Our professional packing standard will help you lower the risk of damaging parts during transportation.
Clean and remove oil. Use protective material on the parts individually (paper or a protective net) to ensure a spotless surface that won't scratch in the shipping.
After the individual packaging, protect the parts with air bubble packing and wrap them with adhesive tape. Then place custom labels so that you can distinguish them.
Our team will offer free DFM as per every project and if the material you choose is not the best choice for your project, we will suggest you some materials for you to choose from.
Normally, we will quote as per the tolerance standard mentioned on 2D drawings. For CNC metal parts, we will proceed with ISO 2768-F while for plastic parts, we will proceed with ISO 2768-M if no special requirement. Any crucial dimensions should be mentioned on the 2D drawings or to our project engineers directly.
For testing, 3D printing is fast and cost-effective. But for structural testing, 3D printing may not be a good choice as the quality is not very stable. CNC machining will proceed the part with one piece of raw material, so it is more suitable for structural parts. There are few available finishes for 3D printing. You can have more options with CNC machining.
Indeed hourly price for 3-axis CNC is much lower than for 5-axis CNC. When we quote, we compare the cost of multiple machining plans and choose the best solution. If some features are impossible to proceed with the 3-axis or other machines, we have to proceed with the 5-axis.
For turning parts, we can make them with 2D drawings. For milling parts, our engineering team can work out 3D drawings for your checking then. If the drawing is confirmed, we will proceed accordingly.
It will depend on the structure of the design. If the part is a simple lathe part or CNC part, it may be more cost-effective to proceed with machining.However, if the structure is kind of complex and may need 5-axis CNC to make it, prototype molding will be a better choice in this case.
Yes, we can offer design services for those companies without their own design team. However, for this issue, it will take longer communication time and once the need is fixed, we will charge you before we proceed with the drawing for you.
The parts will follow self-inspection, mutual inspection, and final inspection in TurnkeyModel. When the parts move to the next process, the parts will be tested again to make sure the previous processes are okay.Before we ship out the parts, our QC team will take strict quality inspection all over and only ship them when everything is okay.
If the parts are not available for your requirements, please kindly contact us once you found them(We ensure 30-day-guarantee) and send us some pictures or videos with our official claim report, which will help us find the result for the issue. All detailed information about the claim issues would be sent within 3 working days.
We fully understand sometimes it is hard to choose a suitable material. In this case, you can share all the details about your design with our project engineer, for example, usage, function, working conditions, and anything related, then our project engineer will come back to you with DFM and suggest you some options for you to decide.
Manufacturing parts is not our goal, our value is helping customers grow their businesses. The engineering team with 20+ years of work experience provides free DFM reports with you to help you reduce procurement risks and manufacturing costs.
Analyze manufacturing risks
Optimize part design
Improve machining efficiency
Save processing costs
Control production quality
Whether the material could be bought
Whether the material is okay to be machined by CNC
Whether the material is available for customers’ chosen surface finish
Analyze if dimensions from 2D and 3D drawings did not match
Analyze if the surface roughness can meet the requirement
Analyze whether the parts need to be assembled together
Analyze if the structure of part is suitable for CNC machining
Analyze whether the wall thickness, hole, undercut, inner right angle features can be machined by CNC machining
Whether dimensional tolerance and tolerance of form and position can meet the requirement
Whether the part will deform and influence dimensional tolerance during machining and welding
Whether the surface finish process will influence the dimensional tolerance
The structure of the part is the biggest factor influencing the machining cost. Why is the cost control of your competitors more advantageous? You are just overlooking some details.
The cutters are round and cut off the extra material by rapid turning of the blade. In this case, there is nothing the cutter can do about right-angle features. If the right angle feature is a must, it will cost you more money on it. Changing the inner feature to be radial is the best solution to lower cost if it does not influence further assembly. Ideally, the internal fillet diameter of plastic parts is at least 1 / 9 of the cavity depth. The aluminum parts shall be at least 1 / 8, and the steel parts shall be at least 1 / 6 of the cavity depth.
Thin walls are fragile. If the cutter moves too fast, the thin walls will be rough due to the cutter bounce. The distance between holes and edges should be enough. Ideally, the distance from the hole to the edge of the plastic part shall be at least 0.8mm, and for the metal part, it shall be at least 0.5mm.
Deep cavities need to move away a lot of excess material which increases machining costs accordingly. Sometimes we have to make a customized cutter for the features and it will also increase the cost. Ideally, the maximum depth of cavities for plastic parts shall be 9 times the diameter of the cutter. For aluminum parts shall be 8 times while for steel parts shall be 6 times. The minimum cutter diameter is determined by the inner radial feature diameter. For example, if the inner radial feature is R1, the minimum cutter diameter which can be used is R1.
Undercutting often requires custom cutters. The cost of cutters will be added to the machining cost as well. So, only make it when absolutely necessary.
Deep holes have high requirements on the strength of the reamer. Ideally, the maximum hole depth of plastic parts shall be 10 times the diameter of the reamer. The aluminum parts shall be 8 times, while the steel part shall be 6 times. If your design is out of scope and requires custom cutters or process change, there shall be an extra cost.
Too long threads will not make the assembly tighter or closer. If the hole depth is greater than 3 times the hole diameter, the tap will have a break risk and we will spend more time on the deep hole. In fact, a thread depth of 1.5 times the diameter is enough to assemble the part securely.
Our ability is CNC machining, sheet metal fabrication, injection molding, die casting and so on. No matter what stage of development you are in, you will find a solution at TurnkeyModel.
