Do children s chair molds need to be produced with multi tonnage injection molding machines?

DKM350T will do. It is best to have specific product data.

PVC material is a kind of plastic decorative material, is the abbreviation of polyvinyl chloride material, PVC (polyvinylchloride, referred to as PVC) resin is a thermoplastic polymer polymer polymerized by vinylchloridemonomer (VCM). It is made of polyvinyl chloride resin as the main raw material, adding an appropriate amount of anti-aging agent, modifier, etc., through mixing, calendering, vacuum blister and other processes. PVC is an amorphous polymer containing microcrystals with a crystallinity of 5%-10% (melting point 175 degrees).

The physical energy of PVC, such as molecular weight, crystallinity, and softening point, varies with the polymerization reaction conditions (temperature). PVC resin plastic is made by plasticizing and molding with a variety of additives such as stabilizers, plasticizers, fillers, colorants and modifiers. PVC material has the characteristics of light weight, heat insulation, heat preservation, moisture-proof, flame retardant, and easy construction.

There are many specifications, colors, patterns, and they are highly decorative, and are widely used in production and life. For example, PVC water pipes, PVC plastic doors and windows, as well as plastic toys containing PVC, wires and cables. Due to its harm to the human body, Europe, Japan, South Korea and other countries have imposed restrictions on products using PVC as raw materials.

The outstanding advantages of general PVC resin plastic products are flame retardant, wear-resistant, chemical corrosion-resistant, low gas and water vapor, and good leakage. In addition, comprehensive mechanical energy, product transparency, electrical insulation, heat insulation, sound reduction, shock absorption, is the most superior universal material. The defect is that it is thermally stable and has poor impact resistance, and it is easy to produce brittleness during the use of both hard and soft PVC.

Generally, PVC contains bis(2-ethylhexyl) adipate (DEHA) plasticizer that is not allowed to be used by relevant national standards, and DEHA is easy to release at high temperatures (more than 100 degrees Celsius), which is harmful to health after contact with the human body. Because PVC is a hard plastic, to make it soft, a large amount of plasticizer must be added, and the plasticizer is easily released in a heated environment. If DEHA is used, it can interfere with the body's endocrine system, causing breast cancer in women, birth defects in newborns, decreased sperm count in men, and even mental illness.

Can it be, as long as it can be installed, it is just a big horse-drawn trolley, a large injection molding machine, the power consumed is large, the action of the machine tool is slow, the production efficiency is low, and the cost accounting is not worth it. However, it can still be used for temporary emergencies.

Yes, but just be careful.

The main thing is to look at the amount of injection, how many molds are out, plus nozzle material, how much is needed for a total injection volume, and then choose the tonnage of the injection molding machine.

At least on the mold pressing plate, as well as the size of the product, the injection molding machine has instructions.

Thank you for the reply, I still don't understand.

Ringing injection molding machine. There is a mark on the rear template, the maximum and minimum mold thickness, and you know the inner distance of the guide pillar of the injection molding machine, you will know your mold, and you want to put several large machines.

I think it is difficult to convert, but the process can be used as a reference to each other, such as the amount of pressure, speed, back pressure, glue drawing, etc., the size of the barrel of different injection molding machines is different, which is the key to not converting. The adjustment machine is a highly experienced job, not like a mathematical formula can be deduced, its process conversion is basically meaningless.

This requires experience in adjustment, and it can't be converted as you said, different models have different configurations, different model parameters are different, pressure, flow, are not the same, so it can't be converted!

Why do you want to tell you about the confidential and say that it is inconvenient.

The folding stool injection molding machine can be done, and the size and weight of each piece of each stool must be used to determine the size of the injection molding machine.

Weigh the (maximum) weight of a single piece of the sample, the injection volume of the injection machine is greater than about one-third of the weight of a single piece, and consider whether the spacing of the guide pillars can be put into the mold.

Small stools can be produced with a 280-ton machine from Zhejiang Shenda.

I don't know how big the machine is, the mold should be between 3-4, if you are in Wenzhou, Zhejiang, you can find someone to help you.

How much you want to invest is the key. The mold program is different, and so is the **. There is also a big difference between the domestic and imported brands of injection molding machines.

The general mold structure of the hanger is very large, but it is relatively simple, and the structure of the mold is very simple when the mold is out of 2, but the mold base is large. **Not high, I estimate that it is about 20,000, and you don't want to buy an injection molding machine, how much does it cost, raw material pp

The material is good, the general plastic hangers are produced out of PP materials, and they can be produced after 2 times of material mixing, and the ** of PP raw materials is also very cheap, about 200 yuan a pack, and the material you produce can continue to ** in the production, outsourcing processing is good, and you can't pack a few dollars for mold materials.

I can help you with the whole process.

It is estimated that the tonnage of the injection molding machine will be between 250-350, and the price of the mold will be more than 30,000 yuan.

The raw material used is PE, which is cheap.

According to the grammage of the hanger to calculate the reference to this, it should be easy to solve, the equipment and molds are estimated at 150,000 can start production, excluding materials.
