Surface Finishes for Blow Molding

NOBLE can help improve the surface qualities of your products by offering a diverse range of surface finishes. Surface finishes on your customized parts aim to improve their appearance, surface hardness, and roughness, chemical and corrosion resistance, and so on. Here are some of your best options.

Anodizing

Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.

Materials: Aluminum

Color: Clear, black, grey, red, blue, gold.

Texture: Smooth, matte finish

Powder Coating

Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.

Materials: Aluminum, Stainless Steel, Steel

Color: Black, any RAL code or Pantone number

Texture: Gloss or semi-gloss

Electroplating

Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.

Materials: Aluminum, steel, Stainless Steel

Color: N/A

Texture: Smooth, Glossy finish

Polishing

Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.

Materials: Aluminum, Brass, Stainless Steel, Steel

Color: N/A

Texture: Glossy

Brushing

Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.

Materials: ABS, Aluminum, Brass, Stainless Steel, Steel

Color: N/A

Texture: Satin

Check the feedback of our valued customers on how we build strong cooperation relationships with our expertise and the best customer service.

Communication was prompt, professional, and helpful. Design changes were accommodated quickly and with no hesitation. The completion of manufacturing was very fast and shipment was quick as well. We are very happy with the result and will certainly use NOBLE again in the future.

cI was impressed with the sample models I got from NOBLE. Their team worked with me to spot a few issues with the initial design, which saved time and money since we avoided producing parts with the defects. I have put in another order with them. Great to work with.

I’ve been working with Kevin and the team for 3 years now for prototyping and early-stage development, and it couldn’t have been better. On-time, professional, fast turnaround, continuous availability and updates, and most importantly, extensive review before any part is put into production. I am always impressed by the tight tolerances achieved even on the largest parts

We are very satisfied with the services provided by NOBLE. Their team is responsive and professional, and the products are always of impeccable quality. Working with NOBLE has been a smooth and pleasant experience, and we highly recommend them to any company looking for custom manufacturing solutions. Thank you for your excellent work!

Blow Molding FAQs

What is the blow molding process?

Blow molding is a process that produces hollow parts by forcing the plastic against the mold walls through the use of air pressure. This process is primarily used to create containers such as soda bottles and milk jugs, but blow molding is not limited to the formation of only containers.

What is the advantage of the blow molding process?

Extrusion blow molding uses a relatively lower level of pressure. This reduces the expenses incurred in the production process and makes the product cost-efficient. Also, the use of the blow molding process will allow manufacturers to minimize high labor costs.

Where is blow molding used?

Blow molding plastics is a manufacturing process that uses air blown into a mold cavity to create a hollow component. It is commonly used to make parts for the construction, industrial, automotive, medical, and packaging sectors, among others.

Why is blow molding so widely used as a manufacturing process?

Compared to injection molding, plastic blow molding typically has a lower tooling cost. Likewise, many different materials can be blow molded, making it an appropriate process for a wide variety of applications.

What is the difference between blow molding and extrusion?

Blow molding is a specialized type of plastic processing used to create hollow plastic parts. The extrusion form of blow molding is a manufacturing process whereby plastic is melted and extruded into a mold. This process is specific to producing a high volume of hollow, one-piece objects.

How can I reduce the cost of my machined parts?

The main costs associated with CNC machining can be grouped into machining time, start-up costs, material costs, and feature costs. To reduce costs you need to understand the impact of these factors on cost.

1. The best way to reduce machining time is to design features that can be machined quickly, for instance, choosing the correct radii for internal corners, reducing cavity depth, increasing wall thicknesses, limiting thread length, and designing holes with standard sizes.

2. Material costs can be reduced by considering the size of the blank required, and the cost and machinability of the bulk material (softer alloys are faster to machine).

3. Start-up costs can be reduced by reducing the number of part rotations or repositioning required to finish the part, for example, separating geometries into multiple parts that can be assembled later.

4. Feature costs can be reduced by only using tolerances when strictly necessary, removing all text & lettering, and avoiding multiple surface finishes.

How do you guarantee the machining quality of my parts?

Our sound quality-control system makes sense that thousands of customers place their CNC machining orders in our company. The regular check and testing start from incoming materials to shipment, ensuring each part is produced accurately for your specifications.

We possess a comprehensive, standardized inspection report with every order to ensure quality metrics are being met, and offer a first-article inspection service on orders of 100+ units. We also have multiple certifications available on request, including but not limited to ISO9001 and ISO13485.

What kind of a finish does CNC machining leave?

Due to the spinning motion produced by the CNC milling machine’s cutter, the surface finish of CNC machined parts will have visible tool marks. If you require a smooth, unblemished finish for your parts, we recommend choosing a secondary finish: grained finish (can only be applied to the outside of machined enclosures due to geometry) or powder coat.

What industries use CNC machining?

CNC machining is widely used across a wide range of industries. It is common in aerospace, automotive, consumer electronics, robotics, agriculture, and other fields that frequently use metal parts. It is also widely used in medical devices, household goods, energy, oil and gas, and other consumer applications. It is one of the most common processing methods in the manufacturing field.

NOBLE has offered ultra-precision CNC-crafted components for global industries including oil and gas CNC machining, medical instruments CNC machining, optical CNC machining, tool and die parts CNC machining, motorcycle components CNC machining, electronic enclosures CNC machining, automotive parts CNC machining, etc.

What are your maximum dimensions for CNC machining?

NOBLE can accommodate prototyping and production of large machined parts, plastic or metal. The maximum size of our single piece is 2000mm, and the single-piece proofing can reach hundreds of thousands of batch processing and production.

What are the tolerances of machined parts?

We can provide critical tolerance according to your actual demand. For CNC machining, we manufacture metal parts as per ISO 2768-m and plastic parts as per ISO 2768-c. Please note that the higher tolerance needed, the cost will be higher.
