가장 많이 사용되는 2 가지 성형 방법의 장단점

3D 프린팅과 비교 한 플라스틱 사출 성형

The 플라스틱 사출 성형 and 3D printing are two different production methods for the manufacture of parts for industry. Both of these methods allow professionals to obtain parts simply from three-dimensional designs. In this article, we will compare the two production modes to determine which types of applications correspond to them.

두 가지 생산 방법은 어떻게 작동합니까?

각 생산 모드의 이익, 장단점을 더 잘 이해하려면 작동 방식을 아는 것이 중요합니다. 그리고 이러한 모드를 생산 단위 내에 통합하는 방법.

3D 프린팅에 필요한 재료

3D 프린팅으로 제조하려면 3D 프린터와 소모품이 필요합니다. 플라스틱 사출 성형. 첫째, 플라스틱 필라멘트의 스풀을 사용하는 FDM (Fused Deposition Modeling)입니다.

둘째, 액체 수지 카트리지를 사용하는 SLA (Stereolithography)입니다. 두 경우 모두 인쇄를 통해 재료의 연속 레이어를 인쇄하여 부품을 얻을 수 있습니다. 인쇄가 다소 간단하고 특성이 다른 재료가 많이 있습니다.

플라스틱 사출 성형 : 어떻게 작동합니까?

As the name suggests, 플라스틱 사출 성형involves injecting molten material into a mold. Then, to let cool and harden the material in order to obtain the final piece. The injection molding method requires more elements than 3D printing.

An injection molding machine, also known as an injection press, will be required. This consists of a worm to convey the material in solid form. There is also a heating unit to melt the material.

Finally, the system has a high-pressure injector for filling the mold. The injection molding also requires a mold made previously. Most often it is made of aluminum, hardened steel or copper. Obviously, material is needed for the design of the final part.

The advantages of 플라스틱 사출 성형 / 3d printing production methods

따라서이 두 기술은 최종 부품을 설계하는 데 사용되는 기술과 사용에 필요한 재료면에서 다릅니다. 3D 프린팅과 플라스틱 사출 성형 도 관심이 다릅니다.

3D 프린팅의 이점

3D 프린팅 기술의 경우 재료 측면에서 투자 비용이 상대적으로 낮다는 것을 알 수 있습니다. 실제로 시장에는 가격이 매우 다양하고 예산에 관계없이 접근 할 수있는 많은 기계가 있습니다.

또한 레이어 별 적층 제조 기술을 사용하면 제조 과정에서 모델에 설계 오류가 있는지 쉽게 감지 할 수 있습니다. 3D 모델을 재 작업하여 신속하게 수정할 수도 있습니다.

Finally, 3D machines make it possible to design parts with very fine details very simply using support filament. Precision is one of the strengths of 3D printing.

Benefits of 플라스틱 사출 성형injection molding

The main advantage of the injection molding method lies in the ability to mass produce parts quickly and with high precision in design repeatability.

Then, the objects produced using injection molding have high strengths. In the sense that they are designed in one layer and in one go with the injection of all of the liquid material inside. of the mold.

Finally, the injection of material inside the mold makes it possible to guarantee exact compliance with the quantity of material necessary for the manufacture of the part. If the mold is well designed, there is no loss of material during the manufacturing process.

Disadvantages and limitations

Like all production methods used in industry, 플라스틱 사출 성형 and 3D printing also have certain limitations. It can be more or less mitigated or avoided depending on the method chosen.

The limits of 3D printing

3D printing is somewhat limited in terms of the build volume of the parts. Indeed, most of the machines available on the market have relatively small printing volumes. And they can be a brake for certain applications. There are however large volume machines (up to one cubic meter) but the initial investment will be higher.

3D printing has another limitation, linked in part to the printing volume of the machines. It is the capacity to produce parts in large series. It will still be possible to produce in small and medium series by opting for production 3D printers.

The weak points of Plastic injection molding

Regarding 플라스틱 사출 성형, the main problem lies in the difficulty of obtaining complex geometries. Indeed, the creation of a mold requires to design an inversion of the final part. It limits and significantly complicates the possibilities in terms of design.

Correcting errors is also more complex. When a manufacturing error is found on injection molding, it will be necessary to completely recreate a new mold. This will be penalizing in terms of time and in terms of cost.

The cost which is also one of the limits of the injection. Indeed, the initial investment for this kind of production will be much higher than 3D printing. In addition, the design of new molds also represents a high cost to be taken into account when calculating the return on investment.

Conclusion

If the purpose of 3D printing and 플라스틱 사출 성형 is the same, namely the production of parts, it turns out that these two manufacturing methods each have their interests in particular applications.

Indeed, injection molding will be more interesting for the production of finished parts in large series. while 3D printing will on the contrary make it possible to produce parts with a complex design in small series.

The investment, lower for 3D printing, will also be a factor to be taken into account in decision making. Which method do you prefer and for which type of application? Feel free to share your experiences by leaving a comment below the article.
