기본 플라스틱 성형 방법을 배우기위한 초보자 안내서

플라스틱 성형이란? 플라스틱 성형 부품 제조업체

플라스틱 성형 부품 제조업체 는 모든 복잡성과 디자인의 강력한 제품을 얻기 위해 실리콘에 플라스틱 성형을 사용합니다. 얻은 요소의 두께와 부피도 다를 수 있습니다.

Furthermore, special molds are used for work. Which allow reproducing several hundreds or thousands of identical elements. The methodology is used by enterprises and individuals for small-scale and large-scale production.

The so-called color-changing substance produced by Plastic molded parts manufacturer

Molding is the process of making various forms of polymers like:

• Powders
• Pellets
• solutions or dispersions

into products of the desired shape. It is the most important in the entire process of plastic material molding and processing. It is the production of all polymer materials or profiles the necessary process. Plastic molding methods include the following:

• extrusion molding
• injection molding
• compression molding
• transfer molding
• lamination molding
• blow molding
• calendar molding
• foam molding, thermoforming, etc.

Various molding methods have their adaptability which are introduced by Plastic molded parts manufacturer

What happens when the molded product changes color?

The so-called color-changing means, that the chemical properties of some substances contained in the molded product may change.

The reason for the color-changing needs to be considered according to various constituent substances. Plastics are composed of several of the following 5 substances:

(1) polymers (resins)

(2) stabilizers

(3) performance-imparting substances

(4) filler

(5) other resins.

Plastic molded parts manufacturer Discoloration of polymers

Many products made by Plastic molded parts manufacturer hardly have the problem of discoloration of ” polymer.  In organic substances, because the structure of the color is limited, it can be judged whether it is prone to a certain degree of discoloration according to the structure of the polymer.

For example, it is known, the basic skeleton of resins. Such as urethane series is easy to form covalent double bonds. So it is susceptible to discoloration due to ultraviolet rays and other factors.

Plastic molded parts manufacturers stabilized properties

The stabilizer added to the color-changing resin material has some properties. It absorbs the light energy of ultraviolet rays and other substances or captures free radicals.

Since ultraviolet energy and free radicals will decompose the polymer, their stabilizers are used instead of polymerization React to prevent the deterioration of the polymer. However, the more effective the stabilizer the more likely it is to change color after the reaction.

Especially the quinone type and other stabilizers formed by 플라스틱 성형 부품 제조업체with an aromatic or fluorine ring structure. Although, there are the most varieties and the best performance on the market but the discoloration is also the most obvious.

Plastic molded parts manufacturer Performance-imparting substances

The performance-imparting substances differ in their properties and methods of use. So,  Plastic molded parts manufacturers should judge individually and cannot be generalized.

What is the function of the Filler?

Many fillers can be said to have almost no problem with discoloration. Such as:

• engineering plastic glass fiber and
• Mineral fillers.

However, in glass fiber and other materials sold as products, a small amount is added due to that addition. So these resins have the possibility of discoloration due to thermal degradation, although this possibility is very small.

(5) Other resins

The discoloration problems of other resins are basically the same as:

1. In summary, the substance most likely to cause discoloration is a stabilizer. However Plasticmolded parts manufacturer uses it in order to prevent the deterioration of the polymer.
2. At present, stabilizer manufacturers are still developing stabilizers with higher effects and less discoloration. At the same time, many resin and plastic molded parts manufacturers are also studying ways to better use stabilizers.

Factors involved in Plastic molded parts manufacturers resins

The factors that cause discoloration of materials can be summarized as follows:

• Caused by thermal energy.

If the resin is thermally decomposed in a high-temperature environment, free radicals are sometimes generated. Furthermore, in general, if the resin stays in the molding machine barrel for a long time. Then tar-like substances will be generated. Causing the color changes to brown or black.

The daylight caused by light energy do not need to repeat. Even fluorescent lamps emit ultraviolet rays. If placed in this environment for a long time, the resin will change color due to the action of ultraviolet rays.

Because the nature of the stabilizer reacts, the color ranges from yellow to Between brown. The amount of energy absorbed varies depending on the color of the molded product created by plastic molded parts manufacturer. The speed of discoloration also varies depending on the color of the molded product.

Plastic molded parts manufacturers mechanical  energy

Sometimes the mechanical energy becomes heat energy, causing resin discoloration. Specifically, when the molding machine wants to forcefully transfer the resin without sufficiently heating the resin in the metering area

플라스틱 성형 부품 제조업체의 변색 대책 방법은 무엇입니까?

1. 성형으로 인한 변색

The biggest factor of 플라스틱 성형 부품 제조업체실린더에 수지가 남아 있다는 것입니다. 이를 위해 단축 조치를 취할 수 있습니다. 수지의 체류 시간은 장기간 보관 후 수지를 완전히 교체하는 조치를 취합니다.

온도가 높을수록 유지율이 높아지고 색상이 변합니다. 따라서 핵심은 배럴 온도를 과도하게 높이 지 않는 것입니다. 더욱이

2. 빛으로 인한 색 변화

빛에 의한 색상 변화는 실내에서 사용되며 매우 느립니다. 일 용품 등의 경우 플라스틱 성형 부품 제조업체  는 무시할 수 있습니다. 이때 형광등에 특별한주의를 기울이는 것이 도움이됩니다.

예를 들어 창고 및 기타 장소에 제품을 보관할 때. 직접 조사를 피하기 위해 빛을 차단하는 것이 가장 좋습니다. 그리고 언제든지 형광등을 끄십시오. 직사광선이 비치는 실외 및 자동차에서 사용하는 경우.

 It is recommended to choose weather-resistant products by 플라스틱 성형 부품 제조업체.

전자는 일반적으로 원자 내에 쌍으로 존재합니다. 그러나 매우 드물게 이러한 쌍을 이루는 전자는 열과 빛의 작용에 의해 파괴됩니다. 그리고 별도의 형태로 존재합니다.

The atom or atomic group containing this electron is called Free radicals. Free radicals have high activity and are extremely unstable. Once produced, they will quickly decompose the substance or react with other substances.

When the free radicals react with the resin, they often decompose their main chain, which reduces their mechanical properties.

The material forming method of plastic molded parts manufacturer

It is an important part of the part design. It is also a problem that 플라스틱 성형 부품 제조업체 are extremely concerned about. And it is also a key factor in the material processing process.

In addition to injection molding, plastic molding also has extrusion molding. Such as:

• sheets and pipes
• Blow molding, such as mineral water bottles.

But no matter what molding method, there should be a “limited” way of existence. This thing you can Understanding as a mold. Compared with other molding methods, injection molding is undoubtedly the most common processing method among molding methods

What are the molding methods of plastic molding machines? Plastic molded parts manufacturer

Plastic molding machine processing is engineering technology. which involves various processes for converting plastics into plastic products. During the plastic molded parts manufacturer transformation process, one or more of the following conditions often occur. Such as the rheology of the polymer and changes in physical and chemical properties.

The main equipment for compression molding and compression molding is a press and a mold. Presses are self-contain hydraulic presses, with tonnages ranging from tens of tens to hundreds of tons.
