23. What kind of CAE does SAIJO INX use?
We use the analysis software such like thermal fluid analysis (SolidWorks, FlowSimulation), heat conduction analysis (femtet), stress analysis (femtet) and etc. If you have any questions, please feel free to contact us.
24. How long does it take for delivery?
Lead-times: 7 days on average. At minimum: the same day. At maximum: about 3 weeks (it depends on designs). Deal with about 500 products per month.
25. Is there a processing-range limit for the original simple die-sets system?
We have 1300 dies, which are standardized. However each die is for one product according to shape, material and method.
26. What is parts' menu?
It is a list of key parts that we made a receipe for making advantages such as Quality, Costs, and Delivery. It is accumulation of techniques and know-how. It facilitates low-costs, short delivery and same precision whoever makes.
27. Can I buy die-sets for prototypes?
If you are requesting die-sets for a prototype, please contact us.
28. What is the life- expectancy of original simple die-sets?
It is from thousands to tens of thousands in case of a grade of pre-production-die. However it depends on the shapes and materials. Please contact us for further information.
29. How long does SAIJO INX usually keep the original simple die-sets?
For 1 year after the final production. SAIJO INX certainly have confirmation and approvement from customers in disposing. Die-life does not last 2 or 3 years. As a die-maintenance is not scheduled, rust would come out. In such a case, if you demand to reuse the die-sets, die-maintenance-costs would be incured separately.
30. Is it possible to acquire the original simple die-sets and/or die-designs?
Since they are completely original, we keep it in-house only. However if requested a contract can be made for such cases. This will ultimately increase the die-price, so we don’t recommend it to persons who need inexpensive prototypes.
31. Can I have a confirmation of receipt of dies for asset management? And can I also have the dies?
YES. Confirmations of receipt for prototype and mass production will be issued on the model of your company. As for the original simple die-sets, it will be issued for the only exterior. And they are managed only in-house. You can issue for the die-sets except the original simple die-sets. In that case, die-sets costs are required.
32. What kind of materials does SAIJO INX usually use for insert molding for prototypes?
PA,PC,POM,PBT,PPS,LCP, and so on. We cannot deal with thermosetting resin and PEEK in-house but with our network it may be possible to produce, contact us.
33. What software does SAIJO INX have for designing injection-molds?
We use the software (TOPsolid) of KODAMA Corporation, Ltd.
34. How long does it take for processing metal/resin mold?
Less than 10 days on average by the consistent production system in-house. If you need core pins of housing, contact with us.
35. How long does it take for the original simple die-life?
3000 shots but it depends on the materials and the shapes of simple dies and the parts, contact us.
36. How many does SAIJO INX produce prototypes of metal/resin sets?
From one (an initial prototype) to ten thousands, but it depends on the grades of simple molds.
37. Does SAIJO INX suggest developments of outsourcing, cooperation and method?
YES. But if it corresponds to first contacts and costs. Contact with us.
38. What is LLP?
It means Limited Liability Partnership. It makes easier to start up business, cooperate companies and industries, that have various techniques and know-how.
39. What kind of method of processing by microscopic lasers?
It is shearing of blank and holes. As programming is enough to process, it enables to produce from one work. And that makes easy to change the programming. It is used for manufacturing layerd-dies. It is suitable for trial and error. The materials are mainly iron and steel, nonferrous metal(except copper more than 0.3mm). And from 0.05mm plating thickness is achieved.
40. How does a wire EDM work?
It works by creating an electrical discharge between the wire and the work-piece. It takes much time but it makes high-precise processing.
41. What kind of method of processing by etching for thin sheet metal?
It works by using strong acid to cut into the unprotected metal surface.
42. Can I supply parts after disposition of mass production-dies? And how can I have a space for the dies?
YES. The original simple die-sets enable to process precisely and provide low-costs. And since they are disposable, you need not space and period for dies. If you need to supply parts, it enables to produce quickly and to reduce costs for dies.
43. Can I have fin-samples ?(Corrugated fin, Offset fin, and etc.)
Yes, you can try many kinds of SAIJO original standard fins that are low cost on short delivery time.
Please contact us, if you’d like to evaluate your products with thin sheet metal fins. And also, as for selectable dimensions and available materials, please feel free to inquire.
44. Can I ask without design?
YES! A rough sketch or just an image, whatever. Contact with us.
45. What kind of business segment for mass production does SAIJO INX have?
Optical transmitters, Sensors, relays, terminals, basburs, and so on.
46. Can I buy molds for mass production?
No. We basically sell components.
47. How many lots of mass production does SAIJO INX produce?
From ten thousands to hundred thousands lots. It is possible to respond the other lots of products, consult us. As for lots from several thousands to several millions are minor to produce because of the range of facilities.
48. Does SAIJO INX deal with mass production, which has already done the trial stage?
YES, when it comes to thin sheet metal parts, there is no problem. But there are advantages and disadvantages of facilities capability. Consult us. As for insert molding, we will respond with cooperation companies.
49. How many life-shot does mass production-dies have?
From hundred thousand to 3 hundred thousand (or more than 30 millions) shots for single die press. From million shots for progressive dies(SKH). It depends on shapes and materials, but if the dies are coated, it enables to use from 5 million to 10 million shots.
50. What kind of method for processing sheet metal does SAIJO INX have?
Die blanking, hole-punching, drawing and bending for stamping. Single press, progressive press and both are chosen according to types of press. We propose a rational method , contact us.
51. Can I save costs instead of cutting?
YES. SAIJO INX suggests stamping. Contact us.
52. Can I save costs in stead of die-casting?
YES. SAIJO INX suggests stamping. It enables to reduce a unit price, to save weight, to supply stably and to realize repay dies (part sharing) by assembling parts. Contact us.
53. Can I change the length of products in the same shape and pitch?
YES. SAIJO INX suggests to cut by stamping. It enables to reduce the number of die-sets. Thus it means also reduce the initial costs for dies. Contact us.
54. Can I save costs of die-casting, MIM, or cutting?
YES. SAIJO INX suggests to layer by stamping. It enables to reduce cost and to realize solid shapes by revising partial layered shapes. Contact us.
55. Can I save cost for producing heat sinks instead of extrusion, die-casting, or cutting?
YES. SAIJO INX suggests stamping. Contact us. It enables to increase surface area, to realize complex shapes, to process with copper etc.(aluminium, stainless steal, iron), to improve productivity, to supply stably and reduce cost. Contact us.
56. What is one-shot drawing?
It is the original method which is added slits to the material before processing. Since there are slits, the bottom is strong but cannot be sealed. For detail, contact us.
57. Can I reduce man-hours of pin-caulking?
YES. SAIJO INX suggests stamping which produces efficiently. Contact us.
