Tipo de acabado | What It Does | Mejor utilizado para |
Como alcanzado | The part comes straight from the machine with visible tool marks. | It is ideal for internal parts, and when appearance doesn’t matter. |
Granallado | It gives a clean, matte look by removing sharp edges and shine. | Suitable for covers, trampas, and daily use products. |
Pulido de vapor | Makes the surface clearer and gives it a glossy finish. | We make its use when a smoother or semi-transparent look is needed. |
cayendo | Precisely smooths the part and removes small burrs from the surface. | Optimal for small parts and bulk finishing. |
Recocido (Trato térmico) | Relieves stress from machining and improves dimensional stability. | It is best for load-bearing or structural PP components. |

polipropileno(PÁGINAS) Plastic CNC Machining for Custom Parts – Tops Precision
polipropileno (PÁGINAS) is a semi-crystalline thermoplastic material. It features lightweight and excellent chemical resistance. When it comes to structural stability and reliable parts, even in moisture-rich or chemically aggressive environments, it remains a vital choice.
PP is widely used in B2B applications that demand strength without adding more weight. Its low density, resistencia mecánica, and impact resistance make it ideal for industrial-grade parts.
En la máxima precisión, we offer custom Polypropylene machined components. Our advanced facility includes multi-axis CNC mills, high-speed lathes, and laser cutters. We can handle prototypes, short-run production to mass mass-scale demands.
We facilitate a broad range of industrial sectors like automotive, construcción, electrodomésticos, dispositivos médicos, y sistemas de agua. We produce precision housings, pump fittings, cubiertas de electrodomésticos, and enclosure components.
All PP parts are manufactured under ISO 9001, YO ASI 13485, and AS9100D certifications. Every project is monitored for quality, entrega, and material performance.

Pros of Machining Polypropylene (PÁGINAS)
- Low Tool Wear During Machining:PP is a relatively soft material. It allows longer tool life and minimal cutter abrasion, even in continuous production runs.
- Chips Easily Without Melting and Gumming:We machine PP at optimal speeds. Entonces, it forms clean chips, avoiding heat buildup and smearing on tools.
- High Dimensional Repeatability in Dry Cuts: PP stays stable even when machined without coolants. This helps maintain tight tolerances close to ±0.010″ to all identical parts.
- Fast Material Removal at Low Cutting Force:PP has low hardness. It can be cut quickly with low spindle load. This allows us to reduce overall cycle time.
- Ideal for Prototyping and Custom Fittings: Its machinability makes it optimal for short runs, trials, or one-off designs where molding is not economical.
Cons of Machining Polypropylene (PÁGINAS):
- Low Melting Point Requires Precision Speed Control:High machining speed(RPMs) can melt PP at the cutting point. This leads to part deformation and gummy tool buildup if not carefully managed.
- Difficult to Hold Without Deforming:PP has high, and during machining, it can distort under clamping pressure. This makes fixturing difficult for thin and small parts.
- Burr Formation on Edges Is Common:The softness of PP can leave burrs after cuts. Entonces, you may need secondary deburring steps for fine features.
- PP is Not Suitable for High-Speed Milling:Rapid milling may cause melting, stringing, o deformación, limiting its compatibility with high-speed automation.
- Limited Surface Finish Quality Without Polishing:Obtaining a polished or glossy finish directly from machining is difficult. Entonces, surface treatments are often required as post-processing. These added extra cost to the project.

Preguntas frecuentes
Sí, Polypropylene can be CNC machined with ease. At Topsbest Precision, we use optimized cutting speeds and fixturing to machine PP cleanly without deformation or melting.
PP is highly flexible, so standard tolerances of ±0.010 mm are common. Sin embargo, our company uses an appropriate setup, so we can achieve custom tolerances for simpler to complex geometries.
Sí, Polypropylene is ideal for short-run prototypes and low-volume runs. It provides a fast, affordable solution without the need for molds.
Machining polypropylene is overall economical for large batches, as the material is readily available. This keeps its market price lower. Sin embargo, controlling machining and finishing time is important to keeping overall costs down. One way to do this is by avoiding unnecessarily tight tolerances and features.
Standard tolerances of ±0.010″ are usually enough for size and position. Tighter tolerances mean more time for machining and may cause issues of warping under heat. By designing with well-defined tolerances, you can avoid dimensional creep and reduce rework, especially in high-volume runs.
