Deep engineering

Constructing an insurmountable micron moat [Silicone Mould]
Specializing in silica gel compression and LSR mold that challenges the limit.
We are well aware that mediocre molds cannot achieve excellent products. Therefore, we focus on tackling difficulties:

Complex structure expert

In view of the design challenges such as deep bone position, fine back buckle, multi-slide linkage and ultra-thin silicone parts (wall thickness < 0.2mm), we have mature die structure scheme and processing experience.

LSR precision injection technology

Expertise, an independent LSR cold runner and dispensing system, can effectively solve the problem of bubbles and flow marks in LSR molding, especially suitable for microfluidic chips, baby bottle straws and other products that require high cleanliness and transparency.

Application of materials science

We have established cooperation with top suppliers of raw materials such as Wacker and Mai Tu, which can test the properties of materials in advance for you, and provide guidance on the application of special formulas such as high temperature resistance (> 250°C), chemical corrosion resistance and high tear resistance.

Accuracy is not a slogan, but the result of system and equipment guarantee.
Whole process detection
From ultrasonic flaw detection of die steel, to CMM detection after CNC machining (accuracy ±0.002mm), and then to SPC statistical process control in production, we have built a closed loop of quality control throughout.
Data traceability
Every set of molds and every batch of production has a complete test report and data record, which provides you with a solid quality certificate and easily responds to customer and third-party audits.
Engineering empowerment
Free DFM, killing risks in the blueprint.More than 20 years of expert team, in the drawing stage to escort you.
Suggestion on demoulding angle
Avoid product strain and deformation caused by poor demoulding.

The True Symphony of "Plastic-Silicone Integration"

Modern products are often the perfect combination of various materials. Our value lies in realizing the integration effect of “1+1 > 2”

wearable smart devices

Equipment body (PC/ABS plastic)+waterproof sealing ring (silicone)+skin-friendly strap (TPU/ silicone). We ensure that the dimensional fit and structural design of all components are unified at the source.

Automobile powertrain

Engine intake pipe (nylon plastic)+joint seal (fluororubber). We understand the difference of material deformation in high temperature and high pressure environment and compensate it in design.

Flexible manufacturing

Seamlessly match every stage of your business growth.

Agile prototype

In early project stages, speed and cost are critical. Our rapid prototyping services, including 3D printing, CNC machining, and vacuum casting, deliver functional samples within 3-7 days.

Market climbing

We operate a flexible manufacturing unit specializing in small batch production. Equipped with 80T-350T medium injection molding machines and servo manipulators, it enables quick mold changes and economical production runs from just 100 pieces.

What is the precision level of your silicone molds?

Our silicone molds maintain stable tolerances within 0.05mm for key dimensions. Leveraging full-process quality management and coordinate measuring machine (CMM) inspection (accuracy ±0.002mm), we achieve micron-level molding standards, suitable for complex structures and ultra-thin components (wall thickness <0.2mm).

Which application fields do you support for customized silicone/plastic integrated products?

We cover six core fields: biocompatibility (medical-grade silicone), food contact (compliant with FDA/LFGB certifications), special industrial use, electronic products, outdoor sports, and high-transparency applications. We also specialize in "plastic-silicone" integrated products for industries such as automotive, medical, and consumer electronics.

What prototype manufacturing methods do you offer, and what is the lead time?

We provide three prototype solutions: 3D printed prototypes (delivered in hours, ideal for appearance evaluation), CNC machined prototypes (made of engineering plastics, for verifying assembly functions), and vacuum composite molds (10-50 pieces for small batches, with properties close to final products). The overall prototype lead time is 3-7 days.
