Plastic injection molding is a manufacturing process in which molten plastic material is injected into a mold cavity, allowed to cool and solidify, and then ejected from the mold to produce a finished part.

A wide variety of thermoplastic and thermosetting polymers can be used in plastic injection molding, including polyethylene, polypropylene, polyvinyl chloride (PVC), nylon, and acetal.

There are several advantages to using plastic injection molding as a manufacturing process:

  • High efficiency: Plastic injection molding is a highly efficient manufacturing process that can produce large volumes of parts quickly and consistently.
  • Precision: Plastic injection molding allows for precise control over the shape and size of the finished parts, as the mold is created to produce parts with precise dimensions.
  • Consistency: The injection molding process produces parts that are consistently the same size and shape, which is important for many applications.
  • Automation: Plastic injection molding machines can be automated to a high degree, which can reduce the need for manual labor and increase production efficiency.
  • Versatility: A wide variety of thermoplastic and thermosetting polymers can be used in plastic injection molding, making it a versatile manufacturing process that can be used to produce a wide range of parts.
  • Cost-effective: Plastic injection molding is a relatively low-cost manufacturing process compared to other methods, particularly for producing large volumes of parts.
  • Durability: Parts produced through plastic injection molding are often highly durable and can withstand high stresses and strains, making them suitable for a wide range of applications.
  • Versatility of design: Plastic injection molding allows for the production of parts with complex shapes and designs that may be difficult to produce using other manufacturing methods.

The size of the plastic injection molding machine is generally determined by the size of the mold and the size of the finished parts. Larger machines are capable of producing larger parts and can handle molds with more cavities, which can increase production efficiency.

Contract manufacturing is the process of outsourcing the production of a product to a third-party manufacturer. This allows companies to focus on their core competencies, such as product design and marketing, while outsourcing the production process to a manufacturer that has expertise in that area.

Some factors to consider when choosing a contract manufacturer include the quality of their products, their reputation in the industry, their manufacturing capabilities and capacity, their location, and their cost. It may also be important to consider their level of experience and expertise in the specific type of product being manufactured.

The process of contract manufacturing typically involves the following steps:

  1. Identifying the product or products that will be manufactured by the contract manufacturer
  2. Researching and selecting a contract manufacturer that has the appropriate capabilities and capacity to produce the product
  3. Negotiating a contract with the contract manufacturer, including the terms of the agreement and the price for the product
  4. Providing the contract manufacturer with the necessary specifications, drawings, and other information needed to produce the product
  5. Monitoring the production process to ensure that the product is being produced to the required quality standards
  6. Receiving and inspecting the finished products from the contract manufacturer

The customer is responsible for identifying the product or products that will be manufactured by the contract manufacturer, and for providing the necessary specifications, drawings, and other information needed to produce the product. The customer is also typically responsible for monitoring the production process and ensuring that the product is being produced to the required quality standards.

The contract manufacturer is responsible for producing the product according to the specifications and requirements provided by the customer. This typically includes sourcing the necessary materials, setting up and operating the production equipment, and performing any necessary testing and inspection of the finished product.

Pricing in contract manufacturing is typically based on the cost of producing the product, including the cost of materials, labor, and overhead. Other factors that may be considered in determining the price include the quantity of product being produced, the complexity of the product, and any additional services being provided.

LS Plastech is constantly working on expanding our certifications. Our Quality Management System (QMS) is certified under the ISO 9001:2015 guidelines. We are currently in the process of achieving our IATF 16949 certification. LS Plastech is also a member of Operation Clean Sweep through ANIPAC as part of our commitment to the environment. We are open to apply for any certification requirements our customers may have. Certifications

Working with a Mexican plastic injection company can offer a number of benefits, including lower production costs, proximity to the United States, and access to a skilled workforce.

As contract manufacturers, our customers bring their product designs to us, and we guide them through our processes to quote molds and finished products. We can make recommendations for changes to their design that can save time and money in production. We do not design products from scratch but can help guide our customers on how to get started with their initial concepts.

Please get in Contact with us. Send us a Request for Quotation (RFQ) ready with part numbers, estimated yearly order volumes, resin specifications and descriptions. It will streamline the process of evaluating your design if you can provide part drawings, CAD files, a detailed description of end use and the operating environment. After we make recommendations regarding your design, we will discuss project timelines and request any additional information needed. The more information you can provide us with the more accurate and expedited your quotation will be.

It depends on the complexity of the part design, the number of cavities and mechanisms. The lead time is typically around 10-14 weeks.

Each project is unique, so lead times vary. There are many factors to consider such as: Are we building a mold or transferring an existing mold? Is the resin provided by the customer or sourced by us? Do fixtures, gauges or special stations need to be developed? In the quoting process we can develop a specific timeline to fit the needs for your project and get the product to market as soon as possible.

LS Plastech has no set minimum run size for a plastic part, but a small run size will have a higher cost due to the setup of the mold for production and startup efficiency ramp up. The cost of the resin will also be impacted by the lower order volume of the plastic resin.

LS Plastech as part of its value proposition can integrate several processes such as assembly, decoration, packaging and logistics in order to deliver the most value possible to its customers. It relies on using in-house processes as well as business partnerships to accomplish this. You may consult our Services section for a more extensive list.

We can ship your products to anywhere in the world. Shipping is quoted separately. Our customers may also pick up their finished products ExWorks.
