Low / High Cavitation
rongga tunggal direka untuk menghasilkan satu bahagian setiap kitaran. Mereka adalah pendekatan yang menjimatkan apabila jumlah bahagian rendah kerana ia lebih murah untuk dibina. Mereka juga mempunyai masa pendahuluan yang lebih pendek. Kelemahannya adalah kos bahagian yang lebih tinggi dalam pengeluaran cetakan.

Acuan berbilang rongga menghasilkan lebih banyak bahagian setiap kitaran. Kelebihan utama adalah peningkatan kapasiti dan kos bahagian yang lebih rendah kerana lebih banyak bahagian dapat dihasilkan dalam masa kitaran yang setanding.

Family Mold
A family mold has a single mold base but two or more different cavities, allowing for the production of two or more different parts. All the parts can either be produced simultaneously or shut-offs can be used to isolate production to selected cavities. For best results in molding, the parts should be similar in size, shape, resin, and anticipated volumes, especially if the intention is to run all parts at the same time. Automation may be necessary to separate the pieces during or after production.

If mold cost is a driving factor and volumes are low, a family mold can provide cost savings and versatility.

Unscrewing Molds
Unscrewing molds are the most common method of creating threaded holes within a plastic part. These molds are automated with small drive systems (rack & pinion, electric, or hydraulic motors) that are tied into the process and rotate threaded features to extract undercut features. Threads can be internal or external, and the extraction is tied into the press cycle.

Multi-shot / multi-component tooling allows a product designer to use two or more dissimilar materials on the same part within the same cycle. There may be a variety of reasons why differing materials would be desired, including different physical properties or simply appearance. These molds often utilize multiple manifolds within one tool. Multi-shot tooling can be an elegant solution for complicated products, and can be used for color changes within a product line.

Specialized presses and molds are necessary to run multi-shot tooling. Multiple machine nozzles, hot runner systems and mold rotation may become necessary. While Matrix currently does not have any multi-shot molding presses on our floor, we are particularly adept at designing and building these complicated tools and have been doing so for decades.

Hot Runner Molds
Alat pelari panas menggunakan manifold terkawal suhu untuk mengurangkan atau menghilangkan sekerap pelari dari kitaran. Titik suntikan boleh berada di luar bahagian atau terus ke bahagian tersebut. Ini dapat meningkatkan masa kitaran, kerana sistem sprue atau pelari sering menjadi faktor penentu pada kitar acuan. Dan, menghilangkan pelari menjimatkan bahan terbuang yang mahal.

Acuan pelari panas memerlukan pengawal suhu untuk penekan yang mereka jalankan, dengan pengawal bersaiz sesuai dengan manifold dalam acuan. Sebilangan kos penyelenggaraan acuan lebih tinggi pada alat pelari panas, tetapi mereka sering membayar sendiri dalam jangka masa panjang melalui penjimatan bahan dan kitaran. Hal ini berlaku terutamanya bagi aplikasi yang memerlukan resin gred kejuruteraan yang mahal atau jumlah tahunan yang tinggi.

Cold Runner Molds
Cold runner molds are good examples of more traditional tooling in that they utilize sprues and runners to gate into the part. This is typically the least complicated form, however may result in larger amounts of wasted material and slower running cycles. Depending on the application, a percentage of wasted material may be re-ground and re-processed for future use, though this could affect the physical properties of the resin.

Dealing with more advanced, high-cost materials such as engineering and medical grade resins or the inability to use regrind in your application may lend itself to using a more efficient hot runner mold for your project.

Insulated Runner Molds
Insulated runner tools resemble more traditional cold runner molds but utilize cartridge heaters or other methods of heating to form a surrounding layer of molten resin, forming an insulated “”cull”” to create a similar effect to a hot runner system. This approach is less expensive than using a hot runner which requires a temperature controller and also has the benefit of allowing for faster color and material changes. However insulated runners are not suitable for all types of materials and typically do not work well with more demanding engineering grade resins.

Two / Three Plate
Three-plate molds are cold runner tools, but by adding a third plate to the runner system, you are able to locate your injection point into virtually any location on the tool. This is usually less expensive than adding a hot runner system, however this type of mold often has large and unwieldy runners, which can be more difficult to automate.
