Vacuum Casting Rapid Prototyping Of Small Production Runs For ABS
Polyurethanes
Vacuum Casting :
Polyurethane vacuum casting is a specialized method used to create
accurate replicas of master patterns. This involves using
affordable silicone molds and liquid casting resins. The resulting
copies exhibit similar quality to plastic injection-molded parts,
but they are much quicker and cost-effective to produce.
Industries involved:
Robotics, UAVS(unmanned aerial vehicles, medical equipment, plastic
enclosures, Eletrical products, phone cases, auto parts, Household
appliances, sporting equipment,etc.
Benefits Of Vacuum Casting
Vacuum casting offers efficient manufacturing of intricate shapes
with high precision, cost-effectiveness, and versatility:
- Easily create complex shapes with precision.
- Simultaneously produce multiple components for enhanced efficiency.
- Rapidly prototype using quality urethane for small batches.
- Diverse material properties with different polyurethanes.
- Economical manufacturing due to low polyurethane costs.
- Efficient silicone mold production compared to metal molds.
Urethane Casting Tolerance Guidelines:
| Maximum build dimensions | The size of the mold is limited by the dimensions of the vacuum
chamber (1,900 x 900 x 750 mm) and by the volume of the product
(maximum volume: 10 liters). |
| Standard accuracy | ±0.3% (with a lower limit of ±0.3 mm on dimensions smaller than 100
mm). |
| Minimum wall thickness | At least 0.75 mm to ensure the mold is filled properly; for best
results, a wall thickness of at least 1.5 mm is recommended. |
| Surface structure | High-quality surface finish comparable to injection molding. |

Vacuum Casting Process
Creating polyurethane vacuum cast parts involves three main steps:
master pattern creation,
mold fabrication, and part casting.
1. Master Pattern Creation:
Crafting patterns from your CAD designs is the initial step. These
3D solids are made through CNC machining or 3D plastic printing
like SLA/SLS. You can provide patterns or let us create them.
Patterns should endure up to 50°C heat.
2. Mold Fabrication:
Liquid silicone forms the casting molds. It's poured around the
master pattern within a casting box, cured in an oven for 15 hours.
Afterward, the mold is opened, and the master pattern is removed,
yielding a negative cavity mirroring the original. Our silicone molds typically yield around 25 copies of the master
pattern.
Vacuum Casting Materials:
Acrylic-Like |
Acrylic-Like is a rigid and uncomplicated polyurethane plastic
designed to mimic acrylic (PMMA). It's used to craft components
that need some level of translucency, such as light panels, safety
screens, and automotive taillights.
|
ABS-Like |
ABS-Like is a versatile polyurethane plastic that imitates ABS
thermoplastic. Widely used, it's a reliable option suitable for
various parts.
|
Opaque Elastomer |
Opaque Elastomer is a polyurethane plastic designed to replicate
diverse rubber-like substances such as TPE, TPU, and silicone
rubber.
|
Waterclear Elastomer |
Waterclear Elastomer is a urethane casting substance that mimics a
variety of rubber-like materials like TPE, TPU, and silicone
rubber. It's particularly suitable for wearables, gaskets, and
overmolds, and is offered in a range of hardness levels from Shore
30A to Shore 80A, with increments of 10A.
|
Vacuum Casting Finishing
Glossy paint | High-gloss paint is renowned for its exceptional shine and ability
to reflect light, creating a surface finish that imparts a nearly
mirror-like appearance to objects. |
Transparent | This method allows for achieving exceptional transparency and
purity in high-purity plastic materials used for components,
combined with a polishing process. |
Soft-touch | This technique involves the application of a soft-touch coating
surface finish to elements like rubberized buttons and coatings.
Primarily utilized to enhance the ergonomic comfort of the product. |
Painting
| A simple process that applies a color to your parts, we have a
large range of colors and styles. |
Laser engraving
| Utilize laser beams to modify object surface characteristics and
personalize components according to your preferences. |
Screen printing | Screen printing serves as a versatile printing method for ink
transfer onto surfaces. Operators skillfully employ tools such as
paper and a squeegee to execute this process. Additionally,
stencils can be utilized strategically to block ink transfer to
specific areas. This technique is particularly valuable for
creating intricate designs with multiple colors. |
Tampography | Pad Printing is an innovative technique for imprinting a 2-D image
onto a 3-D object. This method involves utilizing an etched plate,
often referred to as a cliche, in conjunction with a specialized
pad to seamlessly transfer the desired image. |
