1.What is the medical parts?

Answer: Adapting to the development of medical technology, the medical plastic parts industry can develop rapidly. At present, there are thousands of plastic parts for medical use all over the world, and the technology of the products is getting higher and higher.

Meanwhile, the medical plastic materials are also put forward higher requirements; In general, the plastic parts used for disease diagnosis, treatment, monitoring, health care, and rehabilitation are called medical plastic parts.

Nowadays, medical parts are widely used in hospitals, laboratories, research institutes, and so on.

2.What is the application of medical parts?

Medical parts are widely used in hospitals, laboratories, schools, and research institutes.
Common medical plastic products include:

  • test tubes and other containers
  • Auto-injectors, Syringe Syringes
  • Housing for medical and laboratory equipment
  • Surgical Equipment and Parts
  • Drug Delivery Equipment and Components
  • Plastic Implants
  • Pipetting Instruments
  • Laboratory Consumables

 

3.What is the material of medical parts?

(1)PVC, Polyvinylchloride.
Pure PVC is a random, hard, and brittle material that is rarely used. Depending on the application, different additives can be added to give PVC parts different physical and mechanical properties. By adding the right amount of plasticizer to the PVC resin, a wide range of hard, soft, and transparent products can be made.
(2)PE, Polyethylene. PE has a high impact strength, low friction, stress cracking resistance, and good energy absorption properties.
(3)PP, polypropylene
PP is a thermoplastic with excellent performance. It has the advantages of low specific gravity, non-toxic, easy processing, impact resistance, and flexural resistance.
(4)PS, Polystyrene. PS is mainly characterized by lightweight, transparency, and good molding processability.
(5)ABS, Acrylonitrile Butadiene Styrene copolymers
ABS is rigid, hard, impact and chemical resistant, resistant to radiation, and resistant to ethylene oxide sterilization.
(6)PC, Polycarbonate
Typical properties of PC are toughness, strength, rigidity, and heat resistant steam sterilization.
(7)PTFE (Polytetrafluoroethylene)
PTFE has the lowest coefficient of friction of any plastic and is biocompatible.

4. What is the material property of medical parts?

The basic requirement for medical plastics is chemical stability and biosafety, due to contact with drugs or with the human body. the constituents of the plastic material cannot precipitate into the medication or the human body and do not cause toxicity or damage to tissues or organs. Because each material has unique properties that determine how the product will perform in an application, choosing the right plastic material for your medical part is critical.
(1) Have good tensile, flexural, compressive, and impact resistance properties and can be used alone as a structural material.
(2) Chemical and heat resistance. Chemical resistance and heat resistance are two key considerations when selecting medical grade plastic materials, especially if your medical product must be able to withstand autoclaves and sterilization methods.
(3) Strength and corrosion resistance. If the medical product will be exposed to radiation, then the plastic material chosen needs to be able to withstand the operating environment.
(4) Low coefficient of friction and good biocompatibility, especially in the medical insert molding, as well as other plastic products that are intended for use in the human body.
Kemal has rich experience to help and ensure that you are using the right plastic material for your medical product. We will consider the performance of your product and provide you with expert advice to ensure that the final product meets your requirements.

5.What is the common steel for medical molds?

We use high-strength mold materials for medical mold base, including 420H, P20, etc.;
for the main part of medical molds, including cores, cavities, and related inserts, we use high-grade plastic mold steel, including 1.2083, 1.2344, 1.2316, etc. And so on; and let the professional heat treatment company heat treat the main part of the medical mold, the hardness of the material is generally more than HRC48-52.

6.What is the key point to design medical molds?

(1) Choose hot runners for transparent products to reduce traces of merging.
(2) When using a cold runner, soft PVC should be used to shorten the runner size as much as possible.
(3) Due to the small size and large batch size of medical products, automatic unloading, and gating cut should be used to ensure production efficiency and quality.
(4) Transparent tubular parts, in the design should pay attention to the location of the gate feed and the dynamic model Z fixed the way, to avoid the gate position and the core of the incorrect choice of fixed methods, resulting in filling uneven during injection molding, resulting in inelastic deformation of the core, the product will be an uneven and short shot.
(5) Tube shaped products should pay attention to the appropriate venting method to avoid molding difficulties due to air trapping.
(6) Cooling system should adopt multiple separate cooling channels to reasonably control the temperature of the cavity and core to avoid product deformation.

7.What is the key point to produce medical parts?

(1) The injection molding shop should be fully enclosed, with high power air conditioners installed to ensure constant temperature and clean air in the workshop.
(2) The use of mold release agent and rust remover is strictly prohibited during the injection molding to ensure that the medical parts are not contaminated.
(3) The melting temperature should be strictly controlled during the production process to avoid harmful gases due to high material temperature and long stay in the barrel to decompose raw materials.
(4) Clean the screw and barrel immediately when the machine is stopped to avoid any damage to the screw caused by residual raw materials.
(5) Strictly follow the IS0 9000 quality management system to ensure that no problems occur in the production process.

 

8.What are the defects issues of medical parts?

Cracking, Sink Marks, Surface Ripple, Surface Delamination, Weld Lines, Short Shot, Warping, Burn Marks, Jetting, Flash, Bubbles, Shrinkage, Warpage, Delamination, Peeling, etc.

9.What is the difference between medical molds with normal molds?

(1) The material selection requirement of the medical mold is very strict because the medical mold is in the cleanroom to complete the injection molding work, first of all, the mold material needs to be stainless steel class materials, and need to do matching surface treatment, such as vacuum heat treatment, PVD coating, laser heat treatment, etc…
(2) Plastic materials for medical parts often have medical grade PP, PVC, ABS, PSU, POM, PA, etc., there are high-strength, corrosive, wear-resistance and high transparency, etc., so that the requirements of the injection mold is relatively high, the commonly used mold steel selection of imported S136, 2316, S136H, NAK80 … and so on, to meet the high corrosion resistance, high polishability.
(3) Medical mold structure design also has a lot of difference, many medical products are transparent color, the product as far as possible to choose hot runner, to reduce the dissolution of traces.
(4) The manufacturing precision of medical mold is higher, medical-related injection molding products are definitely absolutely not allowed to have any flash, which requires extremely high processing accuracy of the mold core, part of the core processing accuracy requirements of less than 0.005mm.
(5) The injection molding environment of medical molds is relatively harsh and needs to be carried out in a cleanroom to ensure that the products are not contaminated.
In general, the medical mold is not much different from the normal mold in structure, mainly in the control of processing technology and processing precision.

(2) Increase the barrel and nozzle temperature as well as the mold temperature to increase the flowability;
(3) Increase the feeding volume of the molding machine;
(4) Select an injection machine with a higher injection volume;
(5) The runners and gates are too small, increase the gate size appropriately;
(6) Increase the injection pressure;
(7) Increase the injection speed;
(8) Improve the mold design and add venting properly.

12.How to improve medical mold quality?

(1) First of all, the design of the medical mold should choose the best structural solution, the designer should consider the technical requirements and its structure must comply with the manufacturability and feasibility of the mold.
(2) The choice of material for the medical mold must meet the customer’s requirements for product quality and also take into account the cost of the material and the fact that the mold has sufficient strength and rigidity.
(3) The processing method and machining accuracy in the manufacturing process of the medical mold will also affect the lifespan of the mold. In order to ensure that the mold has good precision, in the manufacturing process, we should first choose a high-precision processing method, followed by the main components of the mold surface to strengthen, improve wear resistance, so as to better improve the mold quality.
(4) Correct use and regular maintenance of medical molds can prevent problems that may occur during production and improve the lifespan of the molds. It is also a major factor in improving mold quality.

13.How to choose injection machines for medical molds?

For medical products without special cleanliness requirements, such as fitness and equipment products, general injection molding machines can be applied.

For medical products that need to be produced in a cleanroom environment, injection molding machines, and peripheral equipment that meet cleanroom standards should be used. For example, for the production of injection syringes, because of the high requirements for appearance and size, you should choose a machine with precise control and suitable for multi-cavity thin shell molding; If manufacturing medical electronics, then in addition to the stability of the machine, you should also consider whether the auxiliary equipment can meet the requirements accurately and efficiently.

14.How to check the medical molds before putting them on the injection machine?

(1) Scrub the dust, oil, and rust on the appearance of the medical mold and remove the dirt on its appearance before putting it on the injection molding machine.
(2) Use an air gun or rag, decontaminant, or alcohol (alcohol for mirror medical mold) to clean up the oil and dirt on the medical mold surface.
(3) Check the cooling water channel of the medical mold for foreign objects and make sure the cooling water is smooth.
(4) Check whether the arc in the sprue sleeve of medical mold is damaged and whether there is a residual foreign matter if there is a need to clean up.
(5) Moving parts: such as ejector pin, taut spring, hydraulic cylinder, slider, whether there is rust, bending, fracture, activity necessary whether smooth.

 

15.How to maintain the medical molds after production?

(1) Test each part of the medical mold for damage.
(2) Tidy up the oil on the parting surface and the debris left in the mold cavity, and spray the anti-rust oil.
(3) Blow-dry the water left on the cooling water channel.
Please noted that:
It is necessary to wear labor protection when maintaining medical molds, and it is necessary to operate with a crane for overweight objects, and it is strictly forbidden to lift medical molds directly by hand to prevent injury to the limbs.
It is necessary to prevent the rust of medical molds, after the maintenance of medical molds, special attention should be paid to the anti-rust action of medical molds, and it is necessary to blow dry the residual water inside the waterway with an air gun.
Adding too much smooth oil does not bring a better smooth effect, the right amount is enough.
When the medical mold is finished, we should pay attention to the number and direction of the inserts and other parts not to be installed in the wrong way, check whether the screws are completely used up, and lock the screws in the diagonal direction when installing them.

16.How do I choose a partner for medical injection molding?
