حقن صب وتصنيع الأجزاء البلاستيكية الطبية

الأجزاء البلاستيكية الطبية هي منتجات بلاستيكية تستخدم خصيصًا في الصناعة الطبية. يمكن أن تكون هذه الأجزاء مكونات للأجهزة الطبية, المساكن, موصلات الأجهزة الطبية, الأجزاء الهيكلية, الموصلات الطبية والأدوات الجراحية, من بين أمور أخرى. يتم تصنيعها بشكل رئيسي من خلال عمليات القولبة بالحقن, والتي تخضع لمعايير نظام صارمة لتلبية متطلبات الصناعة الطبية. These parts play a key role in the field of medical devices for diagnosing, treating and monitoring patients, and therefore require very high quality.

1. What is injection molding?

Injection molding is a widely used process for manufacturing plastic products. The basic principle is that molten plastic material is injected into a mold and subsequently solidified upon cooling. This results in the production of plastic parts and products of various complex shapes and sizes, which are widely used in a number of industries. It is an important processing method for medical parts.

2. What are the common injection molding processes?

صب الحقن:

In injection molding, plastic pellets or granules are melted and injected into a closed mold. It is then cooled and cured in the mold, resulting in the desired plastic part or product.

Insert Injection Molding:

This refers to the injection of resin into a mold after filling it with pre-prepared inserts of dissimilar materials. The molten material and inserts are joined and cured to make an integrated product molding process.

Two-color injection molding:

It allows the combination of two different colors of plastic in one mold. This process results in more aesthetically pleasing medical parts.

Microfoam Injection Molding:

An advanced injection molding process that uses gases dissolved in the plastic and then released during the injection molding process to create tiny bubbles or pores. These tiny bubbles improve the density, strength, texture, weight and material usage of the material to meet different product performance and cost requirements.

Nano injection molding:

Through nanotechnology, the surface of metal is nano-treated. The plastic is then directly injection molded onto the metal surface, thus realizing the one-piece molding of metal and plastic.

Blow Molding:

Blow molding is a commonly used plastic processing process by heating and extruding plastic pellets into shape. The plastic pellets are then blown and inflated by air pressure into a shape inside a mold to create hollow plastic products, often used to process medical containers and pipes.

Extrusion Molding:

Extrusion molding is an injection molding process widely used to manufacture plastic products. By extruding heated plastic pellets through the rotation of an extruder screw, the pellets are then formed into the desired shape.

3. Which medical plastic parts are suitable for injection molding?

• Medical device housings and components: such as housings, panels, buttons, connectors and so on.
• Syringe and infusion parts: such as syringe plungers, syringe cartridges, infusion connectors and valves.
• Respiratory Devices: Medical devices such as respirators and oxygen masks require plastic parts for sealing and hygiene requirements.
• Medical containers: plastic containers, bottles, drug packaging for medical purposes, إلخ.
• Dental equipment: Dental equipment requires various plastic parts, such as dental mold cups, dental impressions, braces, إلخ.
• Surgical tools: Handles, grips, and other components of surgical tools and instruments are also often processed using injection molding.

4.How to choose a medical plastic parts factory?

Choosing a medical parts injection molding factory is a critical decision because the medical field has very high requirements for quality, hygiene and compliance.
The medical industry should choose a factory with ISO13485 certifications to ensure that the product meets the customer’s regulatory requirements and standards, and these certifications also show that the factory meets the standards of the medical industry.
It is also important to choose a factory with extensive experience and manufacturing know-how, especially in injection molding of medical parts. The factory should understand the special needs of the medical industry and can support the customer’s project and maintain communication.
