2. VPC Pneumatic Cylinder Customization Process

① Customer Requirement Collection

We accept both drawings and used part samples. Whether you provide CAD drawings, a single used cylinder that needs replacing, or other customized requirements, our technical team will provide professional support:

• Parameter confirmation: Confirm parameters such as cylinder diameter, stroke, installation method, and operating pressure.

• Used part measurement: If you don't have drawings, you can send us an old sample, and we will perform reverse engineering to reconstruct the data.

• Operating condition matching: For specific operating environments, our engineers will optimize the sealing components and material selection.

② Raw Material Selection and Display 

We control the source and ensure material traceability. Before production, we can provide you with real photos or material certificates of the raw materials:

• Cylinder tube: High-precision aluminum alloy or stainless steel tubing, with a hard anodized inner wall for wear and corrosion resistance.

• Piston rod: High-frequency quenched and hard chrome plated material to ensure high hardness and smoothness.

• Seals: Imported brands or high-performance domestic parts (NBR/fluororubber) are selected according to requirements.

③ In-house Precision Machining

We have our own independent cylinder machining workshop, equipped with high-precision CNC machine tools. This means we have complete control over machining accuracy and production schedule:

• End cap machining: Precision turning on CNC lathes ensures perfect fit with the cylinder barrel.

• Detail processing: Chamfering and thread finishing are meticulously executed to eliminate burrs.

• Transparent process: This is our core advantage—if you need to know the progress of your order, we can record short videos of the machines processing your product at any time, allowing you to see the production process firsthand.

④ Standardized Assembly

After component machining, components enter the clean assembly area:

• Cleanliness: All components undergo a second cleaning before assembly to prevent metal shavings from damaging the seals.

• Lubrication: The amount of grease applied is strictly controlled to ensure smooth piston movement without jamming.

• Tools: Specialized tooling is used for assembly to avoid violent impacts that could deform the cylinder block.

⑤ Quality Inspection Process

Every cylinder undergoes rigorous testing before packaging, with all cylinders meeting full inspection standards. We are happy to provide you with live video footage of our quality inspection process:

• Air tightness test: Pressurized air is applied, and the cylinder is submerged in water or tested using precision instruments to ensure no internal or external leaks.

• Operational test: Simulating actual operating conditions, the cylinder's expansion and contraction are tested to check for smooth operation and effective cushioning.

• Visualized inspection: For bulk or critical orders, we can record a complete test video before shipment and send it to you, allowing you to "monitor remotely."

⑥ Packaging and Delivery

We offer worldwide shipping services and include after-sales documentation such as installation recommendations, maintenance guides, and instructions for spare seals.

3. FAQ

Q1: Is there a minimum order quantity (MOQ) for custom cylinders?

We fully support everything from single-piece sampling and small-batch trials to mass production.

Q2: I only have a damaged old cylinder, no drawings. Can you still make one?

Absolutely. You can send us your old sample. Our technical team will disassemble and reverse engineer it to reconstruct the drawing parameters and begin production after confirmation.

Q3: How long is the lead time for custom cylinders?

Standard non-standard customization is generally completed within 3-7 business days after drawing confirmation (depending on the complexity of the process). For urgent orders, please let us know directly, and we can coordinate with the production line to prioritize them.

Q4: I can't be on-site. How can I ensure the finished product meets my expectations?

We provide full-process visualization services. From raw material warehousing and CNC machining to the airtightness testing of the finished product, we can send you high-definition videos or photos for confirmation, giving you peace of mind.

Q5: Can you manufacture cylinders for special environments (high temperature/corrosion resistant)?

Yes, we can. For high-temperature environments, we will replace the fluororubber seals and use high-temperature resistant grease; for corrosive environments (such as food and chemical industries), we offer customized solutions using all stainless steel (304/316) materials.
