A glimpse of Vacuum casting and application

Vacuum casting is the most opted copying technique sourced to manufacture small series of well-designed plastic parts. It is the familiar option for fast production of high quality prototypes or end use products. Two major component used in the manufacturing method is polyurethanes and silicon molds. Compared to the injection molded components, vacuum casting is feasible to create high quality parts. It is ideal to source this option when you are manufacturing for fit and function testing, marketing purpose and also for low volume plastic production. If you are wondering about vacuum casting method, then explore this article to enlighten you way.

Vacuum casting:

It is a versatile technology which possess the potential of producing parts in various ranges such as polyurethane resins, cast nylon, fabricate and replicate etc. A single mold can produce up to 50 parts but it needs re-tooling if it is employed further.

This method is ideal to use where functional plastic prototype parts with fine details are needed. Patterns, dimensions, textures and profiles can be replicated in this process. Some of the widely manufactured products from this method are listed as follows.

Functional testing such as thermal and air flow testing

Assembly line trails

Presentation purposes

Vacuum casting is quite slower process compared to SLA since it involves additional process which are sometimes manually exhaustive. The time consumed in the manufacturing process is mainly depends on desired characteristics such as size and other added details. Size is the key factor that prolongs curing time of the material.

A single master mold is created from which is sourced to manufacture required products. The Master mold should possess exact dimensions and has no flaws. It is generally made from silicone rubber. Resin is poured into the vacuum chamber for the casting purpose.

Application of vacuum casting:

Vacuum casting has many application and the prominent one are listed below.

Pre-launch product testing

Manufacture a small series of housing and covers

Concept models and prototypes


Parts manufactured from vacuum casting possess various properties and they are listed as follows.

Resistance to heat

Desired color can be added to the parts

Fire resistance to some extent

UV stability

The process can deliver parts with varying degrees of flexibility or rigidity. When combining prototyping technologies with vacuum casting, it can match the needs of expensive purpose made production tooling. As it is familiar for producing high quality products, numerous manufactures are roping in.

When the products you manufacture demands fine detail and accuracy, nothing satisfies you like vacuum casting method does. It requires no need of expensive hard tooling. Numerous firm are rendering service on manufacturing parts employing vacuum casting method. Hiring them for your needs is also a worth considering option. Outsourcing the manufacturing process encompasses many benefits. The firm you have bonded with, possess experienced professional on their hand and they take care of all the process to achieve high caliber output.

Source this process better and ambush your caliber to golden standard.
