BACH INDUSTRY AG supports companies in the reliable procurement of custom plastic injection molded parts based on drawings, CAD data, samples or technical specifications. We work with a verified partner network and support projects from prototype to predictable series delivery. This gives you competitive prices, short coordination paths and quality-oriented implementation in accordance with ISO 9001.

Plastic injection molding is the economical solution for recurring plastic parts with defined geometry, consistent quality and high scalability. BACH INDUSTRY AG supports B2B customers in the procurement of injection molded plastic parts for mechanical engineering, equipment manufacturing, electronics, medical technology, sensor technology, industrial products and technical assemblies.
You can submit your project request with a PDF drawing, STEP file, 3D CAD data, sample part, bill of materials or technical specification. For a fast review, information on quantity, material, surface finish, color, tolerances, application area and desired delivery date is helpful.
Our approach is particularly suitable when you are not looking for standard parts, but want to procure custom plastic parts with clear technical and commercial requirements.
| Requirement | Typical Solution |
|---|---|
| Plastic part to drawing or CAD | Plastic injection molding with technical feasibility review |
| New components and first functional samples | Prototypes, pre-series production or project-specific tooling concept |
| Recurring demand from 5000 pieces | Small batches, medium-sized series or scalable series procurement |
| Complex geometries and functional surfaces | Injection molded parts with optimized tool and material design |
| Multiple materials or inserts | 2K injection molding, insert molding or overmolding after review |
| Price and delivery pressure | Verified partner network for cost-effective procurement |
The specific design depends on part geometry, plastic material, tooling concept, surface finish, wall thickness and quantity. Through our partner network, we can systematically review different requirements for injection molding, toolmaking, post-processing and assembly.
| Technical Point | Project-Based Guideline |
|---|---|
| Batch sizes | From 5000 pieces, from prototypes and small series to large-scale production |
| Part weight | From very small precision parts up to approx. 5 kg, depending on tooling and partner capacity |
| Tolerances | Up to approx. ±0.05 mm with suitable geometry, material selection and tool design |
| Clamping force | Project-dependent, from small systems to large machine ranges for larger molded parts |
| Processes | 1K injection molding, 2K injection molding, multi-component injection molding, insert molding, overmolding |
| Toolmaking | Prototype tools, series tools, tool optimization or tool transfer after review |
| Post-processing | Assembly, ultrasonic welding, printing, painting, inspection and packaging according to requirements |
Depending on the application, we review standard plastics, engineering thermoplastics and high-performance plastics. Key factors include mechanical load, temperature range, chemical resistance, dimensional stability, surface finish, color, flame-retardant requirements and cost structure.
In addition to conventional 1K injection molded parts, more advanced injection molding concepts can also be reviewed. These include multi-component parts, overmolded inserts and hard-soft combinations where function, design and assembly effort are already integrated into the component.
An economical injection molded part does not start in production, but with the right tooling strategy. Together with our partners, we review whether a prototype tool, series tool, multi-cavity tool or tool transfer makes sense. We consider target quantity, part geometry, material, tolerances, surface requirements and planned service life.
For existing components, existing tools, sample parts or previous production data can also be reviewed. This makes it possible to prepare alternative procurement routes, cost optimizations or more stable supply chains.
Many plastic parts require additional process steps after injection molding. Through our network, we can coordinate post-processing, assembly, printing, surface finishing, functional testing and packaging depending on the project.
| Additional Service | Benefit for Your Project |
|---|---|
| Ultrasonic welding or hot plate welding | Strong bonding of plastic components |
| Printing, pad printing or laser marking | Identification, scales, logos or technical markings |
| Assembly of inserts | Finished functional parts instead of individual components |
| Functional testing | Controlled quality before delivery |
| Packaging according to specification | Series-ready delivery for production, storage or assembly |
BACH INDUSTRY AG does not operate its own injection molding production, but works with a verified partner network. For many companies, this is an advantage: we are not limited to a single machine park, a specific tooling concept or fixed capacity. Instead, we select the right manufacturing solution for your component, your quantity, your quality requirements and your target budget.
Through a continuous project flow and the bundling of requests, we can enable competitive conditions. At the same time, you benefit from one central point of contact who supports technical coordination, partner selection, the quotation phase and project execution in a structured manner.
Plastic injection molding is suitable for technical and visual components that need to be manufactured repeatably, dimensionally accurately and economically. The process is particularly relevant for companies looking for a stable solution for series demand, spare parts, new products or assemblies.
To ensure that your project can be reviewed quickly and properly, we work with a clear request process. The better the technical data, the faster feasibility, tooling concept, material selection and price range can be evaluated.
| Step | What Happens? |
|---|---|
| 1. Send your request | You send drawings, CAD data, samples, a bill of materials or technical specifications. |
| 2. Technical review | We review geometry, material, tolerances, quantity, tooling requirements and quality requirements. |
| 3. Partner selection | We select suitable manufacturing partners from our network for injection molding, toolmaking or post-processing. |
| 4. Feedback | You usually receive initial feedback within 1 to 2 business days. |
| 5. Quotation and implementation | After technical coordination, you receive a structured quote for prototypes, small batches or series production. |
Do you need injection molded parts to drawing, a new plastic part for series production or a cost-effective alternative to your current procurement? Send us your data. BACH INDUSTRY AG will review your project and coordinate the right solution through a qualified partner network.
