Just look at the screw plug's thread for smoothness and don't tie it. You can also shake the terminal screw cap by hand, if it is firm and not loose, it is a genuine quality spark plug.
In addition, the brand name and model of the surface of the ceramic insulator coated with genuine spark plugs are clearly visible, and if the hand is easily smashed, it is a replica.
Brake pad
Brake pads are extremely difficult to distinguish between authenticity and other automotive parts, but consumers can still see a bit of eyebrows from the outer packaging and products. The genuine packaging is excellent and complete, the screws, clips and wear sensors attached to the package are well-made, the surface has no obvious scratches and bumps, and the braking effect is good. The brake performance of inferior brake pads is generally poor, there is obvious sharp friction sound when braking, and the vehicle can not be stopped due to severe heat.
Here to remind consumers that if you encounter the above situation, please go to the regular 4s shop and brand repair shop to check and replace the brake pads to avoid accidents.

Recruiting professional knowledge in a small classroom

Recruitment is also called "finding people", "hiring people", "recruiting new". In the literal sense, it is the selection activity of a subject to achieve or accomplish a certain goal or task. Recruitment, generally consists of the subject, the carrier and the object, the subject is the user, the carrier is the dissemination of information, and the object is the candidate who meets the criteria. The three are indispensable.
In terms of procedures, recruitment is usually composed of employer standards and number of people, information dissemination, communication, assessment, comparative selection, trial use, and employment. The employer formulates a recruitment plan and accepts the user in a certain way. Recruitment, as a marginal humanities science, can be divided into political recruitment, military recruitment, economic recruitment, cultural recruitment, etc. according to the field; according to the main body can be divided into government recruitment, corporate recruitment, personal recruitment; according to the implementation of recruitment, can be divided into independent Recruitment and entrusted recruitment; according to the applicant can be divided into the boss to recruit employees and employees to recruit the boss, the boss recruits the staff for mainstream recruitment, the employee recruitment boss is a non-mainstream recruitment, in July 2009, an engineer appeared in Shanghai, China, the recruitment of the boss The situation, although it succeeded in the operation and ending, filled the gap in the "recruitment market" dual-track system, eased the psychology of the working group, caused media attention, and provoked strong repercussions in the society, but it still belongs to the non-mainstream in the model. Belong to a special individual case.
The executor of the recruitment may be the personnel management department of the employer, or the agent or agency, such as a headhunting company or a talent exchange.
The synonym for recruitment is “introduction”. For the recruitment of general talents, it is generally expressed by “recruitment”; for the selection of senior talents or special talents, it is usually described by “introduction”.
Enterprise recruitment refers to the process of selecting and attracting those who have the ability and interest to serve in the enterprise according to the requirements of human resources planning and job analysis for the needs of development, and select the appropriate personnel to hire.
It refers to the activities of the employer through the formulation of the recruitment plan and the admission of new employees through certain methods. It is generally the responsibility of the personnel department of the company or the human resources management department.
The source and channel of recruitment should be selected according to the characteristics of the unit. Each unit has its own unique side, and the requirements for employees are also different. Therefore, successful recruitment must meet the requirements of the organization itself. In addition, due to the different types of jobs, the sources and methods of recruitment are not the same. Each unit should decide according to its own actual conditions, what methods and methods should be adopted, recruit personnel of different positions, and provide outstanding talents for the units in a timely manner.
There is also the use of headhunting recruitment, using the skills of headhunting recruitment, corresponding to senior talents and cutting-edge talents, often difficult to obtain with traditional channels, but such talents have a very important role in the organization. Therefore, when recruiting senior talents, some organizations have gradually become accustomed to relying on headhunting companies to operate. However, the effects of different organizations using headhunting companies are quite different. Therefore, the first thing an organization needs to do when looking for a high-level talent is to accurately describe job responsibilities and qualifications on the basis of standard processes.

Recruiting professional knowledge in a small classroom

Recruitment refers to recruiting and hiring workers and staff to work. Under the capitalist system, recruiting workers adopts the principle of free competition. The recruitment of employees in China is based on the needs of the national production plan. The state adheres to the principle of unified labor deployment. No unit can recruit employees privately. In 1951, the Ministry of Labor announced the "Interim Provisions on Recruiting Employees in Different Places", stipulating that recruiting employees must abide by certain systems and handle certain procedures. Recruiters and recruits should conclude labor contracts, and pay wages, benefits, working hours, and probationary periods. As well as the travel and tolls for the distant people, the home payment, etc., and the local labor administrative agency for the record. In recent years, the recruitment of workers has basically adopted the above methods. Some stipulated candidates must be subject to business assessment, interview, and merit-based admission according to the needs. After approval by the higher authorities, they will be officially hired after half a year.
Employee recruitment, referred to as recruitment, refers to the general term of “recruitment” and “hiring”, and find suitable candidates for the positions of enterprises and institutions. Selection refers to the process of selecting qualified persons to fill job vacancies by scientific personnel assessment methods.
Recruitment is the organization of activities to acquire human resources through the labor or talent market. It is based on the needs of its own development, in accordance with market rules and the requirements of the organization's human resources planning, through various feasible means and media, to release recruitment information to the target public, and to recruit and hire the organization's manpower according to certain standards. The whole process of resources. As an important part of human resource management, personnel recruitment involves many aspects such as planning, approach, organization and implementation. It is the first link for the organization to obtain human resources and the basis for personnel selection.
The most direct purpose of recruitment is to make up for the shortage of human resources in the enterprise, which is the premise of recruitment. Specifically, corporate recruitment generally stems from the following purposes:
(1) The total supply of human resources of the enterprise today cannot meet the total mission objectives of the enterprise or each position (ie, planned total business volume or planned total output), and needs to be supplemented;
(2) Job vacancies caused by the normal replacement of mobile personnel in enterprises or positions;
(3) The possible demand for human resources due to changes in the production technology level or management methods of enterprises or positions;
(4) Meet the needs of personnel required for new planning or new business development.
When the human resources of the enterprise are absolutely or relatively insufficient, the enterprise has many solutions. There are ways to improve efficiency, such as extending employee working hours or increasing workload, training or improving technology to improve employee productivity.
Of course, recruitment and recruitment require higher costs including finding, interviewing, paying agency fees, and relocating and training new employees. Therefore, companies should try to work overtime and increase temporary work before choosing a job.

Injection mold design is good, please remember in the 17th National Congress (1)

The mold industry is a basic industry in the manufacturing industry and the basis for the transformation of technological achievements. At the same time, it is an important field of high-tech industries. It is called the “magnetic industry” in the industrialized countries such as Europe and the United States.
The American industry believes that "the mold industry is the cornerstone of American industry"; Germany considers it to be a "key industry" in all industries; the Japan Die Association also believes that "the mold is the driving force for the prosperity and prosperity of society" and "the whole industrial development." The secret of "the driving force behind entering a wealthy society."
First, the mold opening direction and parting line
Each injection molding product must first determine its mold opening direction and parting line at the beginning of the design to ensure that the core slider mechanism is minimized and the influence of the parting line on the appearance is eliminated.
1. After the mold opening direction is determined, the reinforcing ribs, snaps, protrusions and other structures of the product are designed to be consistent with the mold opening direction as much as possible to avoid the core pulling to reduce the seam line and prolong the life of the mold.
2. After the mold opening direction is determined, the appropriate parting line can be selected to avoid the reverse buckle in the mold opening direction to improve the appearance and performance.
Second, the draft angle
1. Appropriate drafting angle can avoid product pulling (drawing). The smooth surface of the draft should be ≥ 0.5 degrees, the fine grain (sand surface) surface is greater than 1 degree, and the rough grain surface is greater than 1.5 degrees.
2, the appropriate draft angle can avoid product top injuries, such as white, top deformation, burst.
3, deep cavity structure product design when the outer surface slope should be greater than the inner surface slope as much as possible to ensure that the mold core is not biased during injection, to obtain a uniform product wall thickness, and to ensure the material strength of the product opening.
Third, the product wall thickness
1, all kinds of plastics have a certain wall thickness range, generally 0.5 ~ 4mm, when the wall thickness exceeds 4mm, it will cause the cooling time is too long, resulting in shrinkage and other issues, should consider changing the product structure.
2. Uneven wall thickness will cause the surface to shrink.
3. Uneven wall thickness can cause pores and weld lines.
Fourth, the reinforcement
1. Reasonable application of reinforcing ribs can increase product rigidity and reduce deformation.
2. The thickness of the reinforcing ribs must be ≤ (0.5 ~ 0.7) T product wall thickness, otherwise the surface will shrink.
3. The slope of the rib should be greater than 1.5° to avoid top injury.
Five, rounded corners
1. If the fillet is too small, it may cause stress concentration of the product, resulting in cracking of the product.
2. Too small a fillet may cause stress concentration in the mold cavity, resulting in cracking of the cavity.
3, set a reasonable rounded corners, can also improve the processing technology of the mold, such as the cavity can be directly processed with R knife milling, and avoid low-efficiency electrical processing.
4. Different rounded corners may cause the movement of the parting line. Different rounding or clearing angle should be selected according to the actual situation.
Six, the hole
1, the shape of the hole should be as simple as possible, generally take a round shape.
2. The axial direction of the hole is the same as the direction of the mold opening, and the core can be avoided.
3. When the aspect ratio of the hole is greater than 2, the draft angle should be set. The diameter of the hole at this time should be calculated according to the size of the small diameter (the largest physical size).
4. The aspect ratio of blind holes is generally not more than 4. Anti-hole punching
5. The distance between the hole and the edge of the product is generally greater than the aperture size.
7. The core of the injection mold, the slider mechanism and avoidance
1. When the plastic parts cannot be demoulded smoothly according to the mold opening direction, the core pulling slider mechanism should be designed. The slider of the core pulling mechanism can form a complicated product structure, but it is easy to cause defects such as seam stitching and shrinkage of the product, and increase the cost of the mold to shorten the life of the mold.
2. When designing injection molding products, if there is no special requirement, try to avoid the core structure. For example, the direction of the hole axis and the direction of the rib is changed to the mold opening direction, and the cavity core is used to penetrate.
Eight, one hinge
1. Using the toughness of PP material, the hinge can be designed to be integrated with the product.
2. The size of the film as a hinge should be less than 0.5 mm and kept uniform.
3. When molding an integral hinge, the gate can only be designed on one side of the hinge.
Nine, inserts
1. Inserting inserts into the injection molding product can increase local strength, hardness, dimensional accuracy and set small threaded holes (shafts) to meet various special needs. At the same time, it will increase product costs.
2, the insert is generally copper, but also other metal or plastic parts.
3. The part of the insert embedded in the plastic shall be designed to prevent rotation and pull out. Such as: knurling, holes, bending, flattening, shoulders and so on.
4. The plastic around the insert should be properly thickened to prevent stress cracking of the plastic part.
5. When designing the insert, the positioning method (hole, pin, magnetic) in the mold should be fully considered.
