PROSES DAN PERANGKAT DESAIN INJEKSI INJEKSI PLASTIK

Plastik adalah bahan yang sangat serbaguna dan menemukan kegunaannya di semua bidang kehidupan kita. Banyak dari kita bahkan tidak sepenuhnya menghargai betapa kita mendapat manfaat dari penemuan ini saat ini, but there are people among us with a very real appreciation for plastic’s benefits and flexible applications. If you’ve ever done a DYI project that required some specifically molded parts, Misalnya, you’ve likely come to appreciate the usefulness of plastic quite a lot.

What is plastic injection moulding

Plastic injection moulding is the method of manufacturing parts made of thermoplastic and thermosetting plastic by melting and forcing into moulds where they cool to form the desired object.

How does plastic injection moulding work?

The process of plastic injection moulding usually begins with an industrial designer or engineer who designs a product. This is followed up by the work of a toolmaker or mould maker who makes the mould to fit the design created. These moulds are metallic and usually made using either steel or aluminum. Using machines, they are made to acquire the exact shape desired by the design. Once this is done, the process of actually making the plastic follows. This involves thermoplastic and thermosetting plastic being fed into a heated barrel and mixed. This melted material is then forced into the cavity of a mould and there it cools and hardens to form the desired part.

Some characteristics of the process:

  1. It uses melted and mixed thermoplastic or thermoset plastic as the base
  2. It uses a plunger which acts like a screw or a ram to force the melted material in the mould
  3. It makes a shape that is open-ended and has taken the shape of the cavity of the mould
  4. It shows a parting line and gate marks on the finished products and the ejector pin marks can also usually be made out

Plastic injection moulding design process and tooling

The process used to convert raw materials into usable plastics is called injection moulding. This process is used to manufacture products/parts from both thermoplastic and thermosetting plastic materials. These materials are melted, designed and cooled in order to be released for use. Injection moulding is commonly and widely used to manufacture a variety of parts, usually for the car industry.

Mulanya, the moulding machines used the pressure technology to give the needed end products. This graduated to pneumatic cylinders and then the hydraulic systems which also borrowed from the die cast technology. The modern machines use the injection barrel of a plunging helical screw because it is fast and efficient.

The injection process comprises four easy steps which are:

1.Cetakan injeksi juga digunakan untuk memproduksi beberapa barang sehari-hari seperti sikat gigi atau mainan plastik kecil — Di panggung ini, the mould is held securely by the hydraulically powered clamping unit which in turn pushes the mould and exerts force to keep it securely closed while being injected.

2.Injeksi — The polymeric material which is available in powder form is transferred into the injection moulding machine by the injection unit for melting. Once it is molten, it is quickly injected into pressure packs under a certain temperature.

3.waktu injeksi dapat diperkirakan dengan volume tembakan — The molten material solidifies quickly after a pre-determined cooling time. waktu injeksi dapat diperkirakan dengan volume tembakan, it adopts the shape of the desired part. The cooling process is sometimes affected by shrinkage and this is corrected at the injection stage where additional material is allowed to flow into the mould.

4.waktu injeksi dapat diperkirakan dengan volume tembakan — This uses a particular mechanism to push the part out of the mould. Some force must be exerted since the part adheres to mould. A release agent may be sprayed on the surfaces of the mould to facilitate ejection.

The moulding design and tooling puts into consideration the part design. This includes the draft, ketebalan dinding, radii and corners, ribs and bosses and the weld part lines. The draft describes the degree of a taper needed to allow the ejection of the moulded plastic. The ribs are necessary to add the structure strength of the part design. The bosses locate, mount and assemble the moulded parts. The radii help to avoid sharp corners and also help to strengthen the part.

A good plastic moulding company can be absolutely indispensable for various purposes, so if there’s even a remote possibility that you may need services of this type anytime soon, it’s in your best interest to research your local market for plastic services and find out which companies can work best for you. Remember that the quality of a custom plastic molding job can vary significantly from one company to another, and it’s important to invest in something that will work out exactly like you require.
