Guida passo passo alla produzione di stampi in plastica

Lo stampo in plastica è uno strumento per l' produttore di stampi in plastica materie plastiche e per le macchine per lo stampaggio della plastica. Questo metodo fornisce più dimensioni univoche a vari prodotti. Successivamente, viene fornito con un paio di tecniche di stampaggio che condivideremo di seguito ..

Cos'è lo stampaggio a iniezione? produttore di stampi in plastica

The plastic die mould manufacturer process is the most common suitable manufacturing method.

It is common for:

• Prototypes
• for bridge tooling and
• for small series production of parts for end users.

The process is based on a mechanism in which thermoplastic or thermosetting polymers are injected into a mold cavity. And then solidify as a finished part. Which is then ejected from the mold.

What are the advantages of die mould manufacturer?

A professional die mould manufacturer will offer rapid injection molding with short processing times. Which helps reduce development risks and limit overall manufacturing costs. Moreover, his automated processes begin with the data being sent directly to the factories.

 

So that he can often produce rapid prototypes. And parts for end users in just one day. In addition, die mould manufacturer high quality aluminum injection molds have a lifetime guarantee. And carry hundreds of thermoplastic resins and liquid silicone rubber materials.

What is Plastic injection molding? – produttore di stampi

With automated plastic injection molding process, individual prototypes and production parts for end use can be produced within 15 working days or faster. Generally, a die mould manufacturer uses aluminum molds. Which offers the advantages of low tool costs and accelerated production cycles. And keep more than 100 different thermoplastics in stock.

Le raccomandazioni di progettazione per lo stampaggio a iniezione di materie plastiche contengono informazioni sulle possibilità e sui limiti del processo.

Perché lo stampaggio a iniezione di materie plastiche è adatto al tuo progetto?

Un  produttore di stampi  lavora con stampaggio a iniezione rapida. Un processo reso possibile dalla tecnologia più recente che utilizza metodi di produzione automatizzati. Allo stesso modo, i modelli CAD vengono inviati direttamente alla produzione e inizia la produzione dello stampo.

Nella maggior parte dei casi, gli stampi sono realizzati in alluminio e non in acciaio. Tuttavia, questo è più veloce e meno costoso rispetto alla fresatura di stampi in acciaio.

 

A professional produttore di stampi thermoplastic injection molding process is a standard process with an aluminum mold without heating and cooling pipes. Which means that cycle times are slightly longer. This allows foundries to monitor:

• injection pressure
• cosmetic issues and the basic quality of the parts

So that they are ready to ship immediately upon completion.

Plastic granulate is loaded into a cylinder. Where it is finally melted, compressed and injected into the channel system of the mold. The hot plastic is shot through the sprues into the mold cavity. And the part is cast in this way.

Furthermore, ejector pins make it easier to remove the part from the mold. Which then falls into a loading container. When the series is complete, the parts will be packed and dispatched immediately. Here you can get our free design cube. Which illustrates the possibilities of injection molding?

How to choose best die mould manufacturer?

 

A leading die mould manufacturer can provide brass thread inserts if needed for injection molding production. This means that the additional effort for ordering, communicating with suppliers and organizing the timely delivery of the required parts is not necessary.

The risk of delays associated with third-party suppliers is eliminated. And if additional inlays are required due to rejects or quality errors. He will also take this into hand.

Ultimately, it is important to for a die mould manufacturer to offer you a simple and efficient insert service for your injection molding order. Similarly, he will provide parts from his extensive stock and you concentrate on your actual project.

Different types of moulding a plastic die manufacturer offers

Plastic products are supplies that can be found everywhere in daily life. Whether it is daily consumer goods or industrial supplies. However, there are many different production methods.

The following is an introduction to the most common produttore di stampi in plastica methods for plastic products. I hope it will help you choose the molding method suitable for your project.

Stampaggio a iniezione

About 80% of plastic products in daily life are injection molded. Injection molding is produced using an injection molding machine in conjunction with an aluminum mold or a steel mold.

The mold is composed of a core and a cavity. The injection molding machine heats the resin raw material until it melts. Using pressure to inject the molten plastic material into the cavity of the mold. And then the core and cavity are separated. In short product is ejected from the mold.

The advantages of injection molding are the large number:

• fast speed
• low cost, and
• good surface effect.

However, the structural complexity of the injection mold depends on the geometry of the product. The more complex the structure, the higher the cost of the mold.

In addition, the engineering produttore di stampi in plastica design of the mold must be refined to prevent defects. And it should optimize product quality and processing speed.

produttore di stampi in plastica Rotomolding

Rotational molding is suitable for producing large, hollow or curved products. Such as:

• kayaks or
• sinks for outdoor use.

Because the product is formed under the process of high-temperature rotation and the product is seamless. Moreover, it has higher strength. And the mold is relatively simple and the cost is lower.

The disadvantage is that the mold needs to be repaired after being used thousands of times, and the product quality is average, so it is not suitable for precision products.

Extrusion blow molding

Extrusion blow molding is commonly used to make thin-walled and inexpensive containers. Such as:

• disposable cups or

The production speed is extremely fast. And the mold making is simple. But it is not suitable for manufacturing complex or high-precision products.

The softened plastic forms a parison. Which is placed in two open-and-close molds. After the mold is closed, compressed air is blown into the parison to inflate. Until all adhere to the cavity wall.

After the mold wall is water-cooled, the plastic parts are quickly cured. And then produttore di stampi in plastica releases mold to obtain the finished product.

Injection blow molding- plastic die mould manufacturer

 

Injection blow molding is a process that uses air pressure to inject molten resin into the mold cavity. This process is easier to control and can be repeated. Moreover, it is usually used to produce transparent plastic beverage bottles. The surface effect is very good. But it is not suitable for producing wall thickness. Thicker products.

Reaction injection molding (referred to as RIM )

Reaction injection molding is often used in the automotive industry. Because the products produced by produttore di stampi in plastica method have the characteristics of light weight. But hard surface, so they can be made into:

• body parts
• dashboards or
• other parts by painting.

Questo metodo di stampaggio può lavorare solo materie prime plastiche termoindurenti. La materia prima plastica termoindurente subisce una reazione chimica nello stampo. Si diffonde come una schiuma. E riempie l'intera cavità dello stampo. Al termine della reazione chimica, la plastica si solidifica per diventare un prodotto finito.

produttore di stampi in plastica Tecnica di stampaggio a compressione

produttore di stampi in plastica  utilizza la tecnica di stampaggio a compressione per posizionare il materiale nella cavità dello stampo per pressofusione dopo il preriscaldamento. E curare la plastica mediante pressione e calore dopo che lo stampo è chiuso. Questo metodo di stampaggio è adatto per produrre:

• chiavi di plastica
• guarnizioni
• O-ring, o
• altri prodotti morbidi, facili da modellare e con pareti sottili.

This molding method is relatively cheap and wastes less material. But the stability of the product is more difficult to control. And more attention must be paid during the mold design stage.
