Plastic mold manufacturer in China

by

When you develop a new plastic model,you need find a reliable plastic mold manufactur to make the mold
Since the company size,location and history are different,they will quote you different price.at the moment lots of trading company protend to be a plastic mold manufacturer to dealing with you,they will take at least 30% profit from you and do nothing, Just think about it,if your competitor find a true plastic mold manufacturer but you find the trading company to develop same project,they will have 30% price advantage compare to you.do you think if you have any chance to win the market.

How to find a reliable plastic mold manufacturer?

I think it’s better to spend some time to get to know one or several plastic mold manufacturer really well. Visiting them is best idea once you get a good feeling about it (after discussions about the mold engineering or making a small test mold), when you have a good relationship with an plastic mold manufacturer and you will know how they think about the technologies and use the same language to discuss mold engineering, more effective. You can move on your project very fast.That’s where the profit is along the life of the project. Steel is steel and CNC machines are the same for every shops. In the end it counts on the people who work with you and if someone does a value stream analysis of a project, the mold quality will be different.

Visit the plastic mold plant and check the facility available with them, ask about his existing customers and main marketing ,Check the molds which are on construction in the shop, see the project management system, look at the sample components they made in the past. All this will give you an idea on the capability and the quality levels of plastic mold manufacturer
Then check which is your most concern like, lead time of mold building, finish of the samples, dimensional criticality, quality of steel, after sales service like modification of mold based on the change in design change during the mold life, durability of the product..

The most important is:find many plastic mold manufacturers for price and quality check,choose the best and proper one as your business partner

Low Volume Injection Molding production company

by

When you design a new product, you want to trial them in the market before you invest lots of money to make big production, Now the problem come out,the big factory or famous companyhave the big amount for MOQ,but you worry about the quality with small shop, Now ECO molding focus on providing this service of Low Volume injection molding afte optimize our management system and marketing.
Nowadays, it is important for a company to get new models into the market quickly, in most of the cases, it could be just a market-testing product with 10,000 units’ volume or even less. But the plastic parts still need to be customized by plastic injection mold to achieve the specified tolerance, finish, function. Traditionally, a hardened steel mold would requires a big amount investment before you get a simple piece, and it usually take 8-12 weeks to finsh the mold, it will lose the precious time to occupy the market.
Most important is the cost,Low volume mold will be much cheaper than harden up mold,Spending the same money,you can lauch more projects, it will help you enhance the chance to succeed. if one project failed, you still have money to develop next project.

low volume injection molding requires a mold first, start with  mold design, and then CNC, EDM, wire cut, polish etc. all processing used by making a hardened steel mold are adopted to make a mold for low volume production. Low volume mold sometimes refer to rapid tooling or prototype tooling. To achieve cost advantage, the mold use lower grade steel(mostly local steel) or aluminum, which don’t have to be withstand hundreds of thousands times of injection press as production mold. Molds made by pre-hardened steel or aluminum are capable of 10,000 to 300,000 molding cycles, this is enough for the needs of most project which didn’t make big success in the market. The lead time of building mold is shortened massively because the steel don’t have to be hardened up after rough CNC machining, the workability of soft steel is also better than hardened steel, which make the processing is easier and faster.but the finish and quality is the same level as harden up steel mold

The advantage of low volume mold

  • Save lots of money but never compromise with quality
  • Short lead-time
  • Easy to modify the tooling
  • Reduce the risk of new project

Injection Molding Process

by

Injection molding is the most commonly used manufacturing process for the fabrication of plastic pieces. A wide variety of products are manufactured using injection molding, which varies greatly in their size, complexity, and application. The injection molding process requires the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part. The steps in this process are described in greater detail in the next section.

injection molding process machines

Plastic parts are used in a variety of products including home appliances, consumer electronics, power tools, and as automotive dashboards. Other common thin-walled products include different types of open containers, such as buckets. Injection molding is also used to produce several everyday items such as toothbrushes or small plastic toys. Many medical devices, including valves and syringes, are manufactured using injection molding as well.

the plastic parts have many advantages compare to metal parts, glass, wood.such as lightweight, cheaper price, and the cycle of production will be shorter the different hardness and chemical stability. and better insulation performance.

Injection Mold Tooling

by

As we know, if you want to produce a plastic product,you should make a injection mold tooling first.the mold is the key equipmemt for the shape.so let’s lear what the injection mold tooling is.

The injection molding process uses molds, typically made of steel or aluminum, as the custom tooling. The mold has many components, but can be split into two halves. Each half is attached inside the injection molding machine and the rear half is allowed to slide so that the mold can be opened and closed along the mold’s parting line. The two main components of the mold are the mold core and the mold cavity. When the mold is closed, the space between the mold core and the mold cavity forms the part cavity, that will be filled with molten plastic to create the desired part. Multiple-cavity molds are sometimes used, in which the two mold halves form several identical part cavities.

The mold core and mold cavity are each mounted to the mold base, which is then fixed to the platens inside the injection molding machine. The front half of the mold base includes a support plate, to which the mold cavity is attached, the sprue bushing, into which the material will flow from the nozzle, and a locating ring, in order to align the mold base with the nozzle. The rear half of the mold base includes the ejection system, to which the mold core is attached, and a support plate. When the clamping unit separates the mold halves, the ejector bar actuates the ejection system. The ejector bar pushes the ejector plate forward inside the ejector box, which in turn pushes the ejector pins into the molded part. The ejector pins push the solidified part out of the open mold cavity.
The mold life is different depends on the steel of inserts,if the inserts are made by pre-hard steel.the usual mold life is 300,000 shots.if the mold core and cavity inserts made by harden up steel,such as 1.2344,the mold life will reach 1,000,000 shots. The mold tooling is not cheaper because that the material(steel) is expensive,the process is very complicated and need rich experience staff.the price ranged from 1000-300,000USD

Rapid prototyping

by

Nowdays, the economy develop faster and faster, it create a more and more demand for new product. as we all know, if we need plastic product or a plastic spare part, we should make a mold, but the mold will cost very much and take a long time, if our design is not good or not accepted by market, we will lose a lots of money and waste much money in the molds, now we comes out a new solution-rapid prototyping.

Although the 3d Print is coming, but CNC machining still be use in majority of prototype,because the finish of 3d print parts is not good enough for business show even if they make the structure of product. Product designers and new product developers require machined metal and plastic prototypes in the same timeframe as other prototype components such as SLA models, sheet metal parts,  and metal castings. the Trade Show date is not moving, your internal project date has management visibility, and that your customer’s order is time dependent. If we fail to deliver your machined parts when you need them, your decision to use Rapid Machining comes into question and may very well impact your next raise or even your job. our employees average over 20 years manufacturing experience and we rely on seasoned machinists to stream-line part manufacturing and smooth out any bumps. The majority of our machinists can do any job in the shop including programming, setting up all machining centers, and even shipping parts. Why is this important? Because their critical knowledge gained through those years of experience ensure your parts get shipped on time and with a high quality level

If you need the rapid prototyping serive,maybe we are your wise choice.

A Injection Molding Technician’s Work Report

by

As we know, once the mold are uploaded to the injection molding machine, they should work till the order is done.but every day the mold need stop for shift,my present view is: inspect the mold very carefully, solve the problem occurs in injection machines, control the quality after maintenance. If we do three good, we can shorten the stop time within 50 minutes,it means 25 minutes one shift

Leadership also is thinking how to achieve this goal. If we do not really take the initiative to make real work done, all plan are nothing, fortunately,I really want to do this job well, it can be considered to prove our value, or something else, in short, this thing is a major event in my work next year.

This would be good that all the people are mobilized through the mold repair team.

1, good point inspection program.

2, set up inspection teams, primarily responsible for the completion of inspection program.

3, setting up the monitor to check the quality system.

4, good seating arrangements for the team’s work.

5, the problem of online off-line processing, especially long-term torment online maintenance staff.

6, perfect check of the operating instructions. For example: all spring ,check all the screws removed infrequently, all movement spare parts

In short, do practical work, reduce mold downtime, increase productivity
