injection molding services overmolding

Overmolding

Overmolding starts by molding a single material, typically the harder material, in a mold and then ejecting it and cleaning off the gates. This part is known as the substrate and is then placed into a second mold to be molded over with a second material known as the overmold.
2K two shot Molding

2K (two-shot) Molding

2K Molding is done in a single injection mold machine with 2 or more injection units and with a tool that has 2 cavities that rotate between molding cycles to allow for multiple material parts.
injection molding services insert molding

Insert Molding

Molding together plastic over a preplaced plastic or metal insert. Insert molding is done by placing inserts or some other material into a mold before the molding cycle. When the plastic is filled into the cavity, the insert is encapsulated securely within the final part.
Gas Assist Molding

Gas Assist Molding

Gas Assist Injection Molding is a molding process that uses pressurized gas like Nitrogen to hollow out thick sections of a plastic part during injection. The gas pushes molten plastic against the mold walls, reducing material usage, minimizing sink marks, and improving structural integrity.
micro molding

Micro-Molding

Micro-molding is an injection molding process used to manufacture extremely small and precise plastic components, often with intricate geometries and tight tolerances. This process utilizes advanced micromolding machines, precision molds, and high-performance materials to produce parts as small as a few milligrams.
compression molding

Compression Molding

Compression molding is a manufacturing process that takes a premeasured amount of thermoset rubber or silicone and presses it into the required shape while it vulcanizes into its’ final material properties. This process provides great elastomeric parts that can be used for o-rings or gaskets and have excellent mechanical and chemical resistance properties.
Liquid Silicone Rubber Molding service elimold 01

Liquid Silicone Rubber (LSR) Molding

LSR is an injection molding process that uses liquid silicone rubber to create flexible, durable, and heat-resistant components. LSR is injected into a mold in its liquid state, then cured at high temperatures to form precision-molded parts with excellent biocompatibility, chemical resistance, and thermal stability.
Multi Component Multi Shot Molding 3K Molding

Multi-Component (Multi-Shot) Molding (3K Molding)

3K molding (three-color molding) is an advanced multi-material injection molding process that allows three different materials or colors to be combined into one molded part in one production cycle. The process uses a dedicated multi-component injection molding machine to integrate materials with different characteristics to enhance the performance of the product.
Custom Thermoforming

Custom Thermoforming

Our extensive custom thermoforming capabilities mean we can provide products and services that exceed expectations and can meet your smaller production needs, especially if you do not want to invest too much money in tooling.

Injection Stretch Blow Molding ISBM

Injection Stretch Blow Molding (ISBM)

We use ISBM to manufacture high-quality containers, bottles, etc. for various industries. In the ISBM process, molten polymer flows into the injection cavity and after reaching the right temperature, the polymer is stretched and blown into the final shape. ISBM uses materials such as PET, RPET, PP, PC and Tritan for a wide range of applications.
Multi cavity molding

Multi-cavity Molding

Depending on the size of the part, we can mold multiple parts in a single mold. We use a special multi-cavity mold that allows you to produce multiple types of similar parts (such as the left and right sides or the top and bottom of a product) using a single mold. This service is especially useful if you need to produce a large number of small parts quickly.

Injection Molding Tolerances

All plastic materials expand and contract under the influence of heat and moisture. Our tolerance guides will provide more comprehensive information covering the behavior of common resin types under typical part features. We will work closely with you to optimize your design to make it more production-friendly. We will point out any areas where poor design may cause thermal stress, shrinkage, warping and other problems. Please refer to our design guides for more information on common defects and how to avoid them. Unless otherwise stated, we adhere to DIN 16742 standard tolerances for plastic injection molded parts. Learn about our cosmetic quality standards for injection molded parts.

In-house Mold Design And Production

To ensure maximum productivity and minimize wasted time, we are able to complete end-to-end production of molds in-house, from design, mold filling analysis, CAM, CNC machining, EDM, bench machining, assembly to trial molds. We call this Engineered Mold Manufacturing.

  • High-precision mold production equipment operates 24 hours a day, further reducing lead times
  • Molds are cut according to customer CAD data and specified materials (including manufacturer specified shrinkage). Mold tolerances are typically +/- 0.005″. If a customer requires a molded part with
  • tighter tolerances or specific tolerances, we will review the request on a case-by-case basis. Tighter tolerances will increase lead times and production costs.
  • Elimold offers a “Lifetime Injection Mold Guarantee” – this service means that we will store the customer’s molds indefinitely for future production if there is a follow-up order or a nominal storage fee.

Mold Cavity Tolerances

We are able to maintain mold cavity tolerances within +/- 0.05 mm (or +/- 0.002 inches), ensuring that every product we produce is accurate. These extremely tight tolerances are critical in industries where even the slightest deviation can affect the function of the product. We hold each component to such a stringent standard that it will fit precisely into your assembly without any adjustments, ensuring consistency during large-scale production. You can request tighter tolerances, but doing so may increase tooling costs due to the need for more sampling and trimming.

What is Injection Molding?

Injection molding is the process of injecting molten plastic into a mold cavity, rapidly cooling it, and then ejecting a solidified plastic part. It is the most widely used manufacturing process for plastic parts and the most economical way to mass produce them. Once a metal mold or tool is made, hundreds, thousands, or millions of plastic copies can be made in a short period of time, and each additional mold reduces the actual cost of each part as the mold cost is amortized. Injection molding is compatible with a wide range of materials: including thermoplastics, thermosets, and even metals, and these materials can be easily mixed with color pigments and other additives to adjust the function and appearance of the molded product. Therefore, the injection molding process provides excellent consistency from unit to unit because the tooling always remains unchanged.Injection molding also has the most variety in materials, colors, finishes, finishes, and surface textures compared to CNC machining or even 3D printing.

what is injection molding
molds inset service01

Advantages of Injection Molding

Injection molding is the preferred manufacturing process for industries that need to produce high-quality, complex and scalable parts. Its main advantages are as follows:

  • Capable of complex designs
  • Wide material compatibility
  • Strong and durable parts
  • Suitable for mass production with short production cycles
  • Lower cost per part as production scales up
  • Efficient use of materials and reduced scrap
  • Consistent quality and tight tolerances
  • Wide selection of colors and textures

Differences between injection molding and 3D printing

In the molding process, plastic or metal parts are formed inside a mold. They are then removed from the mold as fully formed parts. 3D printing is an additive manufacturing process, which means that the parts are built layer by layer using processes such as deposition or sintering. Injection molding is well suited for high-volume production with consistent quality, while 3D printing is better suited for prototyping and small batch production. Injection molding can produce more durable parts. The cumulative cost of 3D printing can be staggering. Once part production reaches a certain level, the unit price of injection molding will be much lower than 3D printing. With the injection molding process minimizing capital investment, the smart move from 3D printing to injection molding will come faster.
