Custom plastic manufacturing is a high-tech process that allows the production of plastic products with a wide range of applications.

Why custom plastic parts manufacturers use injection molding technology?

We use plastics for various purposes.  custom plastic parts manufacturers focus on injection molding among plastic processing. Similarly, they explain:

1. what processing methods there are?
2. what characteristics they have?
3. and what to pay attention to?

The injection molding method mainly comprises a step of plasticizing a resin by heating. A step of injecting a plasticized resin into a mold at high pressure.

custom plastic parts manufacturers Molding procedure

（1）カスタムプラスチック部品メーカーの send the pellets falling from the material feeder by rotating the screw in the cylinder.
(2) they plasticize pellets by the heater in the cylinder. And accumulated in the front part of the molding machine by the rotation of the screw.
(3) They insert certain amount of molten resin again into the cavity at high speed. And high pressure with a screw.
(4) After pressurizing, cooling and solidifying in the cavity. Open the mold and eject the product by ejector pin.

important point for custom plastic parts manufacturers

（1）カスタムプラスチック部品メーカー は、ホッパーから簡単に落下する可能性のあるペレットを選択する必要があります。
（2）ゲート部分は、メーカーがここからキャビティに注入する場所です。 そして残留応力が集中します。 ひび割れの恐れがありますのでご注意ください。
（3）射出成形品は収縮後の変化により変化するため、一定時間放置してから検査してください。
（4）ポリアミドなどの吸水性樹脂の場合、 カスタムプラスチック部品メーカー は、吸水による寸法変化に注意する必要があります。

injection molding of カスタムプラスチック部品メーカーの for the thermosetting resin

1. 概要概要

The resin is heated in the cylinder to give it fluidity. Which is injected into the cavity in the mold set to the curing temperature of the resin. where it causes a curing reaction and then is released from the mold. Things to consider when molding are:

• fluidity
• curability
• and supply.
• Since fluidity requiresin the cylinder, custom plastic parts manufacturers should set it to a temperature at which the resin does not harden.
• (2) Set the conditions so as to prevent hardening.
• (3) If the injection speed is too fast, heat will cure due to friction,

4 custom plastic parts manufacturers molding techniques

Low pressure molding

Molding shrinkage is small. And there is a tendency to increase the injection pressure in order to improve mold transferability. But on the other hand, when the injection pressure increases, the pressure gradient in the cavity increases. Causing “gas burn” and other problems. It may also cause defective molding.

In order to solve this, low pressure molding is a method of performing injection molding at low pressure. So that the pressure in the mold does not increase.

custom plastic parts manufacturers Injection compression molding

This is a method of popular custom plastic parts manufacturer that combines injection molding and compression molding.
After injecting the molten resin into the cavity where only the compression stroke is left, compression molding is performed. This method is suitable for:

• molding optical discs
• optical lenses, etc. and
• high-speed molding

Because molded products with less molding strain can be obtained.

High precision injection molding

This is the most economical way to produce plastic products in large quantities for カスタムプラスチック部品メーカー.

The manufacturing process is as follows: the plastic is heated to a liquid state. And fed under pressure to a metal mold, which forms the finished part.

custom plastic parts manufacturers Benefits

Profitability.

• The production of plastic products by injection molding on a thermoplastic machine is the most economical way of obtaining products from all possible.
• Once having made a mold, the cost of casting the part will be only a few dollars.
• Only the production of injection molded products allows custom plastic parts manufacturer to create a product of such complexity. And configuration that is unattainable by other production methods.

Highest precision and impeccable quality.

High-precision injection molding allows manufacturing products with tolerances of up to hundredths of a millimeter.

The shortest possible time. Unique performance.

Having a finished mold, カスタムプラスチック部品メーカー can cast a circulation of parts of 100,000 pieces in a couple of days.

Excellent performance.

The production of castings allows you to use any existing plastics to obtain the desired characteristics. And if necessary, カスタムプラスチック部品メーカー will be able to develop a special polymer mixture that are best suited for you.

What determines the cost of custom plastic parts manufacturers?

The cost of precision injection molding depends on two factors:

• the manufacturability of the mold and
• the volume of the batch of products.

The higher the automation of the equipment, the shorter the cycle of the form. And therefore, the cheaper the resulting product.

The production of plastic products is one of the key activities of the カスタムプラスチック部品メーカーの

China カスタムプラスチック部品メーカー industry dynamically developing and purchasing additional equipment. Expanding its capabilities in the production of plastic products by injection molding from plastic.

Plastic products are used in various sectors of the economy. Finished products made of polymers are:

• Inexpensive
• Lightweight
• well processed
• and can be recycled.

The manufacture of plastic products has its own technological features, depending on the purpose and size of the item.

According to the カスタムプラスチック部品メーカーの, the production of plastic products is carried out:

• 射出成形.The molten polymer fills the mold and is pressed. So get a large number of identical parts.
• 射出成形. Metal elements are installed in the formwork and polymer is poured. This is how solid products are made with inserts firmly fixed in plastic.
• Pressing method.Here, the metal elements are preheated and inserted into a mold filled with plastic.
