When the gear mechanism of the cylindrical gear is meshed and transmitted, there is a relatively large tangential relative sliding speed along the tooth length direction, which will produce a large friction and wear; on the other hand, the tooth profile of the two wheels is in a point contact state, and the contact stress The value will roughly cause the curved surface to be prematurely pressure-fed, which promotes increased gear tooth wear. Compared with parallel-axis helical gears, the service life and mechanical efficiency of cross-axis helical gears are much lower.

We sign the NDA with our customer and also for their projects. Each employee must take pre-enter company training to follow our production flow, so that keep company information security. NDA will be signed on board date. As well as for all our suppliers have to sign NDA. For date security, we use the ISO27001 as the reference. All the data will be securely kept at our own network centre, only the authorized staff can access to the centre and review the data.
We use the work order system to control each process step, timeline for each job is very clear for each team. All of customer requirements will be reflected from the work order. When quoting, our production engineers will review the data and requirement, and provide the DFM if needed. During the production, we guarantee the on-line and off-line inspection to ensure that the parts we produce meet your exact specifications.
We are ISO 9001 certified, first article inspection, also support to provide the FAI report.Before the packing, we have the final inspection, which will check all the quality details by our QC. We are very concerns the safety packing. For different sizes and materials production,we will adopt different packing methods to keep products delivery safely. Parts will be marked with labels of item no. and PO no. for customers to recognize easier.
Nowadays, 3D printing is developing in a more efficient, intelligent and rapid direction in prototypes industry. Also, 3D printing technology is becoming a trend and is slowly becoming a new way to change industries.
With the gradual arrival of the era of the big industry, the manufacturing industry is rapidly developing in a more efficient, intelligent and rapid direction. What are the advantages of 3D printing? Please see blow:
According to the structure and quantity of the parts, the rapid processing technology is adopted. PTJ can use typical low-cost rapid production tool technology to realize small batch production, so that customers’ products can be quickly listed in the most economical way.
We mill and turn some parts very quickly. Typical quantities are 1 to 200 pieces and the manufacturing time is 1 to 3 working days. We provide product developers with parts manufactured from engineering-grade materials, which are applicable to the functional tests or end-use applications.
For information on the size of parts for milling and turning and other precautions, please refer to our Milling Design Guidelines and Turning Design Guidelines.
Before investing in injection molding or mass production, you may want to test parts as close as possible to the manufactured parts. CNC machining and silicone molding are the best choices for this situation.
PTJ has the CNC precision processing equipment, including CNC milling machine, CNC lathe, 3D printer (SLA, SLS, SLM), injection molding machine, hot pot press, vacuum casting machine and other precision production equipment, and has several three-dimensional, 2.5-dimensional, scribing machine and other testing equipment.
Secondary processing is currently suitable for 3D printing parts, CNC parts, injection molding parts and carbon fiber parts.
We offer plastic and liquid silicone rubber molding and 25 to 10,000 small batches of overmolding and insert molding. The typical manufacturing time varies from 1 to 15 working days. Rapid injection molding helps product developers to obtain prototypes and parts suitable for functional testing or final use within a few days.
The price is about RMB 6000, which mainly depends on the geometry and complexity of the parts. The best way to estimate the cost is to upload your 3D drawings to our website so that you can receive an interactive quoted price within a few hours. RPS can create your molds with a small part of the traditional injection cost.
We have more than 100 kinds of thermoplastic resins and accept many resins from the customers. Check a complete list of PTJ stock resins.
We have been trying to reduce the cost of 3D parts and did not expect that we can find a supplier which can provide the same Ultem 9085CG material but the price is only a quarter of the US supplier.
Much thanks to the PTJ team for helping us to prototype the car parts, Parts are finished quickly and look very nice! We definitely will do more business with PTJ Team in the future.
Great manufacturing time, cost and quality. We needed their help in a critical moment and they have always been eager to support us with all of out requests.
PTJ have produced top quality prints for us at very short notice and with great turn around times. They have provided us with a reliable service when we have needed it.
Both my recent orders arrived in the last few days.The PTJ Inc is amazing. I only now appreciate how delicate it is and some of the issues you had in printing it. The print was very well packed and it took quite a while to blow away the shredded paper. Many thankyous.
PTJ provided a fast and top quality service. The technician was brilliant, they were hugely supportive and the final outcome was incredibly detailed.
The package arrived today and everything in perfect. Great job with the models, and the packing was excellent. Everything arrived safely. I am very happy with your high level of customer service and quality. I will definitely be back with my next order. Thank you so much.
I’ll definitely come to you when/if I need more resin prints in future!I will also highly recommend your company to a dice-making group I am part of (with 10K+ members) for excellent quality products and customer service, so hopefully you’ll get more orders!
