(3) Die casting requires the placement of inserts.
Only a few inserts are installed, and each installation fee is added with 0.5 yuan (which increases the working procedure and reduces the production efficiency).
(4) The shape is complex and difficult to shape.
Depending on the situation, a compound fee of 10~50% can be added (on the basis of the basic customs fee) (die cost increases, production difficulty, quality control difficulty, die failure rate increases and production efficiency decreases).
3. 1.4 Specific requirements for the price increase level (see Schedule 4)

3.2 The processing price of die castings produced by contract packaging shall be calculated according to Formula (2).
Formula (2):
Processing price = basic clamping fee+melting fee+price increase of complex parts+price increase of specific parts+material price of die-casting parts.
3.2. 1 Basic mold closing fee, smelting fee, price increase for complex parts and price increase for parts with special requirements shall be implemented according to 3. 1.2, 3. 1.3, 3. 1.4.
3.2.2 The price level of die casting materials shall be calculated according to the following formula (3).
Formula (3):
Die casting material price = material unit price × material consumption quota+management fee and profit.
3.2.2. 1 self-matching gold
The unit price of materials is A when ordering. . The market price of aluminum and 0 # zinc plus the processing fee of its alloy aluminum (different zinc and aluminum alloys charge different processing fees), but the unit price of copper alloy materials is based on the market price of 1 # copper and 0 # zinc plus the processing fee, and the market price of magnesium plus the processing fee.
3.2.2.2 buys standard alloy ingots.
The unit price of materials is based on the price of alloy ingots at the time of ordering.
3.2.2.3 material consumption quota is calculated according to formula (4).
Formula (4):
Material consumption quota = die-casting net weight+(die-casting net weight+casting system weight) × loss rate.
1. The weight of gating system is 0.2~0.8 of the net weight of die casting (depending on the workpiece).
2. Loss rate: 7% for copper alloy castings, 5% for aluminum alloy castings, 6% for zinc alloy castings and 3% for magnesium alloy castings.
3.2.2.4's management fee and profit are calculated at about 8% of the cost of die-casting materials. (According to the casting payment time)
The processing price of magnesium alloy die casting is 30% higher than that of aluminum-zinc alloy die casting.
5. The processing price of die casting stipulated in Article 3 of the present Measures does not include the cost of die trial. If the mold provided by the entrusting party needs to be tested, both parties shall negotiate the test fee according to the complexity of the mold.
6. The surface of die casting needs sandblasting, shot blasting, surface coating, passivation and electroplating, and the production of tools made by manufacturers needs to increase the corresponding processing costs.
7. If the entrusting party requires the test bar to undergo physical and chemical inspection and other special inspection items according to the furnace and parts pouring, the corresponding expenses will be increased separately.
8. Die castings that need metal cutting (including large parts that cut off the waste edge of the gate) are charged according to the actual consumption per hour of the machine tool.
If the mold is produced by the entrusting party, in the production process, if the mold needs to be repaired, the minor repair costs shall be borne by the manufacturer, and the major and medium repair costs shall be charged to the entrusting party according to the actual situation.
10 the entrusting party has provided its own die-casting mold, but its design is flawed, which makes the process difficult, so it is necessary to increase the cost of lost time (or the entrusting party bears the cost of modifying the mold).
1 1 For die-casting parts that need station equipment or packaging and transportation, the expenses for station equipment and packaging and packaging shall be borne by the entrusting party.
12 The processing price in this price is allowed to fluctuate by 20%.
13 For users who have long-term fixed-point cooperative relations and have large orders, preferential prices will be implemented through negotiation between both parties.
14 when the entrusting party requires the use of non-die-casting alloy to produce die-casting, the processing price of die-casting can rise by 20%.
15 when the client puts forward special technological requirements such as heat treatment for the produced die castings, the processing price of the die castings can rise several times.
16 in addition, all factors affecting production efficiency and production cost should be considered, and the price should fluctuate appropriately. If the wall thickness of die casting is thick and the mold opening time is long, which reduces the production efficiency, the price should rise appropriately; The inevitable large core-pulling in mold design makes the spraying manipulator unable to work normally, which requires manual spraying, which requires higher operation level and proficiency of workers, reduces production efficiency and increases the price appropriately. The price of raw materials in each period is constantly changing. The supply and demand sides should agree that the price of raw materials will fluctuate within a certain range and the price of castings will remain unchanged. The excess part needs to be adjusted in time, otherwise, the price of castings will be calculated dynamically according to the price of raw materials in each period. As well as the increase in labor costs and the changes in the prices of various raw and auxiliary materials.
17 dear friends, because my brother is a hardware maker, and I just started this industry, and I don't know much about die casting. Please help me to say what the following means.

What kind of beer are there above 180T and 250T? What do these mean? I hope you can tell me,
