How to quote about plastic molds, how to calculate the mold size on the plastic mold quotation form

Ask the ** person to tell the mold size.

Calculate the quantity of each material.

According to the ** of each heavy steel and the ** machined, the basic cost price is calculated.

Then consider some molding costs, management fees, etc.

Draw conclusions about the review of plastic molds.

This should be more material, manual, machine processing man-hours, and other aspects of the system**;

The elements of our company's actual mold include: material cost, design cost, bridge processing fee and profit, value-added tax, mold trial fee, packaging and transportation fee.

Among them, the size of the mold is included in the material cost. The size of the mold is estimated according to the size of the product, the number of cavities (1 cavity or more cavities), the type of mold base (2 or 3 plate molds), the product mechanism and other factors before the mold is not designed.

The difference between blow molding mold and plastic mold is quite big, and there are many places between the two, which can be understood as: spray molds for high-end products are used in chemicals, automobiles, Zai Kai instruments, household appliances, etc. In terms of materials, materials of various metals can be used, such as metals, steels, aluminum-magnesium alloys, etc.

In terms of mathematics, materials that use various metals are called metal layers, and using mathematical methods are called metal layers. In the method of using mathematics, it is necessary to pay attention to the volume of metal. The main types of plastics commonly used are as follows:

1) Substrate. Along with plastic is plastic film. The production method of plastic film is to roll polyethylene film, then coat it on the surface of plastic film, and press it into a packaging container with moisture-proof, fragrance-retaining and heat-insulation.

2) Blow molding. Also known as blow molding, it is a method of using new materials to blow the original plastic into a film as a container. Blow molding packaging is a new type of material, but its main feature is white, the surface is uneven, and it is relatively easy to make a living.

I'm just doing mold work, and I said a lot upstairs, but I didn't go into detail enough, but I have to add a few points later.

**, depending on the following factors, first, the size of the product, the shape of the simple and complex. This determines what the corresponding structure of the mold has, which is directly related to the cost of the mold.

Second, the product has requirements for size and appearance, requires precision, and has high appearance requirements, and the processing cost is not the same.

Third, the requirement for the number of mold cavities is to switch the mold once, out of several products, whether one or more at a time, this is generally not too big a product to have this item.

Fourth, the expected mold production volume, which determines what kind of material to use, is also related to the cost.

Generally speaking, the structure is simple, the requirements are not high, the material is generally general, the product is within 10cm, and the cost of the mold is about 20,000 yuan. It's hard to say the specifics, it all depends on the product.

If you have a specific product map, I can calculate the cost for you that is relatively close, but each factory will have a big disparity, because they have different requirements for profit points.

The structure of the product is also very important, this involves the cost of processing, the more complex the structure, the more expensive the processing, and the so-called management fee of some large companies, etc., just tried the following attachment can not insert a detailed calculation method, you can click on my screen name to find me can also [Sino L87,674L,O86O].
