custom plastic injection mold
Custom plastic injection molding is a process through which liquid plastic material is formed into required product shapes by injecting the same under high pressure into the metal moulds.
Different products require customized moulds that can produce a unique look and finish. Customized tools play a vital role in providing various products today like Automobiles, consumer goods, telecommunication equipment, and appliances etc. These all essentially need custom made molds for their successful production.
The process of custom plastic injection moulding takes place according to the below steps:
I. Mould design
Firstly the mould designer formulates the design of custom plastic injection molds on CAD (Computer-Aided Design) software. After designing the whole part, molds are split into individual pieces for easy assembly during the production phase. Once all components are created, they are analyzed for their strengths and weaknesses using finite element analysis software.
Custom molded tools or dies are fabricated from steel or aluminum alloy to meet specific requirements like low cost, minimum wall thickness, material & dimensional accuracy, etc. The tooling process includes machining, metal removal processes like drilling and milling, etc., heat-treating operation to increase wear resistance properties of steel tools, and other secondary techniques like coating tools with anti-corrosion material to improve life. The metal tools are mounted on a hydraulic press for injecting plastic under high pressure into the cavity. Several die sets are required to produce large parts, leading to higher production costs.
III. Injection molding
The injection molding process involves injecting molten plastic into the die cavities at very high pressure and temperature. Moulds remain closed until the product has cooled down completely, after which they open up to release the part from the tool.
The injection moulded parts are allowed to cool down before being removed from the moulds so that their shapes and dimensions remain accurate throughout the entire process cycle.
A custom-molded part is formed by injecting molten plastic into the metal molds under high pressure. The custom plastic molding cost depends on its complexity, including some parts, parting lines, draft angles, etc. One additional factor that could increase the price is special features like inserts, secondary operations, etc.
Custom parts can be made on an injection molding machine using the below steps:
I. File preparation (CAD files)
CAD file contains design data of part geometry and material thickness, draft angles, etc. It is required for converting into a tool path that controls the action of the hydraulic ram system during the production phase. The moulder prepares a tool path that includes X-Y motions of moving ram and its Z motions to adjust shot volume. Some CAD software has the functionality to prepare complete process flow charts in a diagrammatic form, thereby making it easier for operators to understand how moulds will work while producing custom molded parts.
II. Preparation of injection molds
Injection Molding machines are usually equipped with two mold halves. These are mounted on a clamping ring with specific clearances to reduce cycle time and achieve the required shot volume. Openings for ejector pins & vents are cut in these molds according to the requirements of parts so that they can be quickly ejected from the tool during the production phase.
III. Injection phase
Molten plastic is injected into molten steel or aluminum injection moulds under high pressure and temperature by a hydraulic ram system using process oil as a cooling medium after melting material pellets. It flows through passages formed in the mold to fill internal cavities that define the shape and dimensions of each part accurately without causing any defects like sink marks or warping etc. The main parameters that affect nozzle flow rate and shot size include injection pressure and screw rotation speed.
IV. Cooling & ejecting phase
After completing the entire cycle, the plastic part is allowed to cool down inside the mold cavity. Its shape and dimensions remain accurate before it is ejected from the tool by using ejector pins. The machine opens up after this process to release parts one by one immediately after the cooling phase for secondary operations like finishing, inspection etc.
The lead time for delivering custom moulded parts depends on the number of produced features.

Applications of custom plastic injection molding
Custom injection molded parts are used in various applications like automotive, electrical appliance industry, medical and consumer goods, etc. these components play an essential role in making production lines more efficient and cost-effective. Their properties like durability, abrasion resistance, and compatibility with lubricants make them widely preferable by end-users for designing high-performance products that offer a better value proposition to customers.
Custom injection molded parts can be designed per the customer’s specific requirements regarding size, shape, functionality, etc. This feature makes them highly preferable by end-users for creating high-performance products that offer a better value proposition to customers.
- They are made of high-quality materials that ensure durability and wear resistance even in the worst conditions like temperature variations.
- The minimum wall thicknesses of these parts help save space efficiently during the production phase.
- Custom molded parts are easy to design and use in production lines.
- Customer requirements related to colour, glossiness, hand feel & texture can be easily achieved using a custom injection molding process.
Plastic mould design is considered during the initial stage of product development to deliver custom moulded parts with accurate dimensions and shape.
Designing injection molds is a complex process that requires high expertise & special training in this field. Manufacturers should always outsource plastic mold design projects to reliable partners like Go4mould. The latter is known for offering end-to-end assistance related to different stages involved in the production cycle.
Plastic injection molds should be adequately lubricated before the first shot to avoid sticking issues. Additional care is required for the machine’s smooth operation because it involves high pressure and temperature for melting plastic pellets inside the barrel.
Proper maintenance & testing procedures should always be followed so that the production line remains free from any defects caused due to malfunctioning parts etc.
Plastic injection molding can cut down overall manufacturing costs for custom molded parts because it offers high volume production at the lowest possible unit price.
We have an in-house R&D team that can suggest innovative methods to reduce costs without compromising the quality of plastic components. For example, using new technologies like thin wall moulds & innovative tooling, etc., reduces overall development time and offers quick ROI (return of investment) for various projects across different industry verticals.
Metal stamping vs. plastic injection molding
Metal stamping is an economical option to produce small batches of metal components. It does not offer high dimensional accuracy and surface finish, so they are never preferred for designing parts with critical requirements related to functionality, appearance & structure, etc.
On the other hand, plastic injection moulding allows manufacturing custom moulded components in a wide range of materials, including engineering plastics, polymers & metals with precise dimensions and superior strength & rigidity properties, etc.
A wide range of materials is available for custom molded parts manufacturing using the injection molding process. The details are as follows:
It is a versatile polymer that offers good dimensional stability and machinability. These plastic materials are available in different grades depending upon their usage, including commercial, industrial & engineering applications. The maximum shrinkage rate for this material is 0.3%, so it is best suited to design thin-walled parts with complex internal structures.
They offer high formability and dimensional stability, but they become brittle at low temperatures due to the high crystallinity level of these plastics. However, this problem can be resolved by using additives like glass fiber, such as nylon 6/6 & nylon 11/12, which possess high stiffness & heat deflection temperature making them suitable for designing parts that need high impact resistance properties.
They are known for offering excellent wear & abrasion resistance and an extremely low friction coefficient. These materials are popularly used in custom plastic injection molding applications that involve sliding & rolling parts like gears, rollers & bearings, etc.
It is a versatile engineering thermoplastic material with better mechanical strength, dimensional stability, and heat resistance properties. The primary application areas include designing transparent components used across automotive, consumer electronics, medical & military sub-segments.
PBT is another commonly used engineering polymer that offers better mechanical properties at higher temperatures than other common engineering plastics like nylon, PC, etc. Using hot runner technology, PBT can be quickly processed in high-performance injection molding machines.
POM is commonly used to produce smaller metal replacement parts. They are combined with steel or iron components in the final stage of the manufacturing process to increase its wear resistance properties etc.
ABS plastic injection moulding is a process that injects molten ABS plastic into a pre cut mold.
