Frequently Asked Questions

To help shed some light on our services, here are answers to the frequently asked questions about prototyping and manufacturing.

Common Questions

Wayken gives you instant pricing and lead times for your custom parts. There are two ways get a quote and DFM feedback from our sales team.
1.Upload one or more 3D CAD file on our Get a Quote page
2.Send one or more 3D CAD file directly to [email protected]
In most cases, we respond Quotation within 24 business hours of receiving an RFQ. If the quote is delayed, we will notify you as soon as possible.

Each project is assigned a technical sales manager and a lead project engineer, who will be there from project launch to the delivery of your parts.

For quoting Wayken prefer 3D CAD file in format in STEP, IGES, X_T or STL.
2D CAD drawings with reference dimensions in format DWG and PDF.
All of the WayKen processes are dependent on good 3D CAD solid models.

WayKen rely on our reputation of working with hundreds of thousands of unique designs over many years, we always keeps customer information confidential and have a strict policy within our factory. If needed, we can sign an NDA with customers who require this documentation.

There is no minimum order quantity requirements at Wayken.Our services can support you scale from one-off prototypes all the way to mid- and high-volume production.

Our standard terms are Ex Works (EXW) for rapid prototyping and regular production orders. This means the customer is responsible for shipping, customs clearance and all other associated fees once the goods have left our premises. We also offer terms of Delivery At Place(DAP) by DHL Express air freight, customers are responsible for import duties and fees associated with international shipping. Customers also have the option to use their own shipping accounts (e.g. DHL,FedEx or UPS) during checkout if applicable.

There is no single answer to this question but a few rules apply. For customers in USA, Prototypes to be used exclusively for development, testing, product evaluation, or quality control purposes,allow for a MFN Duty Rate of duty-free import into USA(US HTS Number: 9817.85.01.). Import duties vary widely between countries, and are dependent on the type of good being imported. Most countries in the world conform to the international Harmonized System (HS) codes that categorize virtually all commercial trade goods.

Each process is different and depends on part size, quantity required, and finishing requirements. Quality prototyping parts can be made in 3-9 days. Rapid injection molding may take 2-5 weeks to complete. More complex parts requiring or other special features will take longer. As for shipping, most of our shipments are via air freight, which can take a few days from China to Europe or North America.

WayKen accepts payment in two ways:
Bank to bank wire transfer. WayKen has accounts in Hong Kong and ShenZhen, China.
WayKen can send you a PayPal invoice and you can use your PayPal account or credit card to pay.

Unless otherwise agreed upon, all new rapid prototyping customers must pay in advance, we will consider giving 30 days credit based on the order quantity after a period of cooperation between the parties.
Except in very special cases, all tooling orders require a 50% deposit in advance, even for clients who have credit terms. Typically the balance must be paid after T1 approval of samples. Terms are negotiable with each individual customer.

General Manufacturing

CNC Machining,Urethane Casting,3D Printing,Injection Molding,Sheet metal,Finishing Service.

We do not provide design services, so you will have to have a CAD file ready to use our service. You are responsible for submitting 2D and 3D CAD drawings, and we can then provide a Design for Manufacturing (DFM) review upon receiving your order.

WayKen’s in house prototype finishing is capable of providing the best post-finish including assembling & form fitting, fastening & metal inserting, sanding & polishing, blasting & brushing, painting & printing. We also offer a wide array of specialty surface treatments, including laser etching, anodizing, electroplating, chroming, chemical finishing, powder coating, etc. To provide a fast emulated prototype as same as the final product to client, we support one-stop surface finishing operations for client’s convenience.

Almost all engineering plastic and metal materials can be processed to ensure the consistency of prototype parts and mass production parts.In addition, it has high dimensional stability, high machining accuracy and high repetition accuracy. CNC machined parts are far superior to 3D printing parts in accuracy, strength, surface finish and material availability.

We equipped with advanced HASS machines from USA, our 3-axis, 4-axis and 5-axis CNC milling machines allow us have flexible capacity to handle your customized parts, no matter simple or high complex.

There is not a given set of tolerances that fits all processes and materials. In every case, the final tolerances on your part will depend on a number of factors, including but not limited to: part size, design geometry, materials, surface finish.
WayKen’s general tolerance is applied to ISO 2768 (medium) for machined plastic and ISO 2768 (fine) for machined metals. Typically, we can hold a CNC machining tolerance from ±0.005″ (±0.125mm) to ±0.002″ (±0.05mm).

Maximum part size: 1200 x 800 x 600 mm (sometimes need splitting)

Vacuum casting can be used to closely simulate final injection molded parts or finished products,it’s good option for Low Volume Manufacturing/Short Production Runs. Generally, it outputs 12-15 pieces before degradation.

Urethane resins are polymers with certain properties are similar to engineering production plastics, such as ABS, PMMA, PC, PP, PA, and so on. Casting parts can be varied from transparent, translucent to colored, and from soft rubber to hard plastic.

The vacuum equipment can hold 2.0M*1.2M*1.0M mold specifications.

We provide a standard tolerance on ± 0.15mm/100mm, with the highest precision able to reach ± 0.05 mm.

Yes, they can, and they are. While this process is utilized for prototyping more often than not, often customers will use this as a bridge tooling process to get product out into the market while production tooling is being made. For very specialized products, such as medical devices, this process is used for production as very low up-front cost is attractive for short runs. Production quality appearance and urethanes developed for the purpose of functionality make this process great for end use.

Rapid injection molding known as Rapid Tooling is one of the real injection molding way that can solve the first hundreds of Trial production before mass production. Depending on the choice of mold material(aluminium or soft steel) and part structure, normally the rapid mold life varys from several thousands shots,which would be very suitable for small series or bridge production.

Due to Wayken’s proprietary process, we always consider most suitable mold material and simplify the mold structure, the costs of our rapid mold are very competitive normally 30%-70% of Standard Steel Tooling/Automatic Mold.

Rapid injection molding may take 2-5 weeks to complete. More complex parts requiring or other special features will take longer.

We will keep your injection molding mold for reuse for 2 years. This period can be extended upon your request.

Quality Assurance

Wayken is ISO 9001:2015 certified. You can download our certificates here.

WayKen takes a proactive approach to customer’s quality concerns from the initial communication, providing cost-effective and rationalized advice from designs, materials, production processes, manufacturability, etc.
Once your order is confirmed, we will perform a full Design for Manufacturing (DFM) review to point out any issues that our engineers feel may affect the quality of your parts.
We have the ability to share inspection data with you in real-time so we can work together to address any quality issues you may have during production. All incoming materials will meet your design specifications. Final inspection reports before shipment.

We have experts and inspection equipment to provide full dimensional inspection,we can provide CMM report or 3D scanning report upon customer’s request.

We offer OQC reports upon request.If required, we can produce additional documentation on material certs, inspection reports, certificates of conformance, etc. We just ask that this information is requested upfront on the order as it becomes very difficult to get something like a material cert afterward!

Our Statistical Sampling Plan is based on MIL-STD-105E with Zero rejects as shown in Table.

"Amazing Job and Quality Work!"

Hope you're doing well. I got the part today. You guys did an amazing job! I was hoping to get quotes for the attached files. The specs are the same for all of them. Please also see the attached thread picture.
