مصنع قوالب الحقن: Roto Molding Vs Injection Molding

إذا كنت تخطط لإنشاء منتج بلاستيكي ، فأنت بحاجة إلى العثور على أفضل مصنع لقوالب الحقن في المدينة. ومع ذلك ، قبل أن تمضي في هذا الطريق ، من الضروري أن تكون لديك معرفة ببعض المفاهيم الأساسية لقولبة البلاستيك.

Regardless of the product type that you are planning to purchase, may it be playground equipment or a plastic kayak, you are making an investment. You would narrow down your options while keeping the ROI factor in mind. Therefore, we highly recommend that you weigh the benefits of rotational molding as well as plastic injection molding before you finalize the manufacturing process.

Once, you understand the difference, you will be in a better state to make a knowledgeable decision. So, here we go!

Comparison between Injection Molding and Roto-Molding

What is Roto Moulding?

Roto molding or more formally known as the rotational molding is a production technique that manufacturers use to create hollow parts of limitless sizes. The technique involves multiple layers, thus making it possible to manufacture large parts at affordable prices.

Using the rotational molding process for manufacturing poly-based products yield effective results. Manufacturer pours plastics or resins usually in the form of power into a hallow mold. After that the mold is bolted tightly to ensure that no product dispenses once, their rotation starts.

After securing the mold, place it into an oven. Then rotate the mold at an even speed. The rotations take place both in vertical as well as horizontal planes. The constant rotation along with the heat melts the resin and distributes if evenly inside the mold. This would ensure even distribution of the melted powder inside the mold.

Result

The outcome of the process is a pre-designed part. The part would have a uniform wall thickness, thus ensuring its quality and robustness. Also, do bear in mind that the corners for the parts created using the rotational molding technique are denser.

The reason being, the material tends to accumulate at the edges and corners of the mold. In case, you want to avoid this, you would have to opt for another molding technique. We will talk about that also later in this article.

For now, let’s focus on the advantages the rotational molding technique has to offer.

Rotational Moulding Technique Advantages

Below are the top advantages of using roto-molding.

Design Flexibility

Rotational molding offers design flexibility. Thus, allowing the manufacturing of highly complex parts. So, if the part of the component is geometrically complex, use rotational molding for superior parts and better manufacturing quality.

Strong and Steady Parts

The moulding procedure yields better results. It ensures even spread of the plastic power across the inner walls of the mold. Thus, resulting in a flexible, stronger, and robust end product. It is highly effective for products that will be exposed to a rugged environment.

These parts can stand high temperatures as well as the low ones without cracking or breaking. The reason being, the rotational moulding technique eliminates the stress points as it has more thickness at the edges and corners of the parts.

Consistent Wall Thickness

With rotational molding, it is possible to achieve consistent wall thickness. This further enhances the overall strength and robustness of the product.

Inexpensive Tooling

Since the tooling required for the rotomolding is inexpensive, thus it is preferred by manufacturers around the globe. The inexpensive tool would lead to lower-priced components and parts. Thus, luring more and more consumers.

Limited Production Time

In addition to manufacturing high-quality products, the process also ensures limited production time. It means, it can do mass production in a limited time. Something, everyone wants. After all, there is a race out there and the one wins, take it all.

Improved Throughput

With rotomolding, it is possible to effortlessly remove the throughput. After all, the technique does decrease the labor hours in an effective manner.

Enhanced Surface Finish

Parts created using the rotational moulding lack the welding lines or the parting lines. Their surface is clear of all imperfection. In most cases, there is no need for additional work on the product, after it comes out of the mold.

What is Injection Moulding?

و injection moulding die manufacturer injects a melted plastic mixture using high pressure into a mold’s cavity. Before injection, the plastic is hot. It tends to cool down within the wall of the mould, thus taking up its shape.

It is possible to design the mould into any size or shape. In order words, you can design the mold according to the requirement of the end product.

NOTE: Designing a mold requires skills and expertise. Imperfection in the mold would result in errors in the final part or component.

Manufacturers use either steel or aluminum to create the mold. They use a mold to create identical copies of a single part. Thus, it is extremely useful in mass production. You can also use mould to create multiple parts that would come together to create something bigger and more complex.

An Injection moulding die manufacturer would recommend injection molding when you want to create multiple copies of the same component or the part. It is an effective plastic manufacturing process.

Advantages that Injection Moulding Die Manufacturer Offers

Complex Mold Design

With injection molding, it is possible to create extremely complex designs. Creating molds is a challenging task. However, it offers the facility of creating your desired shape. It means the mold takes up any shape that you like.

بمجرد أن يصبح القالب جاهزًا ، يمكنك إنشاء العديد من الأجزاء والمكونات كما تريد ، بغض النظر عن مستوى تعقيدها. تشتهر تقنية القولبة بالحقن في صنع أدوات المطبخ والمقابض وأغطية الزجاجات من بين أشياء أخرى.

التنوع المادي

على عكس تقنية القولبة الدورانية ، حيث يمكن للمصنعين الوصول إلى عدد محدود من المواد. يوفر قولبة الحقن تنوعًا من حيث المواد. يمكنك استخدام عدة مواد لإنشاء أجزاء ومكونات.

فعاله من حيث التكلفه

تعتبر تقنية القولبة بالحقن أكثر فعالية من حيث التكلفة مقارنة بالقولبة الدورانية. لا تستخدم المواد المضافة التي تزيد من سعر الصب الدوراني. ومع ذلك ، فإن المواد المضافة تقدم بعض الفوائد.

So, to incorporate those benefits into injection molding, the injection moulding die manufacturer, uses additives for this type of molding as well. In addition, injection molding is extremely affordable, especially for bulk manufacturing.

It is preferred for mass volume as it can produce more items on the production line. Thus, decreasing the overall manufacturing time of the components and parts.

Injection Moulding Die Manufacturer Vs Rotational Molding: Which Process Wins?

Both plastic and injection moulding technique has its own benefits and demerits. So, it greatly depends on your product requirement. If you are planning to produce a limited number of parts or components, you have the time and you do not want to compromise on quality, go with rotational molding.

من ناحية أخرى ، إذا كان هدفك هو الإنتاج الضخم. تريد أن تكون الأجزاء جاهزة في وقت محدود وتحتاج إلى أن تكون التكلفة الإجمالية منخفضة ، فإن قولبة الحقن ستفي بالغرض. على الرغم من ذلك ، ضع في اعتبارك أنه مع صب الحقن ، تتدهور الجودة.

بالطبع ، يمكنك تعزيز الجودة من خلال تضمين المواد المضافة. سيسمح لك ذلك بتحسين الجودة الشاملة وإنهاء المنتجات والأجزاء.

فيما يلي بعض الفوائد.
