Rebirth 1990: I have three golden fingers

The first company is of course Hengli Valve Company, which has a relatively high success rate and can capture Wang Hengli's wool.

If he did not start with Hengli Company, Fang Bai would have to spend more time looking for orders.

Hengli Company has a large order volume and outsources many orders.

Fang Bai came to Hengli Company, walked around the workshop, and then went to the second floor of the office building to find Wang Hengli.

This guy was smoking in the office. Fang Bai knocked on the door and was slightly surprised when he turned around and said, "Hey, Fang Bai is here."

Although Fang Bai didn't like this bald fat man, he still had to show respect on the surface. He walked in the door and said with a smile:

"Mr. Wang, business has been very good recently, and everything is full of spring."

"It's okay, it's okay."

Fang Bai shook hands with him and checked the other party's information, only to find out that this fat bald man had ruined another girl. No wonder.

He's so numb, it's true that a dog can't change himself from eating shit!

"I just walked around the workshop and saw that your company's 2-inch globe valve carbon steel body was piled up on the drilling machine and lathe. It may affect the overall delivery schedule."

"Then there's nothing we can do. We can only urge them to work overtime."

"You can outsource the processing. It doesn't cost much. The flange surface of the 2-inch stop valve is machined, and then the holes are drilled and chamfered. It only costs 15 yuan each."

"How can it be so low? The three end faces need to be turned into flange faces, and 12 holes must be drilled. It can be done for 15 yuan. As long as the requirements are met, I will outsource all the processing. Why buy the equipment myself?" Wang Hengli didn't believe it at all. Fang Bai said, "Did you get the specifications wrong? A 1-inch valve body is pretty much the same."

"That's right, 12 holes, roughness 12.5, chamfer 1..." Fang Bai himself is familiar with this product, having worked on countless orders in the previous generation.

Wang Hengli was right, the normal quotation would be at least 17 yuan.

Quotations for machining are generally based on processing time, and the price of the product is calculated based on how much it costs per hour. It is unlikely to make huge profits unless there is a special relationship or special equipment to achieve a monopoly that no one has but I have.

Generally speaking, the hourly batch processing cost = labor cost + equipment depreciation and wear + profit + tool + electricity + site fee, etc.

The main expenses are the above. In later generations, the labor cost per hour would be 20-25 yuan, but in this era, even if the wages of machine tool workers are higher, more than one yuan per working hour is enough.

Generally, ordinary 6140 truck end faces are used, and the equipment investment return can be calculated based on 3-5 years (the design life of industrial machine tools is generally 15-25 years, but the equipment investment cost must be recovered within three to five years), and the hourly depreciation fee is about 3-5 years. 5 yuan.

The rated power of the ordinary car 6140 is about 7.5KW. It is driven infrequently and consumes about 4 kilowatt hours of electricity per hour. The electricity bill standard adopts industrial electricity charges. In the 1990s, the electricity bill was higher than in later generations.

The purchase cost and energy consumption of the radial drilling machine are less than that of the conventional 6140.

Other costs are small. It is estimated that the processing cost of ordinary turning and drilling in this era is 10 yuan per hour. Taking into account factors such as taxes, repairs, and payment risks, it is profitable to quote an hourly processing quotation of more than 15 yuan. .

One line of Hengli Company (the turning and drilling time is almost the same, one car and one drill is equipped with one line) can only process two 2-inch stop valves per hour. Taking into account failures, scrap rates, etc., the machining cost of each product has been More than 15 yuan.

Fang Bai's quote is only fifteen yuan. If the quality requirements can be met and management costs are eliminated, Wang Hengli will definitely be happy to outsource the processing.

Fangbai's low quotation is mainly due to the low efficiency of various valve companies in processing valves these days.

Inefficiency is mainly due to two reasons:

First, the stop valve has a complex shape. Although Hengli Company made a tooling fixture for the end face, it was not suitable. It was not much different from the traditional clamping method, and the clamping efficiency was low.

The second point is that there are too few CNC drills now, and they all use manual drilling. The general drilling process is to first mark the line (to locate the center of the hole), punch and then drill (to prevent slipping during drilling), which is very slow. .

Hengli Company does not have technical personnel responsible for designing tooling and improving processes. It can only rely on workers to improve processes, but without an incentive system, who would be willing to do this?

It’s a thankless job that no worker wants.

As for improving efficiency, is it good for you?

Thinking too much!

As efficiency improves, the boss wants to lower the unit price. If the order quantity is small, the workers will earn less.

Fang Bai knew that the production cost of end-face clamping tools for stop valves was not high. He could also make drilling molds, eliminating the need for marking and punching.

Most industrial valves are standardized and have uniform specifications and sizes. Valves of the same category and size, fixtures and molds are universal. Not only the valves of Hengli Company can be used, but also the valves of other companies.

The tooling fixtures and drilling dies are solved, and the work efficiency is greatly improved. Each line can process 6-8 2-inch stop valves per hour.

The hourly processing fee can be charged 90-120 yuan, which can be said to be a huge profit.

As long as the order volume is sufficient, the annual profits of the three processing lines (three general lathes + three drilling machines) are higher than those of Hengli Company.

"Then I still don't believe it. How can it be so low-cost." Wang Hengli shook his head.

"Then let me take two blanks first and show them to you after processing. If possible, can you process your 2-inch stop valve for me?"

"I don't care which company you find for processing. If you have the ability to process it, I can process it for you as long as it's 15 yuan a piece."

Hearing this, Fang Bai stood up and shook hands with him again: "Okay, this is what you said. I'll go to the workshop to get the blank first."

"Go ahead, I'll wait for your news." Wang Hengli said with a nonchalant smile.

"Haha, no problem!" Fang Bai chuckled, left Wang Hengli's office, went to the workshop to find the workshop director, and then took away two blanks.

After returning home, measure the dimensions of the blank, and design the tooling fixture and drilling mold for the end face of the car.

The next morning, Fang Bai came to Jiayu Processing Factory again.

He wants to establish initial trust with his father-in-law, and then they can start a valve factory in partnership with him after the relationship is established.

The market for industrial valves is large, and profits are very high these days.

However, Fang Bai will not spend too much energy on the valve factory. In addition to making money, he also wants to make up for his father-in-law's wish. He longs to own a large valve factory. If it can be listed on the market, he will have no regrets in his life.

Fang Bai didn't want his father-in-law to know about his relationship with Qin Shuyu for the time being, at least until he was admitted to college.

“Boss Qin, how much does it cost to drill the end face of this 2-inch valve body?

The end surface roughness is 6.3 and the inner hole surface is 12.5, so the requirements are not high. "Fang Bai took out two stop valve bodies from the bag and placed them on the cement floor.

A valve body weighs several kilograms, which is quite heavy to carry.

"Is the quantity large? If the quantity is small, the unit price will be higher. Should the iron filings be mine? Who is responsible for the transportation? How long will it take to settle the payment?"

Qin Donghai asked in detail. He had experience in processing this kind of 2-inch valve body.

After thinking for a while, Fang Boluo said: "The first batch of orders will not place more than 500 valve bodies. There will be more in the future. The processing of iron filings is of course yours, and the transportation is the responsibility of the manufacturer. You can deliver the goods if you want, and freight will be charged. I will try to settle the payment within 60 days. .”

In addition to Hengli Company, he also has to look for supplies from other valve companies. His quote of 15 yuan is easy to find. His father-in-law's two machine tools are still too busy even if their efficiency has improved.

When Qin Donghai heard that it was a large batch, he was delighted and said, "It's 16 yuan, I'll make some hard-earned money right now."

According to his own situation, if the order quantity is 500, and everything goes well, the profit will be more than 3,000 yuan, and it can be completed within a month.

His average monthly profit is about 2,000 yuan. Of course he is happy to reach 3,000 yuan now.

The two discussed the price and avoided the drillers in the workshop. The OEM price is the secret of a processing factory.

"The quotation is quite reasonable. What if I can process more than 6 pieces an hour?"

"How can it be?

It's good to be able to process two in one hour. The workpiece has a complex shape and is difficult to clamp. The holes have to be drilled one by one, and both turning and drilling take half an hour. "

"That's your old method. You don't have tooling and fixtures, so the efficiency is of course slow." Fang Bai said with a smile, "Well, I'll come to you for the order, I'll provide the process and tooling, and you'll start working on two pieces of equipment. I'll give you 50 per hour. 400 yuan for 8 hours a day.

According to your traditional method, even if you work for 10 hours a day, you can earn up to 320 yuan. In fact, people also need to rest, so if you can get 250 yuan, it is too much. "

Fang Bai's algorithm made Qin Donghai a little confused.

If you calculate it this way, it is indeed more than what you make every day, and the actual profit is doubled, but you also have to do more work, and you seem to be suffering a loss.

The problem is, if it were really that efficient, 500 pieces would be finished in less than ten days.

For Fang Bai, if he can process 50 pieces a day, the processing fee is 750 yuan. After deducting the 400 yuan for his father-in-law, he will make a net profit of 350 yuan.

However, after my father-in-law knows about the new mold and tooling fixtures, he will probably have other ideas, and we will talk about it at that time.

The order is in your hands, only if you have the ability to take it.

Father and son have to settle accounts clearly, and so will future in-laws.

Seeing his father-in-law struggling, Fang Bai took out the drawing he drew last night and handed it to him: "Do you have the materials? The drill bushing part is made of No. 45 steel, 40CR is better. After processing, it must be tempered. Process these two first. The set of fixtures, materials and processing fees are all mine.

In addition, I take back the drawings after they are used up. "

After the material is tempered, it has a higher hardness and is more wear-resistant. Generally, it is processed first and then tempered, otherwise the tool will not work.

Of course, not all materials can be tempered. Low carbon equivalent cannot be tempered. For example, No. 20 steel is generally hardened by carburizing.

Qin Donghai took the drawing and looked at it briefly. Then under Fang Bai's explanation, he quickly understood what the drawing was about. He raised his thumbs up and said with a smile: "It seems to make sense, but you have to make it to know whether it can be done." It will take at least half a day, and the materials and processing fees will cost a hundred yuan in total."

"Money is a trivial matter, let's process the end face fixture first." Fang Bai said.

It costs one hundred yuan to make two sets of clamps, which is not expensive including the cost of materials. Both sets of tooling have cutting and welding processes. My father-in-law can't make any money, so he still has to spend time.

After finishing speaking, he took out a one hundred yuan note from his trouser pocket and handed it to his father-in-law.

After Qin Donghai received the money, he immediately started looking for materials for processing.
