By leveraging CNC milling services, you can benefit from precise and repeatable manufacturing processes, reduced production time, and the ability to create custom parts tailored to your specific needs.

What Is Vacuum Casting?

Polyurethane vacuum casting is a specialized technique for making high-fidelity copies of master patterns using inexpensive silicone molds and pourable casting resins. Copies made in this way demonstrate the same quality as plastic injection molded parts while taking only a fraction of the time and expense to produce.

Advantages Of Vacuum Casting

Molds are affordable and can be created quickly, within a few days. A wide variety of polyurethane resins are available for casting, including options for overmolding. The resulting cast copies boast high accuracy and an excellent surface finish. Additionally, molds are durable enough to produce 20 or more replicas. This makes them ideal for engineering models, samples, rapid prototypes, and as a bridge to production.

Materials for Vacuum Casting
You can choose a wide range of vacuum casting materials depending on the peculiarities of your project. Here are some choices for you:
Image	Materials	Description
	ABS	ABS is a thermoplastic polymer, is widely used due to its exceptional resistance to impact, temperature, and chemicals. It also offers a sleek surface finish and is easy to produce and handle.
	POM	POM, also known as acetal or Delrin, is a type of engineering thermoplastic that boasts exceptional dimensional stability, stiffness, temperature resistance, and impact resistance.
	PP(Polypropylene)	Polypropylene (PP) is a material that is typically white and translucent and is resistant to corrosion while also possessing good toughness. Its most notable characteristic is its versatility, as it is suitable for use in a variety of processing methods and applications.
	PE(Polyethylene)	Polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance (minimum operating temperature can reach -100~-70°C), has good chemical stability, and can withstand most acid and alkali erosion (not resistant to oxidation) nature acid)
	PC(Polycarbonate)	Polycarbonate (PC) is an amorphous thermoplastic known for its exceptional transparency and impact resistance. It also possesses strong electrical insulating properties and moderate chemical resistance.
	PMMA(Polymethylmethacrylate)	Polymethylmethacrylate, also named Acrylic. Acrylic is a highly versatile material known for its exceptional transparency, chemical stability, and resistance to heat, cold, and corrosion.
	PEEK	PEEK boasts exceptional mechanical strength, self-lubrication, impact resistance, and flame retardancy. It is also highly resistant to acid, alkali, and other chemical corrosion, hydrolysis, wear, fatigue, stripping, and radiation.
	Nylon	Nylon is impressive mechanical properties such as heat and wear resistance, chemical resistance, and self-lubrication, polyamide fiber also possesses flame retardancy, a low coefficient of friction, and is easy to manufacture.
	PS (Polystyrene)	(PS) is a polymer derived from the monomer styrene, a liquid hydrocarbon produced commercially from petroleum. Normally a solid thermoplastic at room temperature, PS can be melted at higher temperatures for molding or extrusion before being resolidified. It is a high-impact strength, low-cost resin offering a broad array of options.
	Elastomer	Elastomers are polymers with viscosity and elasticity and therefore are known as viscoelasticity. The molecules of elastomers held together by weak intermolecular forces generally exhibit low Young’s modulus and high yield strength or high failure strain. Examples are Natural rubber, Silicone Polyurethanes, and Polybutadiene, Polyurethane plastic resin.
