EXPERT IN PLASTIC INJECTION MOLD&MOLDING&PROTOTYPING
GALAXY3DM assists you in the design and manufacture of your parts and sub-assemblies in PUR materials. Our integrated offer of service in China provides you with a trusted collaboration with a single RIM engineering sub-contractor.
The RIM molding process combines liquid polyurethane resins, low molding pressures, low mold temperatures and provides the ability to mold parts of any size at economical low annual production volumes.
It can mimic the physical part characteristics of traditional injection molding, make very large parts like in fiberglass lay-up (FRP), control wall thickness and improve reliability and repeatability of typical labor intensive thermo or pressure formed parts.
These RIM advantages can be employed in a host of applications
across a diverse section of industries.
When we compare RIM and other technology in Low volume production, we may its unique advantages against other production solution.

RIM PROCESS VS. OTHERS FOR POLYURETHANE PARTS MANUFACTURING
RIM VS Injection Molding
RIM Advantages
- Approximately 70% less expensive
- Molds thick, lightweight structural parts without sink
- Varying wall thicknesses on same part
- Similar tolerances to injection molding
- Molds over metal, glass, wood, wiring, circuit boards, hardware
- Much better economies for lower volume parts
- Shorter tooling lead times
Injection Molding Advtanage
- Low Molding cost
- Shorter lead-time
- Lower high-volume per-part cost
- Colored plastic parts don’t need paint
- Finer part detail
- Greater range of material choices
RIM VS Thermoforming
RIM Advantages
- Much greater design freedom
- Lower costs for complex parts
- Higher part tolerances
- Combination of multiple parts
- Molded-in bosses, ribs and other 3D features
- Thicker, stronger parts
Thermoforming Advantages
- Less expensive simple parts
- No paint needed for single-color parts
- Generally less expensive tooling
RIM VS Sheet Metal
RIM Advantages
- Much greater freedom to design attractive, sculpted parts
- Less expensive complex or curved parts
- Generally lighter-weight parts
- Enhanced sound and vibration insulation
- In-mold painting
- Soft-touch or flexible parts possible
- Encapsulation of parts – glass, metal, wood, wiring, circuit boards, etc
- High corrosion- and rust-resistance
- Non-conductive
Sheet Metal Advantages
- Parts sometimes structurally stronger
- No additional EMI/RFI Shielding needed
- Less expensive tooling
- Lower expense for simple parts
RIM VS Vacuum Casting: Main difference include Molding quantity, material and size.
RIM (Reaction Injection Molding / Low-pressure spraying)
- Surface quality: structure, gloss and much more
- Colour with RIM procedure: depending on material and material properties, exact RAL shade possible through varnishing
- Material properties: limited range of materials
- Typical shape production: Since the moulds are subjected only to the reaction heat of the material, higher quantities can be produced for small-scale series depending on the material properties. (multiple cavities possible)
- Maximum mould sizes: As per component geometry or volume
- Maximum part volume: Variable
Vacuum casting
- Surface quality: structure, gloss and much more
- Colour with vacuum casting: close to RAL shade, exact RAL shade possible through varnishing
- Material properties: large range of PU cast resin materials, approximating the series materials, e.g. shore hardness adjustable between 30–95 Shore A
- Options: 2 C (e.g. hard–soft), inserts
- Typical shape production: approx. 25 sets of casts (depending on cast material), multiple cavities possible
- Maximum mould sizes: 900 x 600 x 500 mm
- Maximum part volume: approx. 4 l
