Plastic injection molding quotation

Plastic injection molding quotation

 

If you just start up to purchase custom plastic injection molding parts. This page is very useful for you. Also if you would like to purchase moderate price of plastic injection molding with high quality and nice service, this page is also very useful. Majority of buyers did not offer the same specification for plastic molding inquiry, then they answer different questions from different molding suppliers. As molding factory offer based different molding specification, you get big different price.

 

Plastic injection molding quotation

 

Before plastic injection molding, you know you should purchase a plastic injection mold to form the plastic injection molding parts. Then you should consider the plastic injection mold cost first. Generally there is correlation between injection mold price and plastic molding cost.  You should read full of this page to understand how to choose the suitable solution for yourself.

To have moderate plastic injection mold price

 

To choose right mould steel is the first step to have moderate price for injection mold. You should consider the production qualities, resin and color etc. We have a page on our web “Choose right mould steel for injection mold making“. From this page, you will have right ideal to choose the correct and moderate solution.

If you have different color for plastic injection molding, please kindly read this page“Plastic injection molding color quantities affect the unit price” and “Plastic parts color affect the injection mold layout”

In case you have different parts in one mold, you can review page “Family mold to reduce the mold cost” .

Except for above, multi-cavity mold is a good solution to reduce the unit price for plastic injection, it depends on that how many quantities you need to produce. Generally should assure the injection machine to run 5 days in 24 hours at leat, then it is a best solution to have reasonable unit price and mold cost for you. But you can accept higher unit price and lower mould cost, you can consider to use less cavities. You can inquiry with your plastic mould supplier with different cavity to compare the price. If you can tell your plastic molding factory how many quantities you need to order each time and how offen you will order each year, then it is easier for molding manufacturer to offer moderate injection mould price and injection moulding price.

 

To have moderate plastic injection molding price

 

There are a few factory to offer injection molding cost.

Resin, generally you should consider your product function to choose the right resin. If you have no experience, you can tell your plastic molding factory product funcation and where you are going to use your product and how you are going to use your product.

Cavity, the more cavities, the higher mold and the lower unit price.

Color, Generally plastic molding factory offer the unit price based on different color, please let your molding factory know the quantities based on different color.

Certification of resin, you should let your molding manufacturer know the certification you need before order to prevent misunderstanding and argument.

Quantities, it is very simple to understand you need to let your moulding manufacturer know how many quantities you need to order each time.

Lead time,   this is also very important factor to affect unit price, specially on large volume plastic injection molding.

Secondary process, there are a few secondary process such as painting, printing, plate, laser cutting, package and assembly etc. process. Sometime you do not need. But anyhow you should know if your supplier is capable to offer this secondary service for you. For small volume injection molding production, it is not a reasonable solution to choose different factory to handle the secondary process by yourself due to there is higher manage cost and you probably need to under take the scrape rate.

In case it is a large project, you have many parts in one product. You can consider to collect all of the information in one BOM to offer to your plastic moulding factory. You can read page “BOM for complex plastic products inquiry to have competition”

In a word, you can try to understand more for above factor, and offer the same specification to all of the plastic injection moulding manufacturer. Then it is easier to choose the right moulding manufacturer. Then you have less argument with moulding factory.

Ultimate strategy for clear plastic molding

Ultimate strategy for clear plastic molding

To make high quality and afford price clear plastic molding products, you should give importance on both injection mold and plastic molding.  We will talk about to control plastic mold quality first, then we will talk about the injection molding clear parts.

Ultimate strategy for clear plastic moldingNo. 1 Choose right mold steel for clear plastic molding mould.

As you need to reach mirror polishing on cavity and core of injection mold for clear plastic parts. You have to choose high quality stainless steel for core and cavity. Based on different request for the polishing, you have different choice for the mold steel, then you have affordable price.

To choose your steel for core and cavity based on the polishing request. If you need above SPI A3 polishing, you have choose ASSAB S136  or NAK80 steel. At the same time, if the mold life or production capcity is more than 300000shots, you have to consider ASSAB S136 through hard steel.  If you need the polishing is around SPI A3 or lower than this, then you can choose FINKL 420 or China LKM 420 steel. Anyhow if the mold life is less then 300000 shot, you can choose prehard LKM 420 steel too.

NO. 2  Choose right injection mold factory to make the mold for clear plastic molding.

The plastic mold manufacturer should have experience for injection mold manufacturing for clear plastic product. On purchasing process, you need to have your mold factory to show you study case for clear plastic mold manufacturing. The best practise to have reference customer to prove it.  On the polishing process, it is very important to control the polishing method. In China most of mold maker is outsourcing for mirror polishing. There is professional mold polishing shot to finish the mirror polishing processs.

No. 3. Have the right draft angle for clear plastic product

If there is not enough draft angle for clear product, then it is easier to have scratch during clear plastic product injection molding.  If this is happen, you have to have mirror polishing again, if it is not solved. Then you have to chane your product design with big draft, it is terrible. So during design for manufacture process, your injection mold maker should have enough experience to carry out which draft should be suitable.

No. 4. Have less ribs as possible on the design if you need mirror polishing.

It is diffcult to polish the plastic ribs due to it small gap for polishing operators. It is diffcult to work. Please try to optimize your plastic product design as possible to reduce the ribs. Also for the clear plasit product, you also need to consider to have insert for the thin rib, then there is venting for the ribs, then it is easier to have the resin to fill into the gap to form ribs.

No. 5 Choose right plastic injection machine.

Lots of China injection programmer do not know the injection screws affect the injection result. For clear plastic parts, generally it is PC or PCTG resin. There is PS, SAN and PMMA etc. Generally smaller injection screw is easier to have good result. Nowdays, the injection machines guys will suggest right injection machine to shot different resin and product.

For thin wall and thick wall clear plastic molding, it is different to choose right injection machine. For thin wall clear plastic molding, you should consider high speed injection machine, generally in Japanese injection machine, it is electronic injection machine. For thick wall clear plastic molding, you can choose hydraulic injection machine, but you need to choose higher servo motor with smaller injection screw, then it is easy to shot thick wall clear plastic molding parts. In SEASKYTOOLING, we customize both kinds of injection machine to shot thin wall clear plastic parts and thick wall plastic molding parts.

No. 6 To get high quality clear plastic molding parts.

For common clear plastic molding parts, you can produce in generall injection plant. But for high quality clear plastic parts such as lens and light guide, you have to injection molding clear parts in clean room. SEASKYTOOLING have ISO 8 clean room for clear plastic molding.

Silicone rubber parts manufacturing solution with compression molding

Custom silicone parts manufacturer

Compression molding process is one of reasonable solution to manufacture silicone rubber parts with low mold cost and reasonable unit price. It is commonly to make multi-cavity steel mold to have compression molding production to make silicone rubber products such as silicone gasket, silicone tubes, silicone covers, silicone cases and silicone case etc.

Normally we call compression mold to make the silicone rubber parts as silicone mold. But some of peoples also call the silicone rubber mold to do the plastic casting prototype silicone mold as well, but it is different process.

Silicone rubber parts prototype manufacturing

It is the best solution to make the silicone rubber parts with single cavity silicone compression mold. We can have the reasonable cost on the mold making and silicone prototype. Also the silicone prototype is the same qualify and surface finishing as the production one. This process is cheaper than the rubber plastic casting and 3D printing process to make the silicone rubber prototype.

By using above process, we can also have the secondary manufacturing process such as silk-screen printing, painting ,PU finishing, UV finishing and etching etc.

Tips for Silicone rubber parts quotation from you China rubber parts manufacturer

Custom silicone parts manufacturing

 What kind of information you should offer to your China silicone rubber product manufacturer for quotation?

Silicone molded part drawing in 2D and 3D 

Normally all of the China manufacturer can read the 2D drawing in PDF, JPG, DWG, DXF and BMP format and 3D drawing in IGES, X_T and STEP.

If you have no 2D drawing, you had better to specify the accurate dimension on your document or email. If you have no 3D drawing and just have 2D drawing, you had better to specify the estimated part weight for you China molding manufacturer.

Quantities for the silicone rubber product manufacturing

You had better to offer the quantities based how many piece you should order each time, normally China mold supplier offer the cost based on the order quantities each time. You can also offer the estimated your plastic rubber part estimated life such as how many pieces you need to order in the next five years or ten years.

If it is possible, please specify the the colors for quantities of each order

Silicone keypad manufacturer

Normally this will not affect the price in SEASKYTOOLING, but the color is changed very frequently for very small quantities, there should be additional cost probably. But during your communication with your China silicone parts manufacturer, you had better to specify this to prevent the misunderstanding and argument during your purchase and cooperation.

Have your China silicone product manufacturer to specify the lead time for silicone mold making and silicone product manufacture

This is very useful for you to arrange your production, you can also let your China silicone product manufacturer know your production schedule.

Specify the shore hardness for your silicone rubber part

As not all kinds of hardness is suitable for the silicone rubber compression molding, normally 50-80 shore should be the best hardness for your China rubber compression molding supplier to handle. For the other kinds of hardness, you had better to check with your rubber supplier to prevent the misunderstanding after your order.  In SEASKYTOOLING, we checked this out with each inquiry and tell you what we can do. I am not talking about the silicone hardness without 50-80 shore is not possible to make, it have to check for different kind of silicone rubber parts.
