3 Facts About Micro Molding 

 August 25, 2022

First Things First

Hospitals and clinics require a range of medical equipment. Some of that equipment is durable, while the others are disposable. Unlike other fields, the margin for error in the field of medicinal equipment is very low. Specific tools like syringes and injections need precision. Medical micro molding is the process that enables the production of particular tools required in surgeries and the general practice of medicine.


The standard process is more geared toward hundredths of an inch rather than single micron stack up tolerances. Micro-molded components frequently have thinner walls and tighter tolerances and are challenging to handle and package. Manufacturers can provide proper equipment to the industry with the correct combination of materials. It is essential to carefully consider all process inputs and the intended percentage of tolerance that they will include.

Fundamentals Of Micro Molding

  1. Dimension Of Articles To Be Molded

The process of micro molding is just like the name suggests. Molding is a common term, but micro is used as a prefix because of the nature of the space it works in. Usually, when producing items under one square inch of the area, the prefix of micro seems suitable. There is an underlying purpose of forging things that small instead of carving them out later. It is to reduce the number of steps in the process of production.


At the same time, it is beneficial to have precision. Another critical factor is that standardization should exist in manufacturing the products using the process. Since the same mold is reused again and again, the finished products also end up alike. Standardization is an essential element for maintaining the quality of tools to be used.

Often, the molding processes are used in the production of items other than injections only. Lego is a famous brand for children’s toys. The building blocks company has some of the most intricate details in its blocks. Initial versions of the blocks produced by the LEGO corporation were composed of wood. But later on, the business expanded to a large extent. The company was looking for a means to increase production to keep up with growing demand from customers.


Their answer was to spend money on a micro molding machine which made him transition to using plastic. It also made it possible for them to produce plenty of identical toy components. Initially, It was only capable of producing twelve blocks at a time. Injection molding technology ultimately advanced to the point where machines could handle higher production outputs in less time.

These machines for micro molding only offer a process. The process can be applied to a variety of things as demanded. Even in the case of Lego, the requirement was quite unique. Similarly, miniature plastic-based components sometimes have to be installed in cameras and recorders. Even the best ptz camera for broadcast requires small details. Producers can install them using the process of micro molding.

  1. Multiple Grades Of Material

A material’s hardness, often known as its Shore hardness, refers to how well it resists indentation. In order to determine a material’s precise hardness, it is either classed as type A or type D. It is also assigned a value between 0 and 100. Substances with different levels of hardness are used in the process of micro molding. It is based on the rigidity of the final product to be delivered.

The machine incorporates a massive range of elements that the device can use to give accurate levels of rigidity. If something is meant to be disposable, the rigidity is such that it can be disintegrated without incurring extra costs. The density of a substance affects its weight, with less dense substances weighing less and more dense substances weighing more.


Generally, syringes are lightweight. Most hand based tools are meant to be light, or else it becomes inconvenient for their users. Especially during surgeries, or medical procedures like vaccination drives, syringes have to be used all day long. If they are not under the standard weight, inaccuracy might be bred.

The capacity of a material to tolerate bending under stress is referred to as flexibility. While stiff substances are more likely to crack when bent, flexible materials are less inclined to do so. It is beneficial for specific equipment in the medical field that requires some amount of tension retention. The characteristics as mentioned earlier influence how the final product will function. However, it’s also crucial to consider the project’s financial limitations while selecting a material.



Typically, the micro molding allows tremendous control to the producer. The medicine industry greatly owes this revolutionary method. Doctors use surgical gloves whenever they are treating patients. It is a means for maintaining the standard level of hygiene. Occasionally, the oem latex surgical gloves have to be engineered in a certain way to suit the surgical procedure. There are tiny irregularities made on the gloves to enhance the grip.
