What is Urethane Casting?

Urthane Casting is a process of 3D printing or CNC machining a “master pattern” to create a mold of silicone gel, which will then be used to cast identical parts using a urethane. Parts manufactured with this process require tooling, a master pattern, and urethane part material.

It can create both flexible items that are almost rubbery in texture, and very rigid plastics.

Urethane cast parts’ quality is very close to injection molding. But faster and more cost-effective for low-volume parts.

Urethane Casting Materials

Urethane cast parts are often compared to injection molding materials. For example, a tough urethane cast part may be described as an ABS-like, PC-like, or Nylon-like part. A soft and flexible material is described as “TPU-like or Rubber-like” . So our materials will be described like this.

Material	Highlight	Tensile Strength (Mpa)	Elongation %	Bending strength	Deflection temp.（0.45Mpa,℃)	Young's modulus in flexure(Mpa)	Impact strength	Hardness	Cost
ABS-like	Dimensional stability & impact resistance	73	16	78	80	1790	12	80D	$
PA-like	High impact strength & stiffness. Can be reinforced by CF or GF	85	5	150	95	3800	30	80D	$$
PC-like	Impact-resistant, water-clear as Acrylic	73	13	117	85	2600	100	80D	$$
PP-like	Long-lasting, flexible	36	40	50	80	1300	25	75D	$
Rubber/TPU	Flexibility, high tear strength, versatility	17	430	–	70	–	–	30A-95A	$$$
