Cost-Effective Rapid Injection Molding
Rapid injection molding provides a better choice for those clients needing low volume molded parts. It can not only manufacture hundreds of production-grade plastic parts for verification test close to the final product, but also provide on-demand production of end-use parts for low-volume manufacturing.
At Winners Rapid, we specialize in rapid molds of both aluminum and steel and low-volume plastic molding, and rush parts to you on a schedule that supports your entire testing and pre-production schedule. We blend traditional injection mold tooling methods with rapid mold tooling to provide cost-effective and rationalized advice from designs, materials, production processes, manufacturability, etc.
At the same time, when the design is stable or volumes are growing, Winners Rapid will move to conventional mold production for your benefit. Diversified solutions for custom plastic means you work with a single source for everything from prototype to production for delivery.
Advantages Of High-Volume Plastic Injection Molding
Injection molding is one of the oldest high-volume manufacturing processes. This is a specialized service offering full production-quality parts in volumes of up to millions of pieces a month. High-volume plastic injection molding allows for high-tolerance precision, low scrap loss, and cost savings.This type of manufacturing is ideal for medium and large-sized businesses or mass production.
- Produces more parts at a faster pace
- Reduce unit costs and cycle time for the manufacturer
- Accurate and consistent, high-quality mass production of parts
- Production can often be automated with solid, reliable machinery, even during non-work hours
- Minimal post-production work

Available Surface Finishes For Injection Molding
Many surface features must abide by the industry standards of the Society of the Plastics Industry, or SPI. These standards in the plastics industry identifies the cosmetic quality of plastics. The SPI standards specify 12 grades of mold finish in four different categories that range from smooth mirror-like finish to a rough dull surface.
Smooth And Glossy Finish
For the smoothest and glossiest finishes, SPI grades A1, A2, and A3 are suggested. These grades involve the use of hardened tool steel molds with a buffed mold surface using fine diamond powder. The mirror luster gives a smooth and shiny finish that is almost mirror-like. Products like visors, plastic mirrors, and optical goods are made using these sorts of finishes.
Finish |
SPI Grade |
Typical Surface Roughness Ra (μm) |
Super High Glossy finish |
A-1 |
0.012 to 0.025 |
High Glossy finish |
A-2 |
0.025 to 0.05 |
Normal Glossy finish |
A-3 |
0.05 to 0.10 |
Semi-Glossy Finish
One step below the SPI grades above are grades B1, B2, and B3 which deliver a semi-glossy finish using a hardened tool steel mold with some sheen on its surface. The mold surface is polished with emery cloth or ultra-fine grit sandpaper. The semi-glossy finish is a great way to hide machining, molding, and tooling marks.

SPI Grade |
Typical Surface Roughness Ra (μm) |
Fine Semi-glossy finish |
B-1 |
0.05 to 0.10 |
Medium Semi-glossy finish |
B-2 |
0.10 to 0.15 |
Normal Semi-glossy finish |
B-3 |
0.28 to 0.32 |
Matte Finish
Perhaps one of the most popular surface finishes is the matte finish. SPI classifies this finish type across grades C1, C2, and C3. The molds used for matte finish are polished using fine stone powders. Diecast parts, industrial parts, and consumer goods all use a matte finish. This finish not only gives a good aesthetic appearance, but also helps mask machining marks.

SPI Grade |
Typical Surface Roughness Ra (μm) |
Fine Matte finish |
C-1 |
0.35 to 0.40 |
Medium Matte finish |
C-2 |
0.45 to 0.55 |
Normal Matte finish |
C-3 |
0.63 to 0.70 |
Textured Finish
Lastly, we have the textured finish, classified as SPI grades D1, D2, and D3. The mold used for the textured finish is first smoothened using fine stone powder and then dry blasted with aluminum oxide and sometimes glass bead. A textured finish gives a good grip quality on the surface, hides deformations and marks, and at times even helps mask fingerprint smudges.
Finish |
SPI Grade |
Typical Surface Roughness Ra (μm) |
Satin Textured finish |
D-1 |
0.80 to 1.00 |
Dull Textured finish |
D-2 |
1.00 to 2.80 |
Rough Textured finish |
D-3 |
3.20 to 18.0 |
How to work Winners Rapid For Rapid Injection Moulding?
Once we receive your request for quote and engineering data, our process for injection molding is as follows:
- 1.We provide a quote typically within 48 hours
- 2.We receive your purchase order and we prepare a Design for Manufacturability (DFM) report for your approval. In that report will make suggestions (if any) to improve the part. We will also detail our strategy for the design of your mold including, gating, ejector pin placement, mold flow analysis, and project milestones. The report is typically ready 1 week after purchase order receipt
- 3.Once you approve your DFM report. We begin building your mold and depending on part complexity take will take 3 to 8 weeks
- 4.When your mold is complete we will send you the first test parts (T1 parts) for your feedback. In your quote and project plan, we will allow for 3 iterations (T1, T2 and T3) so we can incorporate your feedback and fine adjustments. We will not apply a texture to the mold until you approve the part geometry
- 5. We produce the quantity of parts you ordered and ship them to you with inspection reports and material certifications
