What Is Injection Molding?
Injection molding is the most cost-effective way to make a plastic part at scale. The injection molding process involves injecting molten plastic into a mold tool, then ejecting the solidified part. This process quickly repeats hundreds or thousands of times, amortizing the cost of the mold tool and driving down the cost of each unit to a few dollars or less.
Since the injection molding process uses the same mold tool for each part, it offers consistent quality across every part. Injection molding also has the highest variety of materials, colors, cosmetics, polishes, and surface textures when compared to CNC machining or even 3D printing.
Xofah's custom plastic mold service provides on-demand prototype and production molding. We take a customer-first approach which means we find the right injection molding supplier within our manufacturing supplier network to mold the parts the way you need them—without design compromises—at the right price point.

Xofah Injection Molding Mold Classes
Standard injection mold tooling is defined by classes from Class 105 (prototype) to Class 101 (high volume production). These mold classes help manage expectations for both customers and suppliers on the overall tool requirements and scope.
Class 105 Mold
Under 500 cycles. Prototype only. Least expensive construction for minimal quantity of prototype parts.
Class 104 Mold
Under 100,000 cycles. Low production mold. Aluminum or MUD tooling, limited production runs.
Class 103 Mold
Under 500,000 cycles. Medium production mold. Most popular for low to medium-production needs.
Class 102 Mold
Medium to high production tooling. High-quality, steel tooling with automated features.
Class 101 Mold
Over 1,000,000 cycles. Highest-quality materials for extremely high production.

MoldTech Finishes
Range of textures including matte, swirls, lines, and patterns. Common: MT11010, MT11020, MT11030.
VDI Textures
VDI 3400 Surface Finish standard producing fine to coarse matte finishes via EDM machining.
Threaded Inserts
Installation of standard inserts in UNF and metric sizes.
Pad Printing
Transfer 2D images onto 3D parts.
Laser Engraving
Engrave part numbers, logos, and more onto parts.
Assembly
Assemble and label injection molded parts.
Custom Injection Molding Design Guidelines
| Feature | Tip |
|---|---|
| Undercuts | Reduce undercuts to decrease tool complexity and cost. Add pass-thru coring where possible. |
| Wall Thickness | Maintain even wall thickness to prevent sink and voids. Thinner walls reduce cycle time and costs. |
| Drafts | Ensure minimum draft angle of 0.5°, or up to 5° for medium textures. |
| Ribs/Gussets | Ribs should be 40-60% the thickness of outer walls and maintain draft. |
| Bosses | Design at 30% wall thickness depth with 30% edge groove. Attach to side walls or ribs. |
