What Some of Our Clients Say...

"First off, I would like to say that it is a pleasure to work with you and Bill of the Titoma organization. You are prime examples of what it takes to make a company a world class end to end manufacturing organization that meets or exceeds needs of its customers. Hats off to you and your owners!"

- Russell Huffman, New Tech Alarms

"I am honored to testify as a satisfied customer. I'm very happy with the work you did during the manufacturing phase, and especially grateful for the attention you gave me during the whole process."

- Edgar Orozco, AVICORVI SA

"We decided to work with Titoma because of their reputation and competitive price. We saved up to 100% higher on NRE (Non Recurring Expenses, i.e. design and molds) and 50% on parts. They delivered full turnkey development with impressive professionalism and quality. We have further products lined up for the coming year, and we will look forward to working with Titoma again."

- Michael Jones, Nigami Enterprises

"I recommend Titoma as an excellent partner for die-casted and injection molded parts. During the whole process we had very fast communication, and Titoma offered many useful suggestions on how to improve our mechanical design to avoid problems. The resulting parts were beautiful with a nice finish, and they managed to achieve the tight tolerances we required."

- Jacek Rydzewski, Grupa Techniczna

"We used to buy our custom made keyboards directly from a factory in Taiwan. Unfortunately, working with them turned out to be a major headache--endless shipping delays, which cost us a lot of customers. Two years ago, we asked Titoma to select and manage a new factory. Having a team on the ground that really understands quality and is able to make decisions on the spot saved us a lot of time and hassle."

- Henk Smit, BNC Distribution


Quotes for China Plastic Production

In most cases, 3D CAD data (provided by you or generated by us) is required in order for us to prepare an accurate

If you do not yet have 3D CAD data, the Titoma Group is very well equipped to generate this for you; our design department specializes in optimizing plastic parts for low cost injection molding in China.  You can just send us what you have: sketches, 2D files or sample parts, and we will give you a rough initial estimate. If the estimate is acceptable we then charge only a nominal fee to build a 3-dimensional computer model and
optimize the parts for low cost manufacturing in China at the same time in order to lower the eventual cost of the tool.  For 2D data, AutoCAD (.dwg) is the most popular format and may be acceptable for parts with a relatively simple geometry; in fact, for metal stamping parts it is still quite common to use 2D data.

 Preferred file formats for 3D CAD data include:

  • ProEngineer
    This software is the de facto standard for 3D data in Taiwan & China.
  • SolidWorks

  • IGES

  • IGES is a general 3D export format (such as .jpg for pictures), which every tool maker in China can read and use. It can help avoid issues with incompatible software versions. The disadvantage of IGES is that data cannot be very easily changed as information is lost during the IGES file creation process. ProEngineer and SolidWorks are easier to work with if design changes are necessary.

We recommend compressing your files before sending them (using ZIP or similar). IGES files in particular can often be compressed to 10% of their original size. 

In order to prepare a binding quote on a tool, The Titoma Group asks for responses to the following basic questions:

1. Export vs. Local
Is the tool destined to be used in China or in your own country? If Titoma fabricates the parts for you in China, we can offer you much cheaper tooling prices (sometimes half as expensive) because local Asian components can be used. This includes for example Yudo hot-runners from Korea, offering better quality than DME and very good service. Imported hotrunners like those made by PSG sell in China for as much as 6 times the European price.

For export tools Titoma will need to know exactly which injection machine the tool will be used on and in which geographical area. We build tools with any Western brand name components you specify, which makes repairs and replacements simple.

The general export tooling process is as follows:
1. We design the mold according to your verified, approved specifications
2. The tool is built
2. We manufacture sample parts on our injection machines, and also make you a video so that you can see the tool in action
3. Upon approval of sample parts, tooling balance is due
4. Tool (and optional first lot of plastic parts) is shipped (normally via sea freight)

2. Lot Size
How many plastic parts will be ordered in each lot? Most injection molders prefer runs of at least 5,000 pieces, but short runs are also available.

The problem with short runs for injection molding is that for each production run the tool must be taken out of storage, mounted on the injection machine, warmed up and tuned. In general the first 30 injection shots are wasted, and after use, the melted plastic must be cleaned out of the machine for the next run. For these reasons, costs can go up quite a bit for short runs, so we always recommend that our clients combine lots together as much as possible, which also saves on transportation.

For production orders worth less than US$ 5,000 Titoma normally charges a setup fee of US$ 400 per tool per run, although for large tool packages Titoma sometimes offers the first run as part of the tool test procedure, so the fee may not apply for that first run.

3. Required tool life
How many parts do you need the tool to be able to make in the coming years? A standard P20 steel China tool can offer around 200,000 cycles, but with harder grade/hardened steel, the tool can often do a million or more.

4. Do you need Rapid Tooling?
Titoma can do rapid tooling using our proprietary modular tooling system, resulting in real tooled plastic parts in 2 to 3 weeks. We can use aluminum (soft, quick to mill) or P20 steel (the standard in China) or even S7, a very hard, long lasting steel. These rapid tools are guaranteed to produce 50,000 cycles, but in practice can often do close to 100K. Normal tools take 5 to 6 weeks in Taiwan and 6 to 8 weeks in China. 

5. Cavities
If you wish to produce a lot of parts per month, Chinese Plastic Injection Molding can provide a tool with 2, 4, or 16 cavities. For example, for a tool with 2 cavities, each time the plastic injection machine runs a cycle of injecting, cooling, opening, and pushing out parts, 2 plastic parts would be made instead of one. Multiple cavities multiply speed and they also reduce costs because less machine time is used per part and less plastic is wasted. A 2-cavity tool costs roughly 1.6 times as much as a 1-cavity tool.

6. Choice of Plastic
It is important for us to know beforehand which kind of plastic will be used to make your parts, as different kinds of plastic have different shrink rates. The 3D models our engineers make are exactly the size the final parts should be, but the tool makers actually make the tool core slightly larger, so that when the hot plastic cools and shrinks, parts of the correct size will result. If changes are made to plastic types after tool design, tools may need to be reworked, and charges are incurred during this process. 

Many of our clients use ABS plastic, and there are also many others such as PP, PET, POM, rubber, etc. to choose from. We can also add glass fiber to give parts extra strength.

The choice depends on what you need the parts for, and under which circumstances the plastic parts will be used.  The choice of plastic also affects the parts and tooling in several ways; for example, the use of plastics filled with glass fiber will shorten your effective tool life because the fibers erode the metal.

Our engineers are happy to give you advice in this choice. If you are uncertain about the type of plastic you desire, Chinese Plastic Injection Molding can first use a CNC machine to mill prototypes of your parts and then make replicas in different kinds of plastic using a silicone rubber mold.

7. Complete contact details
We will need your company address, telephone number, and email address. Does your company have a website? Who do you wish us to communicate with for various types of information requests?

The preceding information is a summary of what we normally need to ask before providing quotes. Please do not hesitate to ask if you have further questions about what Titoma may require in order to best serve your needs.

We look forward to getting to know you better and serving your tooling needs.
