Commonly used materials for vacuum casting mainly cover PU resin or elastomer systems such as PMMA, PC, ABS, PA, POM, PP, silicone and soft rubber. When customers choose vacuum casting materials, they usually need to simultaneously evaluate transparency, appearance and texture, toughness, temperature resistance, wear resistance, assembly feel, post-processing methods and small batch delivery costs.
XProdLab will combine the product use, appearance grade, structural load, usage environment, target quantity and whether the texture needs to be close to that of injection molded parts to assist customers in selecting vacuum casting material solutions that are more suitable for appearance samples, functional verification parts, market test parts and low-volume pilot production of 10-200 pieces.
PMMA (acrylic effect resin) is suitable for customers to verify transparent appearance, high-gloss surface and display-level visual effects in vacuum casting. It can be used for lampshades, light guide windows, panels, transparent shells and appearance samples. Through high-quality master mold, polishing and dyeing treatments, the light transmission and surface performance close to that of acrylic injection molded parts can be obtained.
PMMA is a common choice among vacuum casting materials if the project prioritizes transparency, visual presentation, and low-volume market validation. If the parts require higher impact resistance, snap-in toughness or long-term heat resistance, it is recommended to also evaluate PC, ABS, PA or injection molding engineering material options.

Vacuum casting is usually suitable 10-200 pieces Small batch reproduction, especially suitable for appearance samples, functional verification parts, market test parts, exhibition samples and trial production parts before injection molding.
If the quantity is only 1-5 pieces, 3D printing or CNC machining may be faster; if the quantity continues to grow and enters long-term repurchase, it is recommended to evaluate injection molding to reduce unit cost and improve batch consistency.
Vacuum casting can use a variety of PU resin and elastomer systems to simulate the effects of common plastics, transparent parts, soft plastic parts and temperature-resistant sample parts:
Engineers will recommend more suitable vacuum casting materials based on part usage, appearance requirements, assembly load, target hardness, temperature resistance and quantity.
The dimensional accuracy of vacuum replica molds mainly depends on the accuracy of the master mold, silicone mold parting, material shrinkage, part size and structural complexity. It can usually meet the needs of appearance samples, assembly verification and low-volume pilot production.
If the part has tight tolerances, transparent appearance, or functional testing requirements, it is recommended to upload a 2D drawing and mark the critical dimensions.
need. Vacuum castings will first make a master mold and then develop based on the master mold. silicone mold, and then replicate the parts through vacuum degassing and PU resin casting.
Compared with injection molding steel molds, silicone molds have lower costs and shorter cycles, and are more suitable for small batch replication and rapid verification. However, silicone molds have limited life and are not suitable for long-term mass production.
support. XProdLab can provide post-processing such as transparent resin, translucent effects, coloring, spraying, sandblasting, polishing, silk screen printing, dyeing and partial assembly depending on the appearance grade and usage scenario.
If the customer needs a texture close to that of injection molded parts, it is recommended to specify the target color, texture, gloss, transparency, LOGO and appearance acceptance criteria when quoting.
support. Vacuum casting can be carried out according to the structural position Copper nuts, metal inserts, positioning pins or partial assembly parts are pre-embedded, used to improve assembly strength, disassembly and assembly reliability, and functional verification authenticity.
Pre-embedding of inserts requires early assessment of wall thickness, force direction, positioning method and pouring space. It is recommended to provide insert drawings, assembly relationships and target torque or force descriptions.
Vacuum casting and injection molding are suitable for different stages:
If the product is still iterating, it is more reliable to first use a vacuum casting to verify the appearance, structure and market feedback; if the design has been finalized and the demand is large, you can enter the injection molding evaluation.
The delivery time of vacuum replica mold is usually determined by master mold production, silicone mold development, pouring quantity, material system, post-processing and quality inspection requirements. Common range is 5-12 working days.
Simple appearance parts, small batch quantities and standard colors are usually faster; transparent parts, spray screen printing, embedded inserts, strict appearance acceptance or when the quantity is large, the delivery time will be extended accordingly.
