China is also accomplished in running engineered thermoplastics with melt temperatures ranging up to 750 degrees F with a wide variety of fillers, reinforcements, additives, and colorants.
Molds can be hand operated, semi automatic or fully automatic.
Hand operated molds require an operator to physically remove the mold from the press and disassemble it to remove the molded part. They are used for very small quantities (1 – 500 parts) or parts that have undercuts, threads or other complicated features.
Semi automatic molds are typically mounted in the press and require an operator only to perform a specific operation of the cycle (i.e., remove a core, place an insert, remove the part from an undercut).
Fully Automatic molds run with no operator. They may utilize a variety of mechanical devices to facilitate part removal such as mold sweeps, air blasts, spare pickers or robots. They may contain core pulls, cams to remove undercuts, multiple plates, hot runner or insulated runner systems, unscrewing devices or any number of devices and techniques to improve efficiency.

Injection Mold Equipment

Mold has been considered one of the most expensive methods to manufacture equipment including metals, glasses, elastomers and confections for the industrial application use. These days molding is a process that is very commonly used to meet the growing requirement of various injection mold equipment that is being used in multi-applications to create many things such as bottle caps, pocket combs, wire spools, parts of numerous musical instruments, chairs and tables etc. The one and only disadvantage of this overall process is the demand of heavy cost equipment investment, potentially high running costs, and the need to design moldable parts.

There are very few injection mold companies, which are major putting collective efforts to manufacture high end metallic parts by utilizing injection molding machines consist of a material hopper, an injection ram or screw-type plunger, and a heating unit. These are called presses in which the components are designed or carved. It will be rated by tonnage, which expresses the amount of clamping force that the machine can exert. This force keeps the mold closed during the injection process. It’s an emerging mold making company which is promoting the use of most recent injection molding technology and systems, which can be integrated seamlessly into the machines. To grow with the industry norms and making products of high utility to create an image around the world with outstanding reliability, universal application and individually adaptable high-end technical solutions.

With repeatedly setting benchmarks by initiating precision in manufacturing systems and solutions for the specialized industry usage in mold making, most of the companies are rendering their key focus on producing extremely innovative quality parts registering superior design capabilities for various purposes. Injection moulding of plastic is also becoming integral with time to help various industries grow and materials such as polystyrene, nylon, polypropylene and polythene, which can be used in a process called injection moulding. These are thermoplastics – this means when they are heated and then pressured in a mould they can be formed into different shapes. For the companies which produce, quality management system is very crucial to produce standard and precise products. Essentially injection molding is used for create a variety of parts, like plastic milk cartons, containers, bottle caps, automotive dashboards, pocket combs, and most other plastic products available today. Injection molding is the most common method of part manufacture. Injection molding is a cyclic process that is an on-going activity for manufacturing parts for a number of purposes.

How To Buy High Quality Plastic Injection Mold

How To Buy High Quality Plastic Injection Mold

There are plenty of injection Mold Company in China, especially gathered in Guangdong province and Zhejiang province. Then how to customize good quality plastic injection mold? How to choose most suitable mold company?

Mold flow analysis

Before detail mold design, should have mold flow analysis of plastic part. By analyzing material flow direction and path route, check whether injection gate reasonable or not, or there is any flowing imbalance or other problems.

Professional Plastic mold design

Mold design is the basic, also it is the first important item for mold manufacturing. It must be reasonable, based on exact plastic part’s requirement, then to have the most appropriate design. For example, PVC injection molding, if plastic part small, better to use valve gate system or submarine gate. For large PVC part with thick wall, then better to use fan-shaped gate type.

Mold tooling

Good quality injection mold related to precision mold tooling. For example, medical syringe barrel mold, it has strictly requirement of mold core part’s verticality, almost there is no demolding angle, as require sealing the best between barrel and gasket. Here best to use Japanese brand Sodick precision wire cutting machine, mold dimension can be controlled within 0.005mm. Additional, Fidia three axis high speed CNC machine from Italy, Agie Charmilles EDM machine from Switzerland, are most suitable for tooling high precision plastic mold for medical plastic parts, packaging parts and automotive parts. When you hesitate to choose which mold company, to check their tooling equipments first.

Mold installation

After all above items smooth finished, then comes to labor works. Mold assembling and installation should be done carefully, workers should pay attention to this part, make sure every spare part has been assembled and in most suited location without any damage. Also make sure under safety condition.

Mold adjusting and testing

If injection mold have any problem, then it can be directly reflected on plastic parts. Mold testing is important, as custom plastic mold company and client will have fully understand, then know how to fix the mold or next. So at first, all related auxiliary equipments should be well installed, like air blow system, water cooling system, etc. Check its reliability, then add plastic material to test the mold. At the same time, injection molding condition should be suitable.

How to make plastic injection mold

How to make plastic injection mold

The process of making a plastic injection mould consist of determining what should be the size of
the mold, designing the mold, ordering required materials for the design, creating a rough shape, heating the mold, precision machining, wire cutting, polishing and fitting and trial of the mold.

Step 1: Determining the size of the plastic injection mold.

This process is not hard and does not require a lot of time. The end product, the plastic shape, determines the size of the mold.

Step2: Designing the mold.

Computer CAD design is used to draw the design. First set a 2 dimension layout and make sure you have all the mold
design features marked such as the size of the mold, parting line, the layout of the cavities are all set. Note the information that will be needed such as the mechanical design and the accessories that will be used.

After the two dimension layout made is satisfying and all information is noted make a
detailed 3D design. This will require programming skills to create. It may take some time to complete the designing with regards to the complexity of the mold.After the first 3D design is made it is necessary to assess any need for adjustments and the flow of the mold.

Step 3: Ordering the required molding material

After your design drawing is completed its time to order the required material. This may include desire steel, cutting tools and plastic part samples.

Step 4: Creating a rough shape of the plastic molds

Sizing of the steel then milling and drilling comprises this step. Make the desired steel shape and drill the holes needed as per the design in a rough work machine. Leave polishing and smoothing for later.

Step 5: Heating the mold

Heating is done as a form of treatment after creating the rough shape to harden and balance the created steel shape. Not every type of steel may need heating, an example, the P20.

Step 6: Precision machining.

Precision machining works slower due to the hardened steel properties but will get the design dimension created as per the design drawing.

Step 7: Wire cutting and EDM

Wire cutting is a process where special holes are made in to the design. These holes include pin holes for the ejector, for the lifters and the inserters. EDM helps work on narrow spaces which cannot be machined easily or where the space is too small for the cutting tool to get in.

Step 8: Polishing and fitting
polishing and fitting the created mold in to the mold maker machine follows.
The mold maker machine will collect all parts put into it and will follow the
design drawing to make the finished plastic mold. When the machine work is done further
polishing and engraving follows to complete the design.

Step 9: Trying the mold.

After the mold is created it will be good to try if it will work for the desired plastic shapes. The mode is installed in the plastic injection molding machine and injection parameters are set to work on the plastic samples acquired. If the mold is good enough for the job, well and good, the mold creation process is complete. You can now proceed to create the desired plastic products or sell the design to another company.

Injection Molding Process

Injection Molding Process

The thought of processing PEEK (polyetheretherketone) or other high-temp resins can send nervous tremors through many a molder’s body.  I know, as a molder who learned the craft on a steady diet of PP and PE closures with their low melt temperatures and cold a plastic molds, my first PEEK experience made me edgy to say the least.  But I’ve since come to realize that PEEK is just another thermoplastic resin and, like the others, can be molded safely and efficiently with just a few precautions.

PEEK is widely believed to be one of the highest performing thermoplastics on the market and its end properties more than justify any trials and tribulations you may encounter processing it. PEEK is a linear aromatic, semi-crystalline thermoplastic having excellent wear, chemical and hydrolysis resistance. It has very low flame/smoke toxicity and excellent electrical properties that preclude the need for additives in many cases.

PEEK processes at a high melt temperature nearing 720°F, and both the press barrel and controls must be capable of this. On many plastic molding machines the high heat software is an option and I recommend ceramic high-temp heat bands whenever possible. A special screw and barrel are generally not needed, but consider hard units if running filled PEEK resins. We typically use sliding ring non-return valves, GP or Eliminator™ tips and don’t recommend ball checks or shutoff nozzles.

A hot mold is the key to achieving crystallinity in PEEK parts. Purging PEEK allows you to see the color change from a translucent to a solid colored crystalline state. If the mold is too “cold” (i.e. not hot enough) the parts will have that discoloration or partial translucency, and the quality of the end product will be compromised. The mold, in most cases, must be between 350°F and 450°F. This is steel temperature and requires oil or cartridge heat to maintain this level. Complex parts may require better temperature control so oil would be the preferred option. We also recommend the use of thermocouples to verify and monitor the steel temperature.Plastic Mould & Plastic Molds

These plastic molds must be specifically designed to run high-temp materials with draft, finish, undercuts and steel types all factored in from the beginning. Insulator plates between press platen and mold clamp plates are a must. The preferred steel type would depend on whether or not the resin uses any abrasive fillers but should have a minimum hardness of 52-54 Rc.

The resin also must be very dry to process well and achieve the desired end properties. This means that the resin must be at 0.02% moisture or below. We typically recommend drying the resin at 300°F for at least 3 hours. We also suggest the use of a moisture analyzer to assure dryness.

PEEK can be quite costly, but you should be able to use 30% dry first-pass regrind with unfilled PEEK and 10% with filled PEEK.

Safety should be a primary consideration when molding PEEK, both for purging and while working with the mold. Wear safety glasses and/or a face shield, Kevlar or Kevlar/stainless steel sleeves, and heavy cotton cloves when purging and reaching into the mold.

When preparing for your PEEK experience, research it well with your resin supplier. The above information is based on my experience, but it should used as a reference only. Also, make sure you don’t neglect recognized scientific principles when working with any thermoplastic material. With a bit of common molding sense, your PEEK experience can and should be a rewarding one. click here to get more detail about plastic molds and plastic molding technology.
