Pengilang Bahagian Plastik Tersuai: Bagaimana Ia Dilakukan?

Terlepas dari alasan anda untuk menghubungi pengeluar alat ganti plastik tersuai, penting juga untuk memahami asas bagaimana proses pembuatan dijalankan. Di samping itu, anda perlu mengetahui mengenai teknik pembinaan model moden dan canggih.

In this blog post, we will be covering the basics of the manufacturing of custom plastic parts, in addition to the common modeling and plastic molding machines and concepts. So, let us begin.

Custom Plastic Parts Manufacturers – Manufacturing Process

Plastics or more formerly known as the polymers are widely used around the globe. They are available in a wide variety as well. Different elements such as nitrogen, oxygen, chlorine, and hydrogen are used in their composition.

In addition, these plastic parts have high molecular weights. The objective of manufacturing plastic is to imitate the components of natural materials. For instance, it is often used to replace wood products.

These materials generally are a result of natural product conversion. However, sometimes you can create them by combining essential chemicals such as coal, oil, or natural gas.

Below is the general idea of how to manufacture the custom plastic parts.

Propose a Design

It is but natural, that for a custom plastic part, you would have to provide a design. After all the component or the part needs to be according to your specification.

So, start with sketching your design on a piece of paper. Just make sure that the end of your sketch has all the required details. It would be better if you draw a 3D model for it.

In case, you lack the skills, we suggest you go on and hire a professional. Provide them with all the details, and they will design your product or parts accurately. After all, this is an important stage, where you would make the product achievable.

So, to reduce the designing time, you can present the design to you to achieve goals. You can reach out to tech experts to ensure that your designs have no technical errors.

Choosing Plastic Moulding Design

In the manufacturing industry, you will find a number of molding methods. In case, you are looking for more details, you should read our different types of Moulding Process or the comparison between extrusion and Thermoforming.

Thus, there is no denying that custom injection molding is among the most popular techniques. So, with plastic injection moulding, you can manufacturer parts in high quantity and at lower rates.

However, do bear in mind that the process you choose would depend upon a number of variables. For instance, the number of parts you need, the initial design, and the product’s overall use.

Below are some additional plastic moulding techniques and their variants.

3D Printing

Using a CDA model, 3D printing allows direct creation of 3D parts. Thus, the technique uses layer by layer concept for manufacturing the part of the component. Instead of molding the entire material at once, it goes layer by layer.

Manufacturing Process

Step-up

There are different print preparation software that you can use for laying out the model and its orientation. Both these factors are according to the building volume of the printer, its slicing capabilities, and additional support structures.

Also, the software would heed to every aspect of the printer, to ensure that your product can be produced in the best possible way.

Printing

There are different 3D printing technologies available, thus the printing process would vary as per the technology that you use. For example, FDM – Fused Deposition Modeling—melts the plastic filament to produce a product.

Likewise, the Selective Laser Sintering uses fuses powdered plastic and the Stereolithography incorporates the liquid resin for product creation.

Post- Processing

After completing the printing process, remove the products from the printer. Manufacturers would have to clean or wash them. In addition, they might perform some post-cured methods. However, this mainly depends on the technology you use.

Kos dan Pengeluaran

With 3D printing, you do not require additional tools and the step-up time is also minimal, manufacturers prefer it over the old techniques. You can ignore the cost of producing a custom part especially in comparison to the conventional manufacturing processes that take ages.

Thanks to technological advancement, even the low-level consumers also have access to affordable 3D printing techniques. It is possible to develop low to mid-volume applications at reasonable prices.

See the table below for additional information on 3D Printing.

Materials

Since there are a number of 3D printing technologies and 3D printers available in the market, thus you have a wide variety of material. So, the choice of material again depends upon the type of technology you use.

See the table below for different material types and the technologies that use them.

 CNC Machining

Lathes, Mills and similar subtractive processes controlled by the computer are part of the CNC machining. The technique applies different methods such as drilling, cutting, boring, and grinding onto a solid block, plastic, metal rods, or bars.

CNC machining is slightly different from other plastic parts. Furthermore, the technique involves using a subtractive process in which milling – fixed part- or a spinning tool is required to remove the material.

It is possible to use a spinning part with a lathe (Fixed Tool) as well.

Manufacturing Process

Job Setup

For CNC machining, an intermediary step from CAD to CAM is required. So, the parts of the tool would be responsible for the movement of the cutting tools, the speed at which they would move and the changeovers required.

Pemesinan

Furthermore, for the subtractive process to start, it is important to shift the toolpaths to the machine. So, you might have to set the workpiece in a new position as the tool heads would need additional space to work on the new areas.

Post-Processing

Selepas pembuatan, penting untuk membersihkan bahagiannya. Mereka juga dipangkas dan dikurangkan.

Kos dan Pengeluaran

Pemesinan adalah pilihan yang baik untuk aplikasi bahagian plastik yang memerlukan toleransi yang ketat. Di samping itu, ia berfungsi dengan baik untuk bahagian dan komponen yang mempunyai geometri kompleks.

Contoh Pengilang Bahagian Plastik Biasa

Pengguna dan pengeluar sangat bergantung pada pemesinan untuk tujuan pembuatan prototaip. Ia menunjukkan hasil yang berkesan dan cekap. Di samping itu, ia berkesan untuk bahagian penggunaan akhir seperti bushing, gear, atau pulley.

Prosesnya dilakukan dengan kos persediaan rendah hingga sederhana. Walaupun begitu, ia dapat menghasilkan bahagian berkualiti tinggi dalam waktu yang sangat singkat. Ia juga berfungsi dengan sebilangan bahan.

 Bahan

 Adalah mungkin untuk membentuk plastik yang paling sukar dengan tahap kesukaran mesin yang berbeza. Dalam kes plastik termoset yang lebih lembut, pengeluar memerlukan alat tambahan untuk tujuan sokongan bahagian semasa proses pemesinan.

Berikut adalah beberapa Contoh Plastik yang biasa

• Polistirena (PS)
• Akrilik (PMMA)
• Nilon poliamida (PA)
• Acrylonitrile butadiene styrene (ABS)
• Asid polilaktik (PLA)
• Keton polieter eter (PEEK)
• Polikarbonat (PC)
• Polietilena (PE)
• Polivinil klorida (PVC)
• Polipropilena (PP)
• Polikarbonat (PC)
• Polioksimetilena (POM)

Bina Prototaip

Now that you have the basic concept of different molding and machining techniques for plastic molding, you need to start with a prototype. A prototype would help you understand the viability of your idea.

With prototype can you eliminate almost all errors before going into the production phase. In addition, there are several prototype tools available, ask your custom plastic parts manufacturers for the best one in the market.

 Find Custom Plastic Parts Manufacturers

Once you have finalized the design, it is time for prototyping and production. If you have in house facility, you can produce your own parts. If, not, you can reach out to one of the leading custom plastic parts manufacturers such as the Kaito Mould.
