Plastic injection molding for manufacturing custom parts
We manufacture custom parts using plastic injection molding for industrial projects that require control, continuity, and a supplier capable of handling multiple phases. At GB Inyectados, we combine in-house manufacturing, technical expertise, and process monitoring so you can bring your part to production with fewer intermediaries.
Types of parts we can produce
Our plastic injection molding processes allow us to manufacture technical parts, industrial components, and custom products with different geometries, dimensions, colors, and finish requirements. We work both from an already defined design and on projects that require a review of the part before moving to production.
We can manufacture components that are part of an assembly, parts with mechanical functions, housings, protective elements, flexible parts, consumer products, and items that require a refined appearance. We also take on projects in which the part must fit with other components or meet specific conditions for use and assembly.
Before production, we assess the part’s requirements, the intended material, the production volume, and the condition of the mold. This comprehensive approach helps us approach each job from a production perspective, rather than as an isolated part.
Geometry and material analysis
We review the geometry, functional areas, wall thicknesses, and factors that may affect manufacturing. We also analyze the material based on the part’s required performance, rigidity, flexibility, appearance, or operating conditions. If the design requires adjustments to ensure greater stability during production, we’ll let you know which aspects need to be reviewed before moving on to the mold.
Mold, testing, and Fine-Tuning
In thermoplastic injection molding projects, the mold must perform well when production begins. We manufacture or inspect the mold, conduct machine tests, and adjust the parameters until we achieve a consistent part. If your project requires a new mold, we also develop plastic injection molds designed to operate reliably and continuously in mass production.
Production and repeatability control
During the injection molding of parts, we monitor the process to ensure consistent results across cycles and batches. We inspect the part, its finish, and the parameters that affect its consistency. We use specialized machinery and technical supervision to ensure that an approved design can be consistently replicated whenever you need new production runs or need to increase the planned volume.
Thermoplastic materials and engineering plastics
The material determines how a part behaves, how it is processed, and what performance characteristics it can maintain during use. That’s why, before plastic injection molding, we assess the project’s requirements and select the material that best meets those conditions.
We specialize in PVC and thermoplastic rubber and also work with TPE, ABS, nylon, PP, PE, PS, and K Resin, as well as technical materials that we evaluate based on the part’s requirements. We have specific experience with flexible PVC, which is especially useful for products and components that require elasticity and adaptability.
The choice depends on factors such as stiffness, flexibility, finish, dimensional stability, contact with other elements, or operating conditions. If the material has already been specified, we work according to those specifications. If it is still undecided, we work with you to determine what requirements the part must meet before finalizing the manufacturing process.
Production series, capacities, and scalability
Manufacturing an initial batch is only part of the job. When a product must remain in production, you need to know that your supplier can repeat the production run and keep pace with growing demand. For our custom plastic parts, we have our own fleet of injection molding machines ranging from 35 to 320 metric tons, which allows us to adapt production to projects with different requirements.
We plan each order based on the expected volume, the material, the part’s production cycle, and the continuity you require. When working with recurring orders, we organize production to maintain a consistent product specification across different runs and control the factors that can influence the outcome.
Having our own machinery also gives us greater control over deadlines, maintenance, and the monitoring of each production run. We can assess a specific production need or a project expected to grow in volume, always based on the part, the mold, and the technical specifications that define each series.
Finishing and Post-Processing operations
Assembly
We assemble parts and components when a product requires multiple parts or elements before it can be shipped.
Screen printing
We apply text, logos, symbols, or graphic elements to surfaces compatible with this system.
Pad printing
We print on parts with complex geometries that require a system capable of adapting to less-than-flat surfaces.
Painted
We apply a surface finish when the project requires a specific color or finish after injection.
Chrome-plated
We incorporate this finish into projects that call for a surface with a metallic appearance or specific aesthetic qualities.
Metallic
We include this process when the product specification requires a surface coating of this type.
Sectors and applications
Our plastic injection molding processes are tailored to projects in a wide range of industries because we analyze what each part needs to do and under what conditions it will operate. We manufacture for the plumbing, toy, sports, agricultural, electrical, and household sectors, as well as industrial components and consumer products.
Every project presents different needs. A plumbing part may require a tight fit and stability; a sports component may call for durability and a specific geometry; and for a consumer product, the finish, color, or surface appearance may be more important. We analyze these requirements before production to coordinate the material, mold, and process.
We also work on projects at various stages of development. We can start with an existing design and mold or take on a project that requires technical support, prototyping, tooling, production, and finishing. This allows you to coordinate all phases with a single point of contact.
