Product Description

What is Vacuum Casting | Urethane Casting ?

Urethane casting provides end-use, rigid plastic parts or rubber parts with production-level quality. Built without expensive and time-consuming hard tooling, urethane casting process uses a 3D printed master pattern and silicone molds to deliver high-quality, short-run parts up to 30” long. The finished dimensions of urethane cast parts depend on the accuracy of the master model, part geometry, and casting material. In general, a shrinkage rate of + 0.15% is expected.

Cast urethane parts are frequently used when color, surface quality, and toughness are required. Urethane molding is a perfect alternative for insert molding or over molding in low volumes with diverse material choices. Polyurethane casting can also be used for bridge-tooling between a 3D printed rapid prototype and an injection molding with a balance of quality, cost, and time. Urethane cast parts can also be clear, color-matched, painted (including EMI shielding), have installed inserts, and even custom finished.

Materials

Cast urethane parts are often compared to injection molding materials. For example, a stiff urethane cast part may be described as
"polycarbonate-like," and a more flexible plastic may be "polypropylene-like." We group our urethane materials into general categories to help you make quicker decisions and get the best performance on your project. The list below describes the categories of materials and technical examples when selecting polyurethanes.

Material Name	Shore Hardness	Description	Technical Information
ABS-Like	Shore D 78-82	A tough Shore 80D flame retardant material that is UL Listed with a flammability rating at 1/16" (1.6 mm).	TC-891-FR or equivalent
Polycarbonate-Like	Shore D 82-86	A stiff, high impact, high HDT, material with a wide variety of uses. Simulates polycarbonate (non-clear), Shore 84D.	TC-854 or equivalent
Glass-Filled Nylon-Like	Shore D 85	A stiff, USP Class VI, high-performance urethane with high impact strength and a HDT of 190°F (88°C).	PT8902 or PT8952 (FR)
Rubber-Like Polyurethane	Shore A 25-95	A Shore A elastomer with a high elongation to break.	F-130 to F-190 or equivalent
Clear Rubber-Like Polyurethane	Shore A 40-95	A colorless Shore A elastomer with a high elongation to break. Matte finish will give a frosted appearance, and higher gloss will increase its transparency.	WC-540 to WC-595 or equivalent
Somos ProtoGen 18420	White, ABS-like	71MPa/KSI	16%
Somos Taurus	Dark Gray, ABS-like	71MPa/KSI	24%

Size and Tolerance

Description	Tolerance Notes
Distance Dimensions	+/- 0.010” or +/- 0.003” per inch, whichever is larger, is typical. Irregular or overly-thick geometries may cause deviances or deflection due to shrinkage.
Shrink Mitigation	A shrinkage rate of +0.15% can be expected due to thermal expansion of the liquid, and the response of the flexible mold.
Surface Quality	Surface finish is externally smoothed to a satin or matte surface. Grow lines may be present on internal or difficult-to-access features. Polishing or custom finishes must be clearly defined and agreed upon at the point of order.
Feature Definition	Sharp corners and text may appear slightly rounded.
Size Recommendation	We can offer urethane cast parts as large as 30” (0.762 m) long.

Low-Volume Production

Urethane cast parts are perfect for low-quantity production—when volumes do not justify investment in injection mold tooling—as well as for first run production parts, which can be completed weeks before production tooling is ready.

Advanced Prototyping

The urethane casting process and relatively inexpensive tooling involved makes it easy and economical to make any necessary design changes. Additionally, different materials can be used with the same mold, making it possible to test designs with a variety of materials.

Market Testing

End-user functionality and a high-quality finish makes urethane cast parts ideal for consumer testing, user evaluation and concept models. Using the cast urethane process means that changes can be incorporated quickly for either further testing or market launch.

Recommend Products

MJF 3d printing service.

Multi Jet Fusion or MJF custom 3d printing technology is perfect for those times when you are looking for lower porosity, short lead
times and unsurpassed surface quality. If you are manufacturing complex end-use parts and have decided to produce it in a low
volume, then MJF can be the best option for you.

Part is made by HP printer, and has got very good strength, now it is mostly in grey black color.

Material: PA11, PA12, PA2200, PA12GB
